UNITED STATES DEPARTMENT OF AGRICULTURE, DIVISION OF ECONOMIC ORNITHOLOGY AND MAMMALOGY, Washington, D. C., July 20, 1887. Sir: I have the honor to transmit herewith, for publication as Bul- letin No. 2 of the Division of Economic Ornithology and Mammalogy, a special report upon Bird Migration in the Mississippi Valley in 1884 and 1885, by Prof. W. W. Cooke. Respectfully, C. HART MERRIAM, Ornithologist. Hon. NoRMAN J. CoLMAn, Commissioner of Agriculture. PREFATORY LETTER. The present report, which has been prepared by Prof. W. W. Cooke, with the assistance of Mr. Otto Widmann and Prof. D. E. Lantz, is the first fruit of the co-operative labors of the Division of Economie Or- nithology of the Department of Agriculture and the Committee on Bird Migration of the American Ornithologists’ Union. It consists of two parts: (1) an introductory portion treating of the history and methods of the work, together with a general study of the subject of Bird Migration, including the influence of the weather upon the move- ments of birds, the progression of bird waves and causes affecting the same, the influence of topography and altitude upon migration, and the rates of flight in the various species; and (2) a systematic portion in which the five hundred and sixty species of birds known to occur in the Mississippi Valley are treated serially, the movements of each during the seasons of 1884 and 1885 being traced with as much exactness as the records furnished by the one hundred and seventy c-bservers in the district permit. The chapters entitled “‘The Relation of Migration to Barometric Press- ure and Temperature,” and “A Study of the Bird Waves which passed up the Mississippi Valley during the Spring of 1884,” are worthy of the most careful perusal; and the articles on the Kingbird and Purple Martin, in the systematic portion of the report, are particularly in- structive. Indeed, I feel no hesitancy in expressing the belief that the present report is the most valuable contribution ever made to the sub- ject of Bird Migration. For the opinions herein expressed, relating to the theoretical questions involved in the study of Bird Migration, Professor Cooke alone is re- sponsible. Some of these opinions are diametrically opposed to those held by the editor, but in a few instances only has the editor taken the liberty to add his views on the subject; in all such cases the interpo- lated remarks will be found in bracketed foot notes, over his initials. In fact, it has not been thought proper to make any changes in the First Part of the report, save the verbal alterations necessary in preparing it for the press. In the Second Part, or “Systematic Report,” the case is entirely different, for this portion of the report deals with fact instead of theory. Here the editor has deemed it his duty to make the subject- matter conform to the present state of knowledge on the subject. With 5 6 this end in view, changes have been made freely, and the portions re. lating to the geographical distribution of the various species and sub- species have been largely rewritten. In this task the editor has received invaluable assistance from Mr. Robert Ridgway, Curator of Birds in the U. S. National Museum. The nomenclature adopted is that of the new Check List of the American Ornithologists’ Union, with the additions and corrections contained in Ridgway’s Manual of North American Birds, which, for- tunately, became available just as this report was going to press. The number in brackets following each name is that which the species bears in Ridgway’s Nomenclature of North American Birds, as published in Bulletin 21 of the U. 8S. National Museum, 1881. The admirable map which accompanies this report has been prepared under the supervision of Mr. Henry Gannett, chief geographer of the TJ. 8. Geological Survey. My own connection with the report has consisted in bringing together under the head of each species the matter contributed separately for the two years; in arranging it in accordance with the nomenclature of the American Ornithologists’ Union; in revising* the systematic portion of the report (Part Second); in incorporating the original Appendixt into the body of the text, and in the editorial revision of the manu- script of the whole report—a labor which, for the past year and a half, has consumed all of the time not required in the performance of my routine official duties. ‘ C. Hart MERRIAM, Editor. WASHINGTON, D. C., July 20, 1887. * This revision has consisted in rewriting the habitats of most of the species and subspecies; in casting out some forms which had been included upon erroneous identification or insufficient evidence; in correcting statements of fact; in transfer- ring (in a few cases) the notes sent under a stated species or subspecies to a nearly re- lated species or subspecies known to inhabit the region under consideration to the exclusion of the form reported; in the addition of a number of species and subspecies now known to inhabit the region; in the insertion of additional matter under species already given; in the interpolation of authorities for second-hand statements; and in the omission of matter of questionable reliability. In all of these directions the editor feels that the report is susceptible of still further improvement, but want of time and reluctance to longer delay the publication of an already long-delayed and much-clamored-for document must be his excuse for its incompleteness and imper- fections. +The original appendix consisted ofa very briefly annotated list of about one hundred and forty birds supposed to inhabit the District, but concerning which no reports had been received from our observers. Some of these have been aliminated, as resting upon insufficient evidence ; the remainder, for the convenience of those who use this book, have been incorporated in their proper places in the general text, accompanied by a statement of their geographical distribution, and such other facts of interest as might be added without too greatly increasing tue bulk of the report. FIRST PART. BIRD MIGRATION IN THE MISSISSIPPI VALLEY. By W. W. Cooke. In the winter of 188182 the attempt was made to secure the assist- ‘ance of the ornithologists of Iowa in studying the migrations of birds ; but a change of residence on the part of the author from Iowa to Minn- -esota necessitated a modification of the original scheme, and it was de- cided to increase the size of the aréa to be investigated so as to include the whole Mississippi Valley. All the ornithologists of that district were invited to co-operate by contributing notes on the winter birds and re- porting dates of the spring arrivals. Answers were received from 26 persons who promised to aid in the work, but at the end of the season it was found that but 13 had actually forwarded observations. These © 13 were distributed as follows: Arkansas, 1; Missouri, 2; Kansas, 1; Iinois, 3; Nebraska, 1; Iowa, 2; Minnesota, 2; Wisconsin, 1. Thus it will be seen that a small part only of the Mississippi Valley was rep- resented. The notes contributed were published, without comment or change, in Forest and Stream for October, November, and Decem- ber, 1882. The same work was undertaken for the spring of 1883, and, by a lib- eral use of the press, @ much larger corps of observers was obtained. The names of 42 persons were received, but of these 26 only furnished reports. They were distributed as tollows: Texas, 1; Mississippi, 2 ; Tennessee, 1; Kansas, 2; Arkansas, 1; Missouri, 3; Illinois, 7; Iowa, 4; Wisconsin, 2; Minnesota, 3—thus leaving Louisiana, Indian Terri. tory, Nebraska, and Dakota with no representatives. The larger part of the hundreds of notes received from these observ- ers was never written up, and for that reason frequent reference will be made to them in the present report.* Some of the species were treated in the Ornithologist and Oolégist for 1883, and the full notes from two of the stations appeared in the American Field for. December, 1883, and January, 1884, and were afterwards issued as Bulletin No. 1 of the Ridgway Ornithological Club of Chicago. The founding of the American Ornithologists’ Union (in September, 1883) greatly enlarged the scope of the work, but did not materially [* Since the above was written most of these notes have been printed in the Orni- thologist and Odlogist.—C. H. M.] 9 10 alter its character. As is well known, this society was formed of the most prominent ornithologists of North America, and gathered to itself the best of the younger active field workers. When, therefore, it was announced that, at the first meeting of the new Union, “‘a committee was also appointed on the ‘migration of birds,’ to co-operate with Mr. W. W. Cooke in connection with his work on this subject in the Mississippi Valley, and consists of the following gentlemen, with power to add to their number: Merriam, Brown, Pur- die, Wheaton, Chamberlain, Grinnell, Henshaw, Cory, Merrill, Fisher, Bicknell, Mearns, and Mcllwraith,”* a new impulse was given to the work, and ornithologists all over the district hastened to send their offers of aid. Under the efficient management of the chairman of the committee, Dr. C. Hart Merriam, arrangements for the spring campaign were soon completed. The whole of the United States, British America, and Alaska were included in the scheme, and the field was divided into fourteen districts, each under the charge of its own superintendent. The su- perintendency of the work in the Mississippi Valley remained in the same hands as for the two previous years, and the district was made to include Mississippi, the portions of Kentucky and Tennessee west of the Tennessee river, Illinois, Wisconsin, the northern peninsula of Michigan, Louisiana, Arkansas, Missouri, Iowa, Minnesota, Texas, In- dian Territory, Kansas, Nebraska, Dakota, and Manitoba. The work begun in the Mississippi Valley December 1, 1883, under the auspices of the American Ornithologists’ Union, has been carried on uninterruptedly to the present date. Its progress has been chron- icled from time to time in The Auk, and in the Ornithologist and Odlo- gist, in which latter magazine, for May, 1384, appeared a list of the observers and a rough map of the district, showing the location of the stations. Since then the names of many new observers have been added until the number at the close of the season of 1884 was 160. Reports on spring migration in 1884 were received from 109 stations. These reports may be characterized as follows: Merely a few notes, 25; a scattered report on the whole or a part of the migration, 50; a full re- port on the whole migration, 34. These 109 stations were distributed over the Mississippi Valley as follows: Mississippi, 6; Tennessee, 1; Illinois, 22; Wisconsin, 14; Louisiana, 2; Arkansas,1; Missouri, 9; Towa, 18; Minnesota, 11; Texas,4; Indian Territory, 2; Kansas, 5; Nebraska, 3; Dakota, 8, and Manitoba, 3. Reports were received on the fall migration of 1884 from about half a dozen observers. Individually, these reports were of a high grade of excellence, but their number was too small to allow of any accurate tracing of the southward movements of the various species. They will be found incorporated in the body of this report. * Bull. Nutt. Ornith. Club, Vol. VIII, 1883, p. 225. 11 THEORETICAL CONSIDERATIONS. Before proceeding to treat in detail of the phenomena presented by the reccrds of the migration observers, it may be well to glance for a moment at the general causes of migration, and at some of its more striking and interesting features. Without entering into a discussion of the causes which long ago started birds on their periodical change of habitation, we shall not be far out of the way in considering their present migrations the result of inherited experience. To be more explicit, the first migrations were doubtless very limited in extent and probably were intelligent move- ments which through repetition became habitual, and the habit was transmitted from parent to offspring until it has become, as we see it now, the governing impulse of the bird’s life. It is undoubtedly true that love of the nesting ground, which is to them their home, is the foundation of the desire for migration;* and year after year they find their way thousands of miles back to the same box or tree by the exer- cise of memory—not always the memory of the individual, but the memory inherited from numberless preceding generations which have passed and repassed over the same route. In the study of the yearly cycle of migrations there are two movements for which we must seek the cause—the restless pushing northward in the spring, in spite of cold, rain, sleet, and snow; and the southward journey in the fall. We have already stated that the northward move- ment is caused by a strong home love—an overpowering desire to be once more among the familiar scenes of the previous summer. The re- turn movement is obviously the result of two causes—the approach of winter and the failure of the food supply. Of these two, the latter is probably by far the more powerful, since it is well known that single individuals of species which retire far to the south often remain behind, and, favored by an abundance of food, withstand the most severe weather. Thus, many Red-headed Woodpeckers remain through the winter in the cold climate of northeastern New York, frequenting the heavy timber where there is a great quantity of their favorite food ;+ and it is not unusual for a few Robins to spend the winter in north- central Wisconsin, sheltered in the thick pine forests; while Ducks and even Wilson’s Snipe have been known to remain throughout the whole {*I cannot concur with Professor Cooke in the belief that ‘love of the nesting ground * * * is the foundation of the desire formigration.” Ina lecture on Bird Migration which it was my privilege to deliver in the U. 8. National Museum, April 3, 1886, I said: ‘* Some ornithologists of note have laid special stress upon the ‘ strong home affection’ which prompts birds to leave the South and return to their breeding grounds. To me this explanation is forced and unnecessary. Birds desert their winter homes because the food supply fails; because the climatic conditions be- come unsuited to their needs; because the approach of the breeding season gives rise to physiological restlessness; and because they inherit an irresistible impulse to move at this particular time of the year.”—C. H. M.] t Merriam, Bull. Nutt. Ornith. Club, Vol. III, No.3, July, 1878, pp. 123-124, 12 winter in Wyoming, near the hot springs, whose warmth keeps the neigh- boring waters and ground from freezing. Nevertheless, it is as yet un- explained why some birds, notably many of the warblers, retire in winter to such a great distance south, some even crossing the equator and pass- ing several hundred miles beyond. Certainly neither cold nor hunger can be the cause of such wanderings. It has been often noticed that during the fall migration many birds seem to be able to foretell the approach of storms from the north, and hurriedly depart southward, before human eyes can detect any signs of the coming change. There is a large accumulation of evidence on this point, all seemingly in support of the proposition which has been for- mulated by one of our leading ornithologists in the following words: “Birds discern approaching meteorological changes.”* Some ornithol- ogists deny this, saying that in such cases the birds have out-traveled the storm, in which they were at first caught, their superior powers of flight enabling them to pass ahead of it; or that they have been warned by the hasty approach of more northern birds coming from the area over which the storm was moving. , If we study fall migration merely, there seems to be no doubt of the trath of this statement, but if we include spring migration the question becomes much more involved. If birds discern approaching meteor- ological changes, why is it that so many thousands perish each year by being caught in storms and frozen to death? Certainly an approach- ing storm in spring must give just as plain and early a warning as one in the fall, yet the same birds which are said to foresee it at the latter time and escape, rush blindly forward a few months later and are over- taken, their death paying the penalty of their rashness. The hardy waterfowl (Ducks and Geese) push northward in the spring, encounter storms, and are turned back, only to repeat the same thing a dozen times before they reach their summer quarters, but each time, instead of avoiding the approaching storm, they do not retreat until its actual presence drives them back. If they can foresee these changes, then their love of home and their desire to return to it must be wonderfully strong. . SPEED AT WHICH BIRDS MIGRATE. In studying the speed at which birds proceed northward in their mi- grations one.is beset by many difficulties. To determine the compara- tive speed of the several species is easy enough, but to determine the absolute rate—the exact number of miles which a particular bird makes during one day’s journey—is beyond our power. If migration were a steady movement northward, with the same individuals always in the van, numerous careful observations might make it possible to arrive at an approximation to the truth; but instead of this, migration is per- formed something after the manner of a game of leap-frog.. While in *J. A. Allen, in Scribner’s Monthly Magazine for October, 1881, p. 938, 13 the fall migration the younger birds lead,* in the spring they loiter be- hind, and it is the old birds, those in whom we may suppose the love of home and the desire for procreation are strongest, which press for- ward so eagerly. Moreover, of these old birds, those which arrive first at a given place, as a rule, are birds which lived there the previous summer and which will remain there to breed.{ Thus the vanguard is constantly arresting itself, and the forward movement must await the arrival of the next corps, which may be near at hand or far in the rear. The movement of migration, then, is made up of a series of constant overlappings, and the real speed is evidently much greater than the apparent. Of this real speed of transit we can take no account, and our calculated rates, therefore, are of value only in so far as they show the relative speed of migration of the different species. In the accompany- ing report the speed of migration is calculated in the following manner: The most southern reliable record is selected for comparison with the most northern record of the same character; the distance in miles be- tween these two stations is divided by the number of days elapsing from the time the species made its appearance at the southern station to the date at which it was seen by the northern observer. The result gives the average daily rate of migration in miles for the species. For exam- ple: The Baltimore Oriole was seen at Rodney, Miss, (lat. 31° 52’), April 7. It was not seen at Oak Point, Manitoba (lat. 50° 30’), until May 25. It was therefore 48 days in passing over the 1,298 miles between the two stations, which gives an average speed of 27 milesa day. This subject will be treated as thoroughly as possible, since it has received little or no attention heretofore; indeed, there were no datain existence for its study until the notes were collected on which the present report is based. The first records published in this country relating directly to the speed at which birds travel appeared in the Ornithologist and Odlogist for January, 1884 (pp. land 2). These notes were based on the records of six species in the spring of 1883; and though the notes for 1884 are many fold more numerous they do not give grounds for a change in the general rate of speed set forth in that article. It must be kept constantly in mind, however, that no complete and scientific study of the subject is as yet possible, and that the present records are given merely because they are the best now obtainable, and because they may furnish some material for the use of the future student. The records of fifty-eight species for the spring of 1883 give an average speed of 23 miles a day for an average distance of 420 miles, [* The opinion here expressed by Professor Cooke, namely, that in fall young birds migrate before their parents, has been long accepted in Europe, but is contrary to the experience of most leading American ornithologists and to the evidence collected by the Committee on Migration of the American Ornithoiggists’ Union, as will appear in a future publication of the Division. See, also, Mr. Brewster’s recent essay on the subject, in the Memoirs of the Nuttall Ornithological Club.—C. H. M.] {tThis statement needs much qualification.—C. H. M.] 14 A slightly smaller number of species for the spring of 1884 give exactly the same average speed over an average distance of 861 miles. Hence it is probable that future observations will not materially change this estimate. A study of the records for 1883 led to the statement that in spring birds migrate more rapidly in the northern portion of their routes of travel than in the southern. As this statement was based on the notes of one year only, it became a matter of much interest to ascertain whether the facts observed would hold good in future seasons and thus admit of formulation as a general law, or whether they had been the results of specially favorable conditions in the latter part of a single season. Accordingly, in the spring of 1884, twenty-five species of well- known birds, concerning which we had full records, were selected for careful study. The result bears out the foregoing statement. The dis- tance traveled was divided as nearly as possible into two equal por- tions and the speed was calculated for each. Some of the records do not admit of division ; others show an, equal speed throughout; while six show an increase of 77 per cent. in speed for the northern half, and three show a decrease of 47 per cent. Thus it will be seen that the record is strongly in favor of the increase. The same result may be reached by calculating the average speed of these twenty-five species separately for each of the different months in which migration is per- formed; the average speed for March is 19 miles, for April 23 miles, and for May 26 miles, per day. The record for 1884 also confirms the statement that the later a bird migrates the higher average speed it will attain. This would naturally be inferred from the preceding re- marks. These calculations are averages which give the rate of speed at which the bird would travel provided it moved regularly each day. But we know that many pauses occur, that on many days there is no advance ; heuce, on the days of movement the speed must be much higher than that given. Thisis clearly seen in the case of. the Purple Martin. From latitude 38° 40’ to 46° its average rate is but 13 miles a day; but we have good reason to believe that there was a pause from April 3 to April 14, and another from April 18 to May 3. Taking out the first of these pauses, the rate is raised between latitude 38° 40’ and latitude 43° 43/ to 35 miles a day, and, not counting the second pause, the rate for the rest of the distance is 28 miles. We must also take into consideration the fact that in all probability the same bird seldom migrates for several nights in succession, but stops to rest after a flight of a night or two, so that the birds migrating one night are not the same individuals that were moving the night be- fore. It has been stated above that the average rate for April is greater than that for March, and is exceeded by that for May; but it cannot be said that the actual number of miles performed in a night’s journey 15 is therefore greater. This may or may not be the case. The facts observed will be sufficiently clear if it is remembered that the later in the season a species moves the Jess hindrance it will meet from the ele- ments, and the fewer pauses will be necessitated in its journey. Dur- ing the month of May there are few if any nights in which migration does not take place; while a bird that migrates in March must expect to be stopped by storms at least one week in four. In regard to the relative speed at which the different species travel, all that can be said at present is that those which migrate later have, as a rule, the highest rate. Thus the average speed of the Robin, Cow- bird, and Golden-shafted Flicker is about 12 miles a day, while the aver- age of the Summer Redbird, Baltimore Oriole, Ruby-throated Hummer, — and Nighthawk is 28 miles. If we try to calculate the relative speed of the different families, we find that some of the species in a family mi- grate early and slowly, others late and rapidly, bringing the average of most of the families very close to the general average of all, which, as already stated, is 23 miles a day. es Birds have seldom been seen while on their way in undisturbed mi- gration at night. The observations given by W. E. D. Scott and J. A. Allen (Bull. Nutt. Ornith. Club, Vol. VI, 1881, pp. 97-100, and 188) are the most important, but in these nothing is said concerning the speed at which the birds were supposed tobe moving. It is known that birds do not move rapidly, as a rule, when migrating in the day-time, but from the meager material at hand it may be inferred that the speed at night is considerably greater. During day-migration the smaller land birds rarely fly faster than 15 miles an hour, though the larger birds, such as Cranes, Geese, Ducks, etc., move much more rapidly. At Red Rock, Ind. Ter., between August 25 and September 5, 1884, the Cliff Swallows and Nighthawks were conspicuous every morning and even- ing, slowly drifting south and southwest in their fall migration. For an hour and a half parties of birds would pass by in almost unbroken succession. Many hundred Nighthawks were seen during a single even- ing, and the number of Swallows was much greater. The result of timing them on several occasions gave a rate of about 10 to 14 miles an hour, the former being the more usual speed. This slow rate was caused by the irregularity of the flight, as the birds captured their evening and morning meals on the wing. The morning flight lasted an hour only, and was made at about the same speed. Thus a distance of about 30 miles would be traveled by each individual during the morn- ing and evening together, but no one can say how much farther, if any, they traveled during the night.* The advance of the hosts of Warblers, as they move incessantly for- ward from tree-top to tree-top, is still slower, probably being but a few miles during a whole day. Geese in their northward flight along the {* The material gathered from the keepers of light-houses seems to indicate that neither Swallows nor Nighthawks migrate to any extent after night fall—C. H. M.] 16 Atlantic coast traverse great distances, sometimes covering from 300 to 600 miles at a single flight; and it cannot be said positively that the larger birds do not do the same over the land. Still, the records so far made seem to indicate that the smaller land birds, such as Warblers; Finches, and the like, do not perform long journeys at one time when over land, but their voyages over the Gulf of Mexico prove that even these small species possess great power of flight. The preceding discussion shows that we are entirely wanting in exact knowledge on the subject, and that for some time to come all we can hope to do is to gather material. In this connection the facts accumu- lated by the keepers of light-houses are of the utmost importance, and the publication of the report containing these data is looked for with great interest. THE RELATION OF MIGRATION TO BAROMETRIC PRESSURE AND TEM- PERATURE. In studying the spring migration of 1884 use was made of the tri-daily weather reports of the Signal Service, of which about 50 stations were in or near the Mississippi Valley. These reports give the temperature, state of barometer, dew point, direction and force of wind, amount of rainfall, and character of the sky. The observations on which they are based were taken at7a.m.,3 p.m.,and11p.m. In the following study the 11 p. m. records were used for those birds which migrate by night, and the 7 a. m. records for such species as Ducks and Geese, which per- form the bulk of their movements in the forenoon. To render the study more easy, weather maps were made, one for each day, based on the 11 p. m. observations. The maps were made as nearly as possible like those now printed daily by the Signal Service at Wash- ington; that is, the state of the weather and the direction of the wind were marked at each station on the map in symbols which are plain and easily. comprehended, so that the eye could take in at a glance the gen- eral state of the weather in the whole Mississippi Valley. At each station the temperature, state of barometer, and force of wind were indi- cated. Dotted lines were then drawn connecting all places having the saine temperature, and solid lines connecting places of equal baromet- ric pressure. The former, called isothermal lines, were drawn for every five degrees of Fahrenheit; while the latter, called isobaric lines, were drawn for every tenth of an inch of pressure. The area of the lowest pressure is never stationary, but is constantly moving, and in an east- erly direction. It may be moving northeast, east, or southeast, and rarely north or south; but never northwest, west, nor southwest. The’ usual direction in the Mississippi Valley is a little south of east. It so happens that the particular wave which we study moves northeast- ward, but this is an exception to the general rule. Though it may move south or north. for a time, it will surely turn east in the end. In the body of the report, under the Purple Martin, the relation of a 17 migration to atmospheric cold and warm waves is discussed, and the statement is there made that the warm waves begin in the northwest and move toward the southeast. The cause of this lies in the move- ment of the area of low pressure. It is a law of the movement of winds that they go toward an area of low pressure, and from an area of high pressure. If, then, an area of low pressure develops, say in southwestern Dakota, it will be but a few hours before a south or southeast wind will be blowing over Nebraska and Kansas, and a warm wave will be started in these States. As this area passes eastward to Minnesota its effect will begin to be felt in Iowa, Missouri, and Arkansas, while by the time ‘it has reached Lake Michigan it will probably have produced southeast winds even to the Gulf of Mexico. But an area of low pressure is fol- lowed by one of high pressure, producing an opposite effect, and the isotherms which bent north to welcome the coming of the low area turn rapidly southward before the icy breath which blows from an area of high pressure. Thus the cold and warm waves both come frem the same quarter, and both move in the same direction; that is, the direc- tion in which the area of low pressure is advancing. Since it is known -that low pressure is generally accompanied by clouds and rain, while areas of high pressure are cloudless, it would be naturally supposed that migration would take place during high pressure; but, as has already been stated, the area of low pressure attracts a south wind, and the increased warmth more than overbalances the cloudiness. Fully 60 per cent. of the spring migration of 1884 took place in cloudy weather. It is probable, though I am not aware that it has as yet been proved, | that in the fall migration the reverse is the case, and the larger move- ment takes place in clear weather. Following is a fall record of the relation of migration to atmospheric conditions for the seven days from March 19 to 25, 1884, contrasted with a week’s migration in May. March 18, 1884, at 11 p. m., there was no marked atmospheric dis- turbance throughout the United States. The minimum of the cold wave had occurred the day before and the temperature was gradually rising in the Upper Mississippi Valley. Itis this part of the Mississippi Valley (from latitude 39° northward) to which the present study is con. fined. The temperature was quite high (50° at Saint Louis, and 37° at Saint Paul), but fell rapidly from Saint Paul northward tili it reached 20° at Moorhead, Minn.* The barometer varied only two-tenths of an inch from 29.9 inches in eastern Arkansas and southern Illinois to 30.1 at Moorhead, Minn. The prevailing winds were very light E. to N. The weather was cloudy, with several light rains. There was little change toward the morning of March 19, except the shifting of the wind to N. and NW., while the area of low pressure moved east to Cape Hatteras. Very little migration took place, and the few birds that *Tt need hardly be said that no one can follow these remarks intelligently without referring to the map accompanying this report. 7365—Bull. 2 2 18 were moving northward may be well called “birds of the first wave,” that is, Ducks, Geese, Blackbirds, Meadowlarks, Robins, and Blue- birds. These are the birds with which we have to deal in the study of these seven days. Migration was reported from southern Wisconsin and northern Illinois, against a northeast wind, with the temperature but two or three degrees above freezing, and from east-central Kansas under slightly warmer conditions. It seems likely that some of these notes belong to a warm wave which occurred two days before, but it is also certain that some Ducks and Geese were migrating in the early morning hours, straight against the northerly winds. , March 19 at 11 p. m.an area of slightly lower pressure had just passed over the Upper Mississippi Valley, and the barometer rose steadily all night. Between Saint Paul and Saint Louis the temperature re- mained the same as the day before; northward it was slightly higher; the winds were light, and were everywhere from NE., NW., and W. The temperature ranged from 45° at Saint Louis to 24° at Moorhead. The average barometer, at 11 p. m., was 30.07 inches, and at 7 a.m. of the 20th, 30.15 inches. Cloudy weather was reported everywhere ex- cept in the Lake Superior region. In general, the condition may be said to have been very unfavorable for migration, yet new arrivals were still noted from the same places as on the day previous, with the ad- dition of records from southeastern Dakota, eastern Iowa, and south- central Iowa. It would seem that the Ducks and Geese were so desirous of reaching their breeding grounds that they pushed northward in spite of the wind and the clouds, as soon as the temperature rose two or three degrees above freezing, regardless of the fact that the winter’s snow still covered the ground, and the lakes and rivers were still bound ‘with ice. Not until a week later did any streams open in the region . which was now being invaded by the migrating hosts. March 20 was characterized by very high barometer and by a marked advance of the isotherm of 30° to points north of Duluth an Moor. head. There was no place in the Upper Mississippi Valley at 11 p. m., March 20, where the pressure was less than 30.2, and in western Da- kota it was 30.3. Calm weather or very light north winds prevailed, with clear weather along the Mississippi and the Great Lakes, and cloudy weather with light rains on the Missouri. The minimum tempera- ture at Saint Louis was 43°; at La Crosse 37°; at Saint Paul 20°, and at Moorhead 23°. It was a moderately fair night for migration. The culmination of the high pressure was reached, and already in the south- ern Rocky Mountain region the low pressure was developing which was to bring about the immense movements which took place during the next three days; already the isotherms in that quarter were begin- ning to move northward and the wind along the Gulf coast had changed to SE. The birds seemed to have a foreknowledge of the approaching change, for twice as many ‘firsts’ were recorded as during the two previous days. Some of these came from central Missouri, where the: 19 change was at this time slightly felt. The main portion came from the same districts as on the day previous. There was practically no ad- vance of the van, but a filling up of the country already traversed by the scouts. On the night of March 21, at 11 p. m., an area of low barometer (29.9 inches) was passing eastward across the Upper Mississippi Valley and was central at North Platte, Nebr. It produced SE. winds of moderate strength in all the Mississippi Valley except the extreme northern part, above La Crosse. The temperature rose throughout the district to 56° at Saint Louis and 35° at Saint Paul; but north of this, beyond the in- fluence of the SE. wind, it fell rapidly to 18° at Moorhead and 11° at Saint Vincent. The isotherm of 40° was carried up to La Crosse. As morning approached, the temperature still rose in the northern part and the sky became overcast with some local clouds and rain. It was a night of much migration, owing to the influence of the area of low pressure, which at 7 a. m., March 22, was central at Omaha and Yank- ton, where the barometer at 3 p. m. registered 29.74 inches. This was a fall at Yankton of .32 inch during sixteen hours, while the center of the low area moved but a few miles; and the necessary result was a great rise in temperature and consequently great movements among birds. But the movements took place only to the east of the low press- ure area; for it is a law of atmospheric circulation that the winds are attracted from the south, not directly toward the center of the low press- ure area, but toward places to the east of it in the same direction that it is moving, while the winds which it attracts from the north move toward places to the west or behind it. Migration, therefore, would be looked for in vain to the south, west,or north of Yankton. The whole of this immense movement, which in number of records was as great as that of the three previous days together, and in number of individuals was many times greater, took place to the southeast and east of Yank- ton. The SE. winds prevailed up to La Crosse, and this place also marked the limit of the night's movement in that direction. A map was made of the migration which took place on this day, and it was found to cover a very nearly circular area, 250 miles in diameter,.the center of which was midway between Keokuk and Davenport. Some idea of the great number of birds which were migrating during this ni ght may be had from the fact that at Saint Louis twenty-six different species were noted as having arrived or increased. It is well to bear in mind that all these birds were migrating on a rapidly falling barometer, hence in the face of what is usually considered a sign of an approaching storm ; and it may be noted also that all this great movement did not advance the van, which remained where it had been before. March 23, bird migration was at a standstill. The area of low press- ure, which was central at Yankton in the afternoon of the 22d, had moved to Saint Paul by 11 p.m., the barometer falling steadily to 29.61 inches. During the night it moved NE. to Marquette, Mich., falling 20 still more to 29.56 inches. In the mean time an area of high pressure developed at Dodge City, Kans. The effect on the wind was as fol- lows: From Saint Louis southward the winds began to shift to SW.; to the northwest of that place they became NW. and N.; while to the northeast of Saint Louis they shifted to SW. and W. As would be expected, those places which had W. and NW. winds had clear skies, while the district from Saint Paul and La Crosse to Chicago and east- ward was cloudy. The temperature from Saint Paul northwest, north, and northeast rose. At Saint Paulit was stationary, and thence south- ward it fell a few degrees, but stillremained warm. The, wave of migra- tion seems to have exhausted itself in a single night. Some forty ‘firsts’ were recorded for this day, but, except at two places, they seem to have been arrivals of the previous day, which had been over- looked. These two stations, Waupaca, Wis., and Heron Lake, Minn. (with its neighborhood), furnished one-half of the forty records, and both’are on the northern edge of the district covered by the preceding night’s migration. It seems, then, that at these places there was a local, though, in the case of Heron Lake, a very large migration. March 24 was marked by cloudy weather after a clear night. South- erly winds prevailed over the Upper Mississippi Valley, varying from SE. to SW., and mostly light. The temperature had fallen, on an av- erage, 5° from Chicago to Bismarck and northward. It had risen strongly 9° to 11° at Yankton and Omaha, this rise probably being the cause of the arrival of immense numbers of water-fowl during the day at Heron Lake, Minn., all coming from the west, that is, from the direction of Yankton, at which place at 7 a. m. aS. wind was blowing. It was a day of general low pressure. The whole district, from Cairo to Moorhead, was included between 29.80 and 29.89 inches. Northward and eastward, in Manitoba and at Marquette, Mich., the barometer fell to 29.65; in the southwest, at Fort Smith, Ark., it fell to 29.71; and westward, at Deadwood, Dak., it rose to 30. An area of low pressure developed at Fort Smith, Ark., in the early evening of March 23, and became pronounced during the next twenty-four hours. At 7 a. m. of the 24th the effect of this area was hardly felt, but by night the wind had been attracted to it over most of the Upper Mississippi Valley, bringing from the north colder, clearer weather. This day, therefore, was the turning point, and the beginning of a cold wave which was already felt to the northwestward of Cheyenne. The temperature at 11 p. m., March 24, was 47° at Saint Louis, 42° at Chicago, 50° at Des Moines, 37° at Saint Paul, and 32° at Moorhead. This was the last day of the warm wave which commenced on the evening of March 21, and the birds made the most of their opportunity aud advanced a whole degree farther north. The hosts which had rested during the night of the 22d moved forward and fully ocenpied all the country up to latitude 45°, with an innumerable host along the Mississippi River at 45° 25’, and scouts up even to 47° on the Mis- souri. 21 That this was the culmipation ig easily seen from the records, which fell from seventy-three notes on the 24th to but seventeen the next day. Let us now calculate the average conditions under which birds were migrating during these seven days. A few more than three hundred records of ‘firsts’ were contributed for these seven days, and the tem- perature at which the species were migrating is found to be as follows: 250, one record (a Goose, in more senses than one) ; 29°, a cousin to the last; 31°, eighteen firsts; 33°, twelve firsts; 35°, eleven firsts; 37°, forty firsts; 39°, forty-one firsts; 41°, fifty-two firsts; 43°, sixteen firsts ; 45°, twenty-five firsts; 479, five firsts; 49°, seventeen firsts; 51°, nine firsts. Thus it will be seen that the favorite temperature for mi- gration of “birds of the first wave” ranges from 37° to 419 Fahrenheit. In cloudy weather there were 143 records; in clear weather 101, or exactly 60 per cent. cloudy, to 40 per cent. clear. With reference to the wind, it has been found that with the wind north there were 29 records; NE., 31; E.,12; SE., 75; 8., 23; SW., 27; W., 39; and NW., 9. It will be noticed that the most unfavorable winds, namely, the E. and NW., are directly opposite those winds which have the greatest number of records. Combining, we have for E. and W., 51 records; for NW., N., and NE., 69; and for SE., 8., and and SW., 125 records, showing how greatly the birds prefer a southerly wind to help them on their journey. The effect of barometric pressure will appear from the following statement: March 19 there were 24 records with an average pressure of 30 inches; March 20, 35 records at 30.04inches; March 21, 43 records at 30.24 inches ; the 22d, 82 records at 30.15 inches ; the 23d, 45 records at 29.80 inches ; the 24th, 73 records at 29.85; and the 25th, 17 records at 29.86 inches. These give an average of exactly 30 inches, or the normal pressure; but it must be remembered that the great wave of the 22d began when the pressure was very high and took place on a falling barometer. It is probable that a large number of observations taken throughout the season would give from 29.93 to 29.95 as the average pressure at which most birds migrate. The above study of the influence of atmospheric conditions upon mi- gration pertains to a single week in March, when the first wave was passing over the Upper Mississippi Valley. A similar study will now be made for a week in May, just before the close of migration for the spring. The seven days from May 4 to May 10, 1884, have been chosen. This brief period includes two warm waves and an interim of inde- terminate nature. Naturally, the birds were migrating under very dif- ferent conditions, and, as a result, a very different set of birds was con- cerned. One may look in vain for notes on Ducks, Geese, Robins, and other early species. In their stead the brilliantly-colored Orioles, Gros- beaks, Indigos, and Tanagers will be found. In the place of the frost and cold of March, there is a summer temperature with frostless nights, and swarms of insects are ready for the Warblers, Vireos, and Fly- 22 catchers. But the laws of atmospheric movements remain unchanged, and their effect on the movements of birds is the same in kind, but slightly different in degree. «|aaced F 38 35 WIAD RIAN occ csiciesis cicsnainutacracaitwia wiecie tedneulednace Odi 5 se 38 39 Hon.

B, Diente: Jn the fall of 1884 the last Mockingbird left Mount Carmel, Mo., Oc- tober 21, while the bulk left October 10. At Shawneetown, Ill, a single bird was reported as staying all winter, and at Peoria, lll, the species has been seen in midwinter. At Gainesville, Tex., some Mockingbirds spent the winter of 1884-85. In the spring of 1885, at Gainesville, Tex., the number present during winter was increased March 6 by the arrival of the first migrants, and 266 the species had become common by March 31. Mockingbirds reached Pierce City, Mo., April17; Peoria, Ili., April19; Griggsville, I., April 21; Saint Louis, Mo., April 24; Mount Carmel, Mo., May 2, and Man- hattan, Kans., April 26. In the fall of 1885 the last was seen at Saint Louis, Mo., October 24. Mr. Lloyd states that it is an abundant resident in Tom Green and Concho Counties, Tex. 704. Galeoscoptes carolinensis (Linn.). [12.] Catbird. A common summer resident throughout the Mississippi Valley and Manitoba; rare in southeastern Texas (Nehrling). In the spring of 1884 fifty-one observers contributed notes upon the movements of the Cat- bird. It was reported as a winter resident at Waverly, Miss., and at San Angelo, Tex. At the latter place it was marked “occasional.” Its northward movement in migration does not take place until the weather becomes warm and settled. Curiously enough, its first ap- appearance in 1884 was reported from Danville, Ill. (lat. 40° 08), April 3; while at Rodney, Miss. (lat. 319 52’), it was not reported until April 13. April 18 it was noted at latitude 41° 10’ in Illinois; and April 20 at latitude 40° 50’ in Iowa. Five days later one was ob- served at Saint Louis (lat. 38° 40’). Looking at these few records and knowing little of the state. of the weather during these three weeks of April, one would imagine that the Catbird was exceedingly erratic in its movements; and a further study of the records might do little towards dispelling this opinion. Taking the eastern line of migration, from Mississippi to Wisconsin, we find a general advance about April 29. On that day and the next it was reported at various stations in Illinois, from Hillsborough (lat. 39° 12’) to Chicago (lat.41° 51’). By May 7 the van had reached West Depere, Wis., and the bulk had arrived at Hillsborough and Polo, Il. It was reported as arriving at Green Bay, Wis., May 8, and the bulk reached the same place May 15. West of the Mississippi the earliest arrival was reported from Burlington, Iowa, April 20. April 26 the bulk arrived at Pierce City, Mo. April 28 Catbirds had appeared at Fayette, Mo., and Manhattan, Kans., while at Saint Louis they were still scarce. April 29 the bulk appeared at Saint Louis, at which place both sexes were at breeding stands, and flocks of transients were pres- ent. April 30 the first was reported from Des Moines and Coralville, Towa, while the bulk arrived at Manhattan, Kans. On the same day they first appeared at Oak Point, Manitoba. This last must be either a mistake or an extraordinarily early record. A delay of nearly a week in the general movement followed. May 8 the first was noted at Ames and La Porte, Iowa, and at Vermillion, Dak.; May 9 at Minneap- olis, Minn.; May 11 at Elk River, Minn.; and May 17 at Frazee City, Minn. In all cases the bulk followed within a week after the first in- dividuals had been seen. Jfarther west, on the plains, where fewer in- dividual of these species are met with, they were reported as arriving 267 somewhat later, At Gainesville, Tex., they appeared May 12, and re- mained about two weeks. At Alda, Nebr., the first arrival was May 14, while at Ellis, Kans., farther west, and in latitude 38° 55’, they were not seen until May 25. The notes received from observers contained little more than the dates of first appearance and the arrival of the bulk. The few records from near the southern border of the district leave us in doubt as to the extent to which Catbirds wintered in that section; but we know from previous records that they are somewhat common in the Gulf States east of Texas, and occasionally in mild win- ters a few have been found in southern Illinois; but in Texas, even , in the southern part, the Catbird is rare during the winter, and not very common during migration or in summer. The notes from Mr. Wid- mann, of Saint Louis, are in striking contrast to those of most observ- ers. They read: ‘ April 25, first one mewing; April 28, still scarce; April 29, bulk arrived; May 5, height of season, great numbers present, chasing, singing, mewing, fighting, bulk of transients present; May 8, bulk of transients departed ; May 10, building. The Catbird is also reported as building at Manhattan, Kans., May 9. In the fall of 1884 only four notes were contributed on the migration of the Catbird. At Williamstown, Iowa, the bulk departed August 28, and the last was seen September 11. At Unadilla, Nebr., the last was seen August 9; at Des Moiues, Iowa, September 24; and at Mount Car- mel, Mo., September 22; the bulk having left one ‘week previously. In the spring of 1885, the earliest record of the movements of this species came from the northern edge of its usual winter home. At Corinth, Miss., the first was seen April 9, but no more until April 14. By April 17 they were reported at Shawneetown, IIl., probably coming with the warm wave which culminated there the night before. At Saint Louis, Mo., they were first seen April 20; and at Paris, IIL, April 22. With the exception of two stragglers seen at Manhattan, Kans., April 21, no record of movement at this time was made in the country, west of the.Mississippi River. The birds rested until the pronounced warm wawe of the last few days of the month, and then moved forward. Records were received of its presence, April 28 and April 29, at Pe- oria, Aledo, and Hennepin, Ill.; Keokuk, Iowa; Glasgow, Mo., together with a note on its second arrival at Manhattan, Kans. The first was recorded May 1, at Reeds and Mount Carmel, Mo., and by both of the observers at Fayette, Mo., indicating that there was a special move- -meut in Missouri on that date. The Catbirds did not rest very long before the next movement. Their advance may be seen from the fol- lowing dates: They reached Richmond, Iowa, May 2; Mount Pleasant, Iowa, and Tampico, Ill., May 3; Chicago, Ill., Rockford, IIl., and Leeds Center, Wis., May 4. During the cold weather of the second week of May odd records were made at Grinnell and Waukon, Iowa; Delavan, Wis., and Lanesboro, Minn., where Catbirds were seen May 7 and May 8; on May 12 they were reported from Williamstown, Lowa; Rochester, 268 Minn., and Stoughton, Wis. Early birds had been seen at Lake City, Minn., May 3, and at Elk River, Minn., May 6. The regular advance did not reach thesé places until May 15, on which date it was reported also at Hastings and Minneapolis, Minn., and River Falls, New Rich- mend, and Green Bay, Wis. The next day (May 16) about twenty were seen at White Earth, Minn. During the cold period the bulk overtook the advance guard, so that by the middle of May the van and bulk were moving almost together. This is shown by the fact that while May 15 marked the arrival of the first at the above-named stations, enough more came the next night to make the species common May 16. May 20 they were recorded as arriving at Huron, Dak. No reports were received from the region between latitude 45° and latitude 49°, but May 25 and 26 they occupied the whole of Manitoba to latitude 50° 30’, In the fall of 1885 the last Catbird left Elk River, Minn., September 12; Des Moines, Iowa, September 18; and Mount Carmel, Mo., Sep- tember 10, At Saint Loais, Mo., they were numerous from September 16 to 26; the bulk left September 29, and the last followed October 6. Very late migrants were seen at Milwaukee, Wis., October 24, and al’ayette, Mo., November 20; while at Bonham, Tex., where they had been reported during the three previous winters, not a Catbird was seen during the winter of 1885-86. 705. Harporhynchus rufus (Linn.). [13.] Brown Thrasher. The Brown Thrasher is a common summer resident throughout the Mississippi Valley and Manitoba, aud winters in the Gulf States and southward. In 1884 reports upon its migration were received from 85 observers. The species is so easily recognized that it is not likely to be overlooked, but its movements on its first arrival are so stealthy and retired that it may be present for several days without being observed, unless the weather is fine. In the winter of 1883~84 it was reported as a winter resident at Waverly, Miss., Mermenton, La., and Abbe- ville, La., being abundant at the two last-mentioned places. At Cor- inth, Miss., a single bird was seen December 28, 1883, and January 10, 1884. ‘The observer adds that they were never seen there before during thirty years residence. They have been known to winter as far north as southern Illinois. The first record of its appearance north of Mis- sissippi and Louisiana in 1884 was made at Danville, Ill., March 15. This was probably a straggler. The first general movement took place about March 22. On that day a single male, in high plumage; but silent, appeared at Saint Louis. The following day three males were observed at their old stands, in song. The same day (March 23) it was reported from Odin and Carlinville, Il].; and April 1 from Hills- borough and Griggsville, Il. April 4 the bulk arrived at Reeds, Mo., and April 10 at Mount Carmel, Mo. April 12 the first arrived at Lin- wood, Nebr. Two days later the bulk reached Saint Louis, Mo. April 17 the first appeared at Manhattan, Kans., and April 19 at Coleta, Il. This date was the height of the season at Saint Louis, Mo., where the 269 number was swelled by the presence of both transients and summer so- journers. A decided northward impulse was observed during the next week. April 21 the first arrived at Richmond, Iowa; and April 26 at the following places: Polo, Il].; Des Moiues, Iowa; Iowa City, Iowa; Grand Junction, Iowa; and Hastings, Minn. April 27 the first was seen at Lanesboro, Minn.; April 28 at Lake Mills, Wis.; and April 30 at Red Wing and Elk River, Minn. On the same day the bulk arrived at Grand Junction, Iowa; Lanesboro, Minn.; and Manhattan, Kans. These movements show that the line of heaviest and earliest migration was along the Mississippi River. Thence it spread up the valleys of the rivers and streams tributary to it. Migration seemed to be at its height about the end of April. May 1 the first arrival was noted at Green Bay, Wis., and the balk arrived at Elk River, Minn. May 5 Brown Thrashers were seen at Vermillion, Dak.; May 13 at Huron, Dak.; and May 21 at Oak Point, Manitoba. Only one note of its breed- ing was recorded. This was at Saint Louis, Mo., where young were found as early as May 30. At Manhattan, Kans, they were building May 9. In the fall of 1884 the following records were received of the southe ward movements of the Brown Thrasher: At Williamstown, Iowa, the bulk left August 18, and the last August 29; at Unadilla, Nebr., the last was seen August 23; at Des Moines, Iowa, September 17. The bulk left Mount Carmel, Mo., September 20, and the last September 26. The first reached Gainesville, Tex., September 26. In the spring of 1885 no notes were contributed on its movements until it reached southern Illinois. It arrived at Shawneetown Mareh 27. At Saint Louis, Mo., the first came April 2, two days earlier than it was reported at Paris, Ill., to which place it was carried by a tre- mendous bird wave, which reached there the afternoon and evening of April 4, To the westward of Saint Louis the birds waited for the next warm wave, reaching Glasgow, in north central Missouri, April 6. In the Ozark Hills, in southwestern Missouri, they were reported as arriv- ing at Pierce City and Reeds April 4. Still farther west, in east central Kansas (at Richmond and Manhattan), they did not put in an appear- ance until April 15. The only station in the vicinity of the Mississippi River at which they were reported between latitude 39° and latitude 41° was Griggsville, lll., where they were scen April 11. As this date and locality coincided with the maximum of a warm wave, it may be supposed that this wave carried the van to latitude 40°. The next movement was quite regular. It began at Ferry and Mount Pleasant, Iowa, April 19; the next day extended to Iowa City, Iowa, and crossed the river to Aledo, Tampico, and Hennepin, LL; while the third day a great rush brought the birds to Des Moines, Coralville, Grin- nell, and Newton, Iowa, Rockford, Ill., and Lanesboro and Lake City, Minn. This was one of the most pronounced movements of the whole season of migration, and it was carried still farther forward on April 22 270 and April 23, by the arrival of Brown Thrashers at Milwaukee, Lake Mills, Leeds Center, Ripon, and Durand, Wis., and Minneapolis, Minn. At Elk River, Minn., the first was seen May 1. On the plains the ad- vance was about two weeks later. Linwood, Nebr., was reached April 24; Huron, Dak., May 15; and Shell River, Manitoba, May 23. In the fall of 1885 the last Brown Thrasher left Eik River, Minn., September 12; Des Moines, Iowa, September 16; Grinnell, Iowa, Sep- tember 28; and Mount Carmel, Mo., October 10. At Saint Louis, Mo., they were numerous from September 16 to 26; the bulk left September 29, and the last October 16. At Bonham, Tex., where they are com- mon winter residents, the first came September 19, and they had be- come common by November 19. 706. Harporhynchus longirostris (Lafr.). [13a.] Long-billed Thrasher. An inhabitant of eastern Mexico and the valley of the Lower Rio Grande in Texas, where it is an abundant resident (Merrill; Sennett). 707. Harporhynchus curvirostris (Swains.), [15.] Curve-billed Thrasher. The home of this species is on the tablelands of Mexico, and thence north to the valley of the Rio Grande River in Texas. It is a common resident on the Lower Rio Grande, and is found as high up as Eagle Pass, where it breeds abundantly. 713. Campylorhynchus brunneicapillus (Lafr.). [54.] Cactus Wren. In our district this species is found in western Texas only. At Eagle Pass it is resident, and began nest-building February 26, 1884. In the fall of 1885 three specimens were secured at San Angelo, Tex., which is a northern locality for the species. In May, 1886, Mr. Lloyd found young at Saragossa P. O., Tex., which is in approximately the same latitude as San Angelo, but farther west. He says that it is probably resident on the plains in Tom Green County. 715. Salpinctes obsoletus (Say). [58.] Rock Wren. The Rock Wren occurs from the Plains to the Pacific, and is supposed to breed throughout most of its range. A few notes concerning it were received from the western part of the district, and it is known that the species migrates principally west of the 99th meridian. It has been taken once in Decatur County, Iowa, and there is a record that a “Caiion Wren,” probably this species, was shot among the rocky bluffs of the river at Kansas City, Mo. In the western part of Kansas it is found at Ellis as a common summer resident. At San An- gelo, Tex., it was given merely as a winter resident, arriving from the North September 10, in 1883, and leaving May 10, in 1884. Some dis- tance southeast, near Boerne, a female was shot March 4, 1880 (Brown). 717. Catherpes mexicanus (Swains.). [59.] White-throated Wren. This Wren is resident in Mexico and southern Texas. 717a. Catherpes mexicanus conspersus Ridgw. [59a.] Cation Wren. The Cafion Wren inhabits the southwestern United States from west- 271 ern Texas and Colorado westward. During the winter of 1879-’80 Mr. N. C. Brown discovered about three pairs in a cafion on Cibalo Creek, near Boerne, Tex.; and Mr. William Lloyd found it common at Fort Davis, Tex. 718. Thryothorus ludovicianus (Lath.). [60.] Carolina Wren. An abundant resident in the southern portion of the Mississippi Val- ley. Its movements in migration are very slight, and are confined to the northern portion of its range, namely, southern Nebraska, southern Iowa, and northern Ilinois. The few individuals that find their way to these sections retire southward in winter, and a slight decrease in num- bers during the winter is also discernible south to about latitude 38°; below this there is no change. This species belongs more particularly to the East, being seldom found west of longitnde 99°, In Kansas, where it is resident, it is abundant in the eastern but rare in the west- ern part of the State (Goss). The form of the species once recognized as Berlandier’s Wren (Thry- othorus ludovicianus berlandieri), but not now considered distinct, occurs in southwestern Texas. It was somewhat common at San Angelo during the winter, and one or two were scen every few days until May 6. Ite probably breeds, though Mr. Lloyd has not yet found any nests. 719. Thryothorus bewickii (Aud.). [61.] Bewick’s Wren. The distribution of this species over the Mississippi Valley is very irregular. Abundant in some places and rarely or never seen in con- tiguous territory, it seems to be governed by fancy in the choice of a dwelling place. Like the Carolina Wren, it is not strictly a migratory species, but leaves the northern portions of its range and winters from southern Illinois southward. In summer it is exceedingly abundant in southern Indiana and some parts of Illinois, being the common “ House Wren” to the exclusion of Troglodytes aédon. The same is true of east- ern Texas, and of some places in Missouri. West and north of these States it is not common. It is not common in Kansas, and is rare in Nebraska. Dr. Hatch’s note for Minnesota, stating that it is “common in summer,” would better express the facts did it read: ‘‘Not uncom- mon during summer in a few localities in the southern part of the State.” Its limited migration is performed in the last week of March and the first few days of April. {n the spring of 1885, at Gainesville, Tex., the first Bewick’s Wren was reported March 6, and the next March 28. At Pierce City, Mo., the first was seen March 31. At Saint Louis the first was seen March 30, and the species became common the next day. 719b. Thryothorus bewickii bairdi (Salv.& Godm.). [61b.] Baird’s Wren; Texas Bewick’s Wren. An abundant resident in Texas, and not uncommon in southwestern Kansas (Goss). At Caddo, Ind. Ter., only 30 miles north of the Texas line, specimens of Bewick’s Wren killed in December, when the species 272 was most zommon, apparently were typical bewickii. It disappeared in the early spring, but the people of town said it would come again and be the House Wren of the summer. As the Texas form is known to be abundant only a few miles southward, it seems probable that the winter birds are typical bewickii and the summer birds bairdi. A change of res- idence on the part of the author prevented the exact determination of the matter. At Caddo, neither Troglodytes aédon nor its western sub- species has been found. Mr. Lloyd states that Baird’s Wren raises two broods in western Texas, where it is an abundant resident. 721. Troglodytes aédon Vieill. [63.] House Wren. The House Wren is a bird of the Eastern States, ranging west to the Mississippi Valley. In looking over the notes contributed on this species it bas been found necessary to cut out 35 per cent. as being of uncertain identity. The House Wren is so commonly confounded with the Winter Wren that the records of its movements are per- plexing and not very reliable. Information is needed concerning the northern limit of its winter range in the Southern States west of the Mississippi River. East of the Mississippi it is reported as regu- larly resident up to latitude 385°, and occasionally still farther north in heavy bottom lands. In migration, in the spring of 1884, it reached latitude 37° in Missouri the last week in March; latitude 38° 40/ in Missouri April 19; latitude 39° 19’ in Illinois April 25; and latitude 39° 12’ in Kansas April 24. After this the advance seems to have been very rapid, for the species arrived at latitude 46° 33’ in Minnesota May 3, and at Oak Point, Manitoba (latitude 50° 30’), near the limit of its northward journey, May17. There is quite a strong intimation that the wigration through eastern Illinois and Wisconsin took place from a week to ten days earlier than the movement in corresponding latitudes west of the Mississippi, but in the present uncertainty as to which species of Wren was actually seen no positive statement can be made. In the fall of 1884 the bulk of House Wrens left Des Moines, Iowa, August 28, and none were seen there after that date. At Shawnee- town, IIl., a single bird was reported as having been seen all winter. In the spring of 1885 the records of the House Wren and the Winter Wren in migration were hopelessly mixed. The two Wrens appear to have migrated more nearly at the same time than usual, thus increasing the confusion of the records. All that can be safely said of the House Wren is that it was one month (from April 17 to May 17) in passing from Saint Louis, Mo. (latitude 38° 40’), to Oak Point Manitoba (lati- tude 50° 30’), The A. O. U. Check-list gives the habitat of the typ- ical House Wren as “Eastern United States and Southern Canada, — west to Indiana and Louisiana.” The subspecies parkmanii is given as ranging in “ Western North America, from Texas, Illinois, Minnesota, and Manitoba westward; north to Great Slave Lake, south to Jalapa, Mexico, and Lower California.” According to these habitats, both of the localities mentioned, Saint Louis and Oak Point, belong to the 273 western subspecies, and the same would be true of most of the records received under the name of the House Wren. It will be noticed that in the notes for 1884 it is said that there is an intimation that migration in Illinois and Wisconsin was a week or ten days earlier than that west of the Mississippi River. The same thing, in astill greater degree, ap- pears in the notes for 1885, The records from eastern Illinois and Wis- consin, from such reliable observers as Mr. Balmer, Mr. Ingram, and a half dozen others, are fourteen days earlier than from corresponding latitudes in Missouri and Iowa. Now, if in these records for both years the House Wren and not the Winter Wren was the bird really seen, it fol- lows that there is a clearly marked difference in the times of migration of the eastern and western House Wrens. To fully determine this point the records of the observers in the district east of the Mississippi Val- ley would have to be consulted and a careful sc ries of observations made with reference to this particular point. The case is quite similar to that of the eastern and westein Meadcwlarks, and is well worthy of future consideration. Tn the fall of 1885 the last House Wren was reported from Grinnell, Towa, September 27; from Des Moines, Iowa, September 26, and from Saint Louis, Mo., September 29. The first one reached San Angelo, Tex: September 11. Dr. Agersborg states that both typical T. aédon and T. aédon parkmanit breed in southern Dakota. 721a. Troglodytes aédon parkmanii (Aud.). [63a.] Western House Wren; Park- man’s Wren. Parkman’s Wren is a bird of the Western States, coming east to the Mississippi Valley. - After what has been said of the eastern form but little remains to be said of the western. Its rangeina north and south direction is about the same as the foregoing, and the dates of its mi- gration are also much the same—possibly a little later. Concerning its eastward extension, it may be said to be common in western Texas, and it was found at Gainesville in north-central Texas in the spring of 1884. It is a common summer resident in Kansas, and is common in Ne. braska, Dakota, western Minnesota, and western Manitoba. It has been taken several times at Chicago, Ill. Thus its course of migration is seen to tend somewhat in a northeasterly direction. 722. Troglodytes hiemalis Vieill. [65.] [inicr Wren. Breeds from the Northern States northward. Mr. H. A. Kline tells us that it nests in the rubbish along the banks of a stream one mile west of Polo, Il., and Mr. Preston has found it asa not common breeder in central lowa. This Wren can endure cold many degrees below zero, and is found during the winter in much of the heavy timber south of latitude 39°, Most of the birds winter between latitude 34° and latitude 37°. In the spring of 1884 its migration took place a week or ten days earlier than in 1883, The migrants reached latitude 39° about March 20, and 7365—Bull 2 18 274 then paused until April 1. From April 5 to April 12 it spread over all the country north to latitude 45°, The last left Caddo, Ind. Ter., March 25; and Saint Louis, April 11. In the fall of 1884 the first Winter Wren appeared at Mount Carmel, Mo., September 13. After what has been said under the head ef the House Wren, it is searcely necessary to add that the records of the Winter Wren’s move- ments during the spring of 1885 were largely confused with those of that species. All of the notes, with one exception, were very late, and this exception came from northeastern Llinois, and probably refers to the eastern House Wren. In the fall of 1885 the only Winter Wren seen in fall migration at Elk River, Minon., was September 30. At Mount Carmel, Mo., one was seen October 19, while at Grinnell, Iowa, it was twice seen during the first week of November. 724. Cistothorus stellaris (Licht.). [63.] Short-billed Marsh Wren. The Short-billed Marsh Wren breeds abundantly in western Man- itoba, and occasionally throughout the southern part of its range, but in summer the bulk of the species is north of latitude 40°. Dr. Agers- borg has recorded it as a rare breeder in southeastern Dakota. In the Mississippi Valley it is not so common as the following species, and its winter home averages a little farther north. The notes indi- eate that it migrated about the same time as the Long-billed. In the spring of 1885 the first and only Short billed Marsh Wren seen at Saint Louis was observed April 28. At Fernwood, IIl., the first was recorded May 10, and at Elk River, Minn., May 16. In the fall of 1885 the last left Elk River, Minu., September 3. At Grinnell, Iowa, the first was seen October 22, and the last October 27. 725, Cistothorus palustris (Wils.). [67.] Long-billed Marsh Wren. Occurs throughout the Mississippi Valley from Manitoba to the Gulf, wintering in the Southern States, and occasionally in mild winters even in southern Illinois. It is a late migrant. In the spring of 1884 it reached Bllis, Kans., April 27, where it is a rare summer resident. Nearer the Mississippi River it arrived somewhat earlier, but it did not advance to latitude 45° till the middle of May. Few of the observers have noted this species, since its favorite haunts are in marshes, more or less inaccessible. In the spring of 1885 Stoughton, Ill, was the only station that sent a report on the spring wigration of the Long-billed Marsh Wren. It was first seen there May 12, and next May 14, at which date it be- came common. The species breeds throughout its range. It is a rare spring migrant in western Texas (Lloyd). In the fall of 1885 the first migrant appeared at Saint Louis, Mo., September 19, and the last was seen there October 6, At Emporia, Kans., the last was seen September 26, 275 726, Certhia familiaris americana (Bonap.). [55.] Brown Creeper. Breeds chiefly along our northern border. The migratory movements of this species are peculiar. Dr. Coues says that it is “almost station- ary,” aud yet there is probably no individual of the species that re- mains in the same latitude the whole year, while it is true that a few individuals may be found far north in winter and an equal number far south in suinmer. ‘The bulk of the species migrates with more or less regularity. In 18838 it was found wintering ‘in Indian Territory, Missouri, Kansas, southern Wisconsin, and “very rarely” in southern Dakota. In previous years it has been found wintering up to latitude 45°, but beyond that point none of the Mississippi Valley observers have noted if in winter. During cold weather it remains among the heaviest timber, and hence would be seen by very few of the observers, but during its migration it can be found almost anywhere. From the fact that a few individuals wiutered all along the Mississippi Valley, it is very difficult to trace its spring movements with accuracy. Dr. Coues implies that it breeds throughout its range, but instances of its breeding south of latitude 41° must be very rare. Indeed there is no such case recorded from the whole State of Illinois, and all observers south of latitude 41° agree in calling it either a winter resident or a transient visitor. Mr. T. M. Trippe, in a contribution on the “ Birds of Colorado,” which appeared in Coues’s *‘ Birds of the Northwest,” stated (p. 230): Abundant during the winter, from 7,000 feet up to 9,000 feet, and probably ranging considerably higher and lower. Breeds sparingly in the upper woods, within a few hundred feet of timber-line, Appears at Idaho late in the fall, and becomes very com- mon as soon as the weather becomes cold, great numbers coming in from other re- gions. There seems to be little doubt that the bulk of the species breeds in the heavy forests along our northern boundary, and for a considerable distance beyond. The spring migration in 1884 began about the middle of March, and was at its height from April 10 to April 20, at which date the species was found migrating over all the northern half of the Mis- sissippi Valley and in British America. It arrived at Oak Point, Mani- toba, April 17. The migration was completed south of Jatitude 45° about the 1st of May. Iu the fall of 1884 the Brown Creeper was reported ‘as reaching Elk River, Minnesota, September 25, where it was last seen October 17. It was first reported from Des Moines, Iowa, November 8; and last from Mount Carmel, Mo., September 21. In the spring of 1885 there was no regularity in the reports of the northward migration of the Brown Creeper. The records extend from April 1 at Saint Louis, Mo., to April 15 at Elk River, Minnesota. The last was seen at Saint Louis April 26, which is a later date than it was reported from any other station. In the fall of 1885 the nine records of migration received were irregu- 276 lar. They indicate that the height of migration in the upper half of the Mississippi Valley was about October 1. Mr. Lioyd states that in western Texas it is a “tolerably common winter visitor.” 727. Sitta carolinensis Lath. [51.] White-bellied Nuthatch. This non-migratory species belongs more particularly to the eastern two-thirds of the Mississippi Valley. The 97th meridian very nearly bounds its western range, and beyond this line it is only met with as a straggler. It has been found in western Kansas, aud was reported from San Angelo, Tex., as “resident but rare.” Only a few were seen at Caddo, Ind. Ter., and fewer still at Gainesville, Tex. 727a. Sitta carolinensis aculeata (Cass.). [51a.] Slender-billed Nuthatch. This western form of the White-bellied Nuthatch is partially migra- tory. Mr. Seton (now Thompson) gave it as “a rather rare summer resident in western Manitoba.” It occurs in the western part of our district, has been found in the timbered tracts of eastern Nebraska, and is a rare resident at Vermillion, in southeastern Dakota. Mr. Lloyd found it to be the prevailing form at Fort Davis, Tex., while at San Angelo, Tex., only the eastern form was noted. 728. Sitta canadensis Linn. [52.] Red-bellied Nuthatch. This is a truly migratory species, but our knowledge of its move- ments lacks precision. In the winter-time it is found throughout the district from the Gulf of Mexico to Minnesota. In summer the bulk passes beyond our northern border. It is rare in western Manitoba- It was reported in summer from Polo, in northern Illinois; and at New- ton, in central Iowa, it was recorded as a resident.* The few notes contributed upon its movements in the spring of 1884 indicate that its time of migration in the middle districts (between lati- tude 39° and latitude 42°) was during the last week in April and the first week in May. In the spring of 1885 the first Red-bellied’ Nuthatch was reported from Paris, ill., May 1. At La Porte City, Iowa, one was seen April 19. 729. Sitta pusilla Lath. [53.] Brown-headed Nuthatch. A bird of the southern portion of the Mississippi Valley and eastward; resident throughout its range. The most northern record in 1884 came from Newport, Ark. (latitude 35° 36’), but it has been found by Mr. Widmann as an accidental visitor at Saint Louis, and has been recorded from Ohio. 730. Sitta pygmza Vig. [54.] Pygmy Nuthatch. An inhabitant of the western United States and the mountainous districts of Mexico. According to Professor Aughey it has been found once in northern Nebraska, where it must be a rare straggler. *T am of opinion that these records need verification.—C. H. M. 277 731. Parus bicolor Linn. [(36.] Tufted Titmouse. A common resident throughout the southern half of the Mississippi Valley east of the plains; abundant in eastern Kansas. If this bird performs any migration, it does so merely from the more opeu country, which it inhabits in summer, to the nearest heavy timber. In the late fall itisa most noisy bird, but in winter the struggle for food gives it no time for “ petoing.” With the first sign of spring, however, it begins with redoubled energy and keeps the woods full of its clear whistle until after the young have left the nest. In the Mississippi Valley it is not common north of southern Iowa, but has been known to wander to Minnesota. At Caddo, Ind. Ter., it began to leave the bottom-lands March 3, and by March 25 was spread evenly over the country. Parus bicolor texensis Sennett. [—.] Texan Tufled Titmouse. An inhabitant of southern Texas. (For a description of this new Tit see the Auk, vol. iv, No. 1, Jan., 1887, pp. 29-30.) 732, Parus atricristatus Cass. [37.] Black-crested Titmouse. Dr. Coues, in his “ Birds of the Colorado Valley,” says of this spe- cies: “ Habitat, Valley of the Rio Grande and southward in Mexico, (p. 116). But the same year (1878) Mr. Ragsdale determined its range in the United States to be south from latitude 33° and west from longi- tude 98° 30’. Mr. Lloyd has ascertained that it is a tolerably common resident in Concho and Tom Green Counties, Tex., and thence to El Paso is the prevailing species. In April, 1878, its eggs were taken in Comal County, Tex., by Mr. W. H. Werden (Bull. Nutt. Ornith. Club, vol. Iv, 1879, p. 76); and Mr. N. C. Brown found it “a very abundant resident” at Boerne, Texas, in 1880. (Zbid., vol. VII, 1882, p. 35.) It is an abundant resident along the Lower Rio Grande (Merrill; Sen- nett). Parus atricristatus castaneifrons Sennett. [—.] Chestnut-fronted Titmouse. This new subspecies has been recently described by Mr. Sennett, from specimens taken in Bee County, in southern Texas (Auk, vol. iv, No. 1, Jan., 1887, pp. 28-29). 7 734. Parus wollweberi (Bonap.). [39.] Bridled Titmouse. The home of the Bridled Tit is in western Texas and thence westward. 735. Parus atricapillus Linn. [41.] Black-capped Chickadee. This Chickadee is found in the United States from western Iowa and. eastern Kansas eastward, and from southern Illinois northward. It has been claimed that it is not stationary, as has been generally supposed, but that there is a migratory movement each fall and spring, so that the speciés is not represented in winter at any station by the same in- dividuals which are found there in summer. Very little material has _ever been collected for the settlement of this point, and the field would be a fruitful one for some patient and painstaking observer. The only light furnished on the subject, by the record of 1884, came from Saint 278 Louis, where transient individuals were seen passing from March 20 to March 26.* Mr. Lloyd took one in spring migration in eastern Concho County, Tex. 735a. Parus atricapillus septentrionalis (Harris). [41la.] Long-tailed Chickadee. This is the western form of the preceding, and similar to it in habits. It is found as far east as Missouri, eastern Nebraska, and western Min- nesota along the Red River, thus slightly overlapping the hume of the Black-cap. Dr. Agersborg states that it is the only Chickadee found in southeastern Dakota, and Colonel Goss says it is common in western Kansas. In the South it has been found in Texas, where it was mixed with the southern Chickadee. Professor Lantz took a fine set of seven eggs April 17, at Manhattan, Kans., and the next day a set of the eggs of the Eastern form. 736. Parus carolinensis Aud. [42.] Carolina Chickadee. This is a Southern species, and is supposed to be a resident through- out its range, which extends southward from southern Illinois and cen- tral Missouri. It thus overlaps the range of the Black-capped Chicka- dee, and in southwestern Missouri (for example, at Pierce City) all three forms are found. In Concho County, Tex., Mr. Lloyd found it once in winter, and once in spring migration. It was previously ascer- tained to be a resident in Comal County, Tex. (Bull. Nutt. Ornith. Clab, vol. tv, 1879, p. 76); and is a common resident in eastern Texas (Nehr- ling). 740. Parus hudsonicus Forst. [45.] Hudsonian Chickadee. Breeds in British America and is a raré visitant to the northern parts of our district. It has been recorded from Illinois, Wisconsin, and Michigan. 744, Psaltriparus plumbeus Baird. [48.] JLead-colored Bush-Tit. Mr. William Lloyd has ascertained that this western Tit ranges east to our district. He saw an erratic flock of about twenty individuals at Fort Davis, Tex., during November, 1885. 746. Auriparus flaviceps (Sund.). (50.] Verdin; Yellow-headed Tit. The Verdin or Yellow-headed Tit has been known for years as a resi- dent of southern Texas. Its range extends from the valley of the lower Rio Grande westward to Lower California, and south to northeru Mexico, One of our observers, Mr. H. P. Attwater, has studied its habits at a place near the extreme northeastern limit of its range. He found it resident and quite common at San Antonio, Tex. (lat. 29°27’), where, during the summer of 1884, his party obtained about thirty skins and quite a number of nests and eggs. The nest, which is so large as to be out of all proportion to the size of the bird, is occupied all winter as a *There is no question whatever that this Chickadee is a migrant, however, limited its migrations may be. In the District of Columbia and neighboring portions of Maryland and Virginia it is a winter visitant, never remaining to breed.—C. H. M. 279 sleeping place. In journeying from San Antonio southwestward to the Rio Grande River, Mr. Attwater found these birds not numerous, but evenly distributed over all the country. 748. Regulus satrapa Licht. [33.] Golden-crowned Kinglet. A migrant in the Mississippi Valley, possibly a few breed in north- ern Minnesota. This species is much less numerous than the Ruby- crowned Kinglet, and is seldom seen in real flocks. It is, however, a wuch hardier bird, and winters over most of the United States south of latitude 40°, and a little farther north in the mountainous portions of the East. This of course means in suitable localities, which are heavily wooded valleys. Unlike the Ruby-crowned Kinglet, it is most numerous in the middle portion of its winter habitat, but few going as far south as the Gulf. Still Mr. Lloyd tells us that a few winter in Concho County, Tex., and that it is tolerably common there in fall migration. In southeastern Texas it is common in winter (Nehrling). The van does not start northward many days in advance of the Ruby-crowns, but the transit of the bulk is much quicker, and the last Golden-crown usually leaves a locality before the other species even becomes common. Leaving out of account the very few individuals which wintered there in 1883~84, the first migrants arrived at latitude 39° about April 1, and at latitude 45° about the middle of the month. The last left Texas before March 20, and a month later there were none to be found south of latitude 40°. Mr. Kline states that a few remain all summer in the thick swamps near Polo, Ill. (lat. 41° 58’), but that he has never suc- ceeded in finding their nests. In the spring of 1885 a Golden-crowned Kinglet was shot at Gaines- ville,.Tex., March 24. A bird, probably this species, had also been seen there three days earlier. At Paris, [ll., the first was seen March 30; at Saint Louis, Mo., March 31; Chicago, Ill., April 1; Delavan, Wis., April 2; Grinnell, Iowa, April 7; Ripon, Wis., April 10; and New Richmond, Wis., April14. The redons of “lasts” were gary inte lat The faites: was May 138, at Durand, Wis. In the fall of 1886 the record was quite regular. “Firsts” were seen at; Lanesboro, Minn., October 2; Iowa City, Iowa, October 3; Milwau- kee, Wis., October 4, and Saint Louis, Mo., October 14. The last at Lanesboro were seen October 18; at Milwaukee, October 26, and at Saint Louis, October 31. 749. Regulus calendula (Linn.). [30.] Ruby-crowned Kinglet. Breeds chiefly north of the United States, and winters from near our southern border southward. At one station only, namely, San Angelo, Tex. (latitude 31° 22’), was this species reported as a winter. resident in 1883~84. Careful search might have revealed it at a dozen more stations, for it has been known to winter in Kansas and in south- ern Illinois. At Caddo, Ind. Ter., the most diligent search failed to discover a single individual, although the Golden-crowned Kinglet was 280 common. Mr. Lloyd states that the Nueces cafion, in southwestern Texas, is the winter home of countless myriads of these birds, and that they leave very early in the spring, none having been seen after Marcu 9, 1884. At Caddo, Ind. Ter., about a hundred were seen March 25, showing that the first came a few days before. Farther east the migra- tion began about the middle of March, and proceeded without much regularity. April 1 found the birds at about latitude 39°, with a few stragglers a little beyond. Then the records become irregular, as if the small size of the birds allowed them to escape the notice of about half the observers until some days after their arrival. Perhaps the notes on the migration of this species will give a fair idea of the returns made by observers with reference to many of the smaller birds. From lati- tude 40° to latitude 41° 59! the dates of arrival are: April 19, 21; March 30, 31; April 17, 15, 20; from latitude 42° to latitude 43° 59’: April 22, 27, 17, 5,10, May 8; from latitude 44° to latitude 45° 59’: April 12, 21, May 11. Much of this apparent confusion can be explained by the dif- ferences in altitude and situation of the stations, while the opportuni- ties and experience of the observer must also be taken into account. The normal arrival of the species at latitude 42° appears to have been about April 15, and at latitude 45° April 20. May 5 it arrived at Port- age la Prairie, Manitoba. Many of the observers were deceived in regard to the time of arrival of the bulk of this species. It is true that the first arrival often con- sists of many individuals, and that others come within a day or two, so that the species appears to be common; but the arrival of the great multitude, the real bulk, does not take place till two or three weeks later. If at that time one of its favorite haunts is visited it is found everywhere. Though scarcely breeding south of latitude 45° in the Mississippi Valley, yet it was found in Texas as late as May 1, and in the middle districts even on May 15. On the plains, as usual, it was later in migrating, reaching Manhattan, Kans., April 30, and Vermill- ion, Dak., May 8. In the "fall of 1884, Ruby- drowned Kinglets first appeared at Des Moines, Iowa, September 27, and for the next two days were common; they then left as suddenly as they had come. They were reported as arriving at San Angelo, Tex., October 8. In the spring of 1885 the earliest record came from San Antonio, Tex., February 26, and the next from Gainesville, Tex., March 31. Saint Louis, Mo., was reached April 1; Paris, Il, April 4; Mount Car- mel, Mo., April 5; lowa City, Iowa, April 6; Grinnell, Iowa, April 6; and Lanesboro, Minn., April 9. Then there seems to have been a long pause, for nearly two weeks passed before any other records were made, and these later notes were too irregular for use. At Saint Louis, Mo., the bulk was present from April 17 to April 20, and the last was seen May 5. “Lasts” were reported from Manhattan, Kans., May 6; Des Moines, Iowa, May 8; Mount Carmel, Mo., May 10; Grinnell, Iowa, 281 May 9; Williamstown, Iowa, May 5; Waukon, Iowa, May 12; Durand, Wis., May 138; while on May 16 about two hundred Ruby-crowns were seen at White Earth, Minn. In the fall of 1885 the record was more regular than that for the spring migration. ‘Firsts? were seen September 27 at Grinnell, Lowa, and Mount Carmel, Mo. At Saint Louis, Mo., the first was seen Octo- ber 5; at Emporia, Kans., October 6; at Bonham, Tex., October 14, and at San Angelo, Tex., October 17. “Lasts” were reported at Grinnell, Towa, October 10; Iowa City, lowa, Uctober 10, and Mount Carmel, Mo., October 12. At Saint Louis, Mo., where they were most numerous October 10 and 11, the last was seen October 23. 751. Polioptila cerulea (Linn.). [27.] Blue-Gray Gnatcatcher. The southern half of the Mississippi Valley is the summer home of this species, and a few may linger in winter on our extreme southern border, but the bulk deserts the United States for a warmer climate. They have been known to occur in Minnesota, but very rarely. The most northern record received in 1884 was from Laporte City, Iowa (lat. 42°18’). Theit dispersion in the West is a little peculiar. In Kan- sas all the observers gave them as common in migration, but few re- maining to breed, while in Nebraska they were considered rather rare. Where, then, do these abundant migrants breed? Returning, it enters the eastern part of the Mississippi Valley in early - March, but in western Texas is somewhat later. in the spring of 1834 it was seen at latitude 35° April 1, and the middle of the month at latitude 39°. The fact that these birds were near their journey’s end did not oceasion any decrease in their speed, for they pushed right on, and in a few days (by April 28) had reached the limit of their north- ward journey in northern Illinois and central Iowa. In Texas there is a decided difference between their migration in the eastern and western parts of the State. At Gainesville, Tex., they ap- peared March 22, and more than a hundred were seen at Caddo, Ind. Ter., March 25. These two stations are near the valley of the Red River. Much farther south, in western Texas, they appeared later, ar- riving at San Angelo and Mason April 6 and 7. In the northern part of their range the species may be considered as having completed its mnigration aud settled down to summer work about May: 10. Tn the fall of 1884 the bulk of Blue-gray Gnatcatchers was reported as leaving Des Moines, Iowa, August 26, and the last, three days later. The last was reported from Mount Carmel, Mo., September 6, and from San Angelo, Tex., October 5. In the spring of 1885 it arrived at San Angelo, Tex., March 15; Gainesville, Tex., March 23; Houma, La., March 31; Corinth, Miss., April 7, and Saint Louis, Mo., April 8. An early migrant was seen'at Peoria, Ill., April 13. The bulk reached Saint Louis, Mo., April 17, aud the first was reported from Paris, Ill., the sameday. April 18 they were seen at Emporia and Manhattan, in Kansas. Between April 20 282 and April 23, they appeared at Des Moines, Newton, and Grinnell, in Iowa. At New Richmond, Wis., a locality far north of the usual range of the species, it was reported May 18. In the fall of 1885 the last was seen at Grinnell, Iowa, September 26; and at Saint Louis, Mo., September 25. None were seen at Bonham, Tex., after September 1. 752. Polioptila plumbea Baird. [28.] Plumbeous Gnatcatcher. The home of this Gnatcatcher is in southern Texas and thence west- ward to Lower California. 754. Myadestes townsendii (Aud.). [25.] Townsend’s Solitaire. A rare stranger from the western United States. The only accounts of it in the Mississippi district refer to its ocvasional occurrence in win- ter. Prof. Aughey saw one on the Niobrara River in Nebraska, in 1877; January 17, 1880, Mr. Powell took a fine male at Alda, Nebr.; and later Mr. Hall saw it in southeastern Nebraska. Col. N. S. Goss gives it as ‘“‘an occasional fall and winter visitant in western Kansas,” where he saw ten and killed four in October, 1883. One was killed at Waukegan, Ill., December 16, 1875 (Nelson). Some of the most important of Mr. Lloyd’s many ornithological discoveries in western Texas refer to Town- send’s Solitaire. He not only determined its occurrence there in winter, by securing three specimens, but in May, 1886, he found its nest at Saragossa. It breeds in the Black Hills of Dakota. 755. Turdus mustelinus Gmel. [1.] Wood Thrush. The several Wood Thrushes (members of the subgenus Hylocichla) are so commonly and constantly confounded with one another by all but the practiced ornithologist, that no more hopeless task is encountered in the whole study of migration than that of attempting to determine which species were actually seen by each observer. Many notes, be- lieved by the observers to relate to the present species, evidently refer to the Hermit Thrush (Turdus pallasii), which is the earliest member of this group to migrate, and in other cases it is probable that the bird actually seen was the Olive-backed Thrush (Turdus. swainsonii), The Wood Thrush is a common breeder in the middle belt of the Mississippi Valley. It becomes rare toward our northern boundary. The first au- thentic record of the Wood Thrush in 1884 came from Saint Louis, Mo., where a single one was noted April 19. It was not seen again for a week, but April 26 the bulk of males appeared at Saint Louis, and soon after it began to be reported from more northern points. On the last day of April it was noted in latitude 39° 19 in Illinois, latitude 38° 45’ in Missouri, and latitude 39° 12’ in Kansas, showing that on that date the line of advance was pretty nearly coincident with the 39th parallel. The normal advance seems to have reached latitude 41° May 5, and the territory between latitude 42° and latitude 43° May 7 and 8. In Wisconsin it was observed at latitude 43° 43’ May 12, but in Minnesota at about the same latitude none were seen until May 283 17. There are other records from farther north, but it seems probable that they belong to the Hermit Thrush. It was reported by Mr. Nash from Portage la Prairie, Manitoba, though it is very scarce in that region. The records are too indefinite to admit of tracing the move- ments of the bulk. The species breeds throughout its range in the district, and winters beyond our border. Dr. Agersborg states that it is a rare summer resident in southeastern Dakota, and Colonel Goss records it as abundant in eastern Kansas. In the fall of 1884, at Des Moines, Iowa, the last Wood Thrush was seen August 25. At Mount Carmel, Mo., the bulk left September 1, and the last was seen September 14. In the spring of 1885 the following complete records of the movements of the four species of Thrushes most commonly confounded were re- ceived, and may be of use as a table of reference. Mr. Widmann’s record at Saint Louis was as follows: Hermit Thrush. First, April 1; bulk present from April 6 to April 18; last, April 24, Olive-backed Thrush. First, April 17; bulk present from May 4 to May 6; last, May 20. Wilson’s Thrush. First, April 22; bulk present from May 5 to May 12; last, May 12. Wood Thrush. First, April 19; bulk came April 28; remains to breed. In the spring of 1884 the movements of these species at Saint Louis were as follows: Hermit Thrush. First, April 1; bulk present from April 14 to April 19; last, April 28. Olive-backed Thrush. First, April 26; bulk present from April 29 to May 12; last, May 26. Wilson's Thrush, First, April 29; never common; last, May 21. Wood Thrush. First, April 19; bulk came April 26. In the spring of 1883 the record was: Hermit Thrush. First not noted; bulk present April 10 to April 12; last, April 13. Olive-backed Thrush. First, April 26; bulk present from May 2 to May 18; last, May 24. Wilson’s Thrush. First not noted; bulk present from May 15 to May 17°. last, May 21. At Jefferson, Wis., in the spring of 1883, I made the following rec- ord: Hermit Thrush. First, April 4; bulk present from April 20 to May 6; last, May 10. Olive-backed Thrush. Second seen May 3; bulk present from May 12 to May 24; last, May 31. Wilson's Thrush, First, May 7; bulk present from May 12 to May 24; last, May 30. Wood Thrush. First, May 10; bulk came May 17. These are the only complete records received. From them it will! be seen that although the exact dates are somewhat variable, the relative t 284 movements of the first three species remain the same for the three years and in the two widely separated localities, while the Wood Tirnsh shows great constancy in the time of its arrival at Saint Louis, without regard to the weather. The records of the migration of the Wood Thrush in the spring of 1885 fell between April 19, at Saint Louis, Mo., and May 18, at Lanes- boro, Minn. Tn the fall of 1885, at Grinnell, Iowa, the last was seen September 16, and at Saint Louis, Mo., September 26. 756. Turdus fuscescens Steph. [2.] Wilson's Thrush. This is rather a retired bird and one not often noticed in its late and hurried migration. It winters principally south of the United States, though a few stay in the Gulf States and Florida; hence it has a long journey to perform before reaching its breeding grounds in the nortb- ern United States and British America. In the spring of 1884 few records were made of its movements, and none whatever of its first ap- pearance along our southern border. No uotes were contributed from any locality south of Saint Louis, Mo., where two birds arrived April 29. Four birds, the highest number seen in one day, were recorded May 17, and May 21 the last one left, but managed to sing a little before its departure. A little farther up the river, at Burlington, Iowa, the first was noticed May 5, though one had been seen at Chicago, IIl., two days previcusly. May 11 and May 12 it reached West De Pere, Wis., and Lanesboro, Minn. A week later (May 18) it reached Oak Point, Manitoba. It breeds abundantly in Manitoba and occasionally in the Northern States, sometimes as far south as northern Illinois and Iowa. Mr. Kline took two sets of eggs at Polo, IIL, during the season of 1883; Dr. Agersborg has found it breeding at Vermillion, in southeastern Dakota, and its nest and eggs have been taken at Grinnell, Iowa. In the spring of 1885 the notes on Wilson’s Thrush were more regu- lar than those on the other species of Wood Thrushes. At Saint Louis, Mo., and Paris, Il., the first were reported April 22. From May 5 to May 9 they were noted at Mount Carmel, Mo., Iowa City, Iowa, Grin- nell, Iowa, Lanesboro and Lake City, Miun., and Durand, Wis. May 13 they appeared at River Falls, Wis., and May 16 I saw a single bird near White Earth, Minn. 756a. Turdus fuscescens salicicolus (Ridgw.). [—]. Willow Thrush. This western form of Wilson’s Thrush was described by Mr. Ridgway from the Rocky Mountain region of the United States. It was taken by Coues on the Souris River, along our northern boundary, and an accidental straggler came to Chicago, Ill., where it was taken Septem- ver 16, 1877, by Mr. H. K. Coale. The specimen was identified by Mr. Ridgway. Recently it has been killed in Cook County, Tex., by Mr. Ragsdale. Specimens were taken at Devil’s Lake and Pembina, Dak., by Mr. Vernon Bailey, in the summer of 1887, 285 757. Turdus aliciz Baird. [3.] Gray-cheeked Thrush. Alicé’s Thrush winters south and breeds north of our borders. But few notes were contributed on its movements, because few observers distinguish it from the Olive-backed Thrush. It is a common migrant in western Manitoba. The records received for 1884 can not be consid- ered as very trustworthy since they give its appearance at about the same date (May 7 and May 8) over the region from latitude 38° 40’, in Missouri, to latitude 42° 56’, in Dakota, and latitude 44° 32’, in Minue- sota. At Saint Louis the record reads: May 7, first; May 16, bulk; May 25, last. Thus its transit was more rapid than that of the Olive- backed, which arrived earlier and remained later. In the spring of 1885 the Gray-cheeked Thrush was first seen at Gaines- ville, Tex., May 9. At Saint Louis, Mo., the first was seen April 24, and the last May 25. At Paris, Ill., it was first seen April 15; at Des Moines, Iowa, May 8 (where it remained only three days); and at Lanes- boro, Minn., May 15. In Kansas it is a rare migrant (Goss). 758 a. Turdus ustulatus swainsonii (Caban.). [4a.] Olive-backed Thrush. A tolerably common summer resident from Manitoba northward. In tracing this species along the three routes of migration in the Mississippi Valley, it is found that the most eastern is the earliest and the most western the latest. In the spring of 1884, at Danville, Ill., the first came April 25, and it passed north to latitude 41° 57’ as early at least as April 28. Along the middle route, just west of the Mississippi River, the first was reported from latitude 38° 40’, in Missouri, April 26, and the bulk April 29. Farther up the river, they came to latitude 43° 4’, in Minne- sota, May 10, and to Minneapolis (lat.45°) May 17. Farther west, the bulk came to Manhattan, Kans. (lat. 39° 12’), May 13, were abundant for two days, and then suddenly disappeared. Mr. Widmann furnished a very full record fram Saint Louis, which is as follows: April 26, first; April 29, bulk arrived (small dark birds); May 5, height of the sea- son (song often heard, the birds chasing each other as if mating); May 9, bulk con- tinued present, dark birds; May 11, arrival of great numbers (lighter birds, probably one year old); May 13, the bulk of the species departed; May 26, last. This species winters south of our border, and breeds principally in British America, but occasionally has been found nesting as far south as northern Illinois. At Grinnell, Iowa, its nest and eggs have been taken, and toward the latter part of the season the young are fre- quently seen with the parents. In the spring of 1885 but few notes were contributed concerning the movements of the Olive-backed Thrush. The whole record from Saint Louis is as follows: “First, April 17; second, April 20; increase, April 22; arrival of bulk, May 4; most numerons, May 5; departure of bulk, May 6; last, May 20.” At Gainesville, Tex., the last was seen May 19, At Manhattan, Kans., the first was seen May 12 and the last May 16. At White Earth, Minon., May 16, I saw about thirty of these birds. 286 In the fall of 1885 the first were reported from River Falls, Wis., September 5. It isa rare fall migrant in Tom Green County, Tex. (Lloyd). 759. Turdus aonalaschke Gmel. [5.] Dwarf Hermit Thrush. The true home.of the Dwarf Hermit Thrush is in the Pacific coast region. During migration it passes east to Nevada and Atizona, and recently Mr. Lloyd has discovered it in Concho and Tom Green Counties, Tex., where it is a tolerably common fall migrant. He states that he has seen it every day from September 20 to October 10. 759a. Turdus aonalaschke auduboni (Baird). [ia.] Rocky Mountain Hermit Thrush. This western species was first found within our district by Mr. N. C. Brown, who procured it at Boerne, Tex. More recently Mr. Lloyd has taken two specimens at San Angelo, Tex., and Mr. Ragsdale has ex- tended its range by securing specimens at Gainesville, Tex. Mr. Lloyd’s later researches have determined that this form winters near San Angelo, and that it is a tolerably common spring migrant in Tom Green County, Tex. At Gainesville, the first was seen March 20. 759b. Turdus aonalaschke pallasii (Caban.). [5b.] Hermit Thrush. A common migrant in the Mississippi Valley, breeding in the north- ern and wintering in the southern part. The cold of winter has less effect upon this species than upon any of its brethren. It docs not mind moderate cold, but dislikes snow and usually manages to keep just south of the line where snow remains on the ground for weeks at a time. Sometimes, of course, it is caught in a snow-storm, but when this happens it seeks a thick covert and endures it. The heavy under- growth of the Mississippi bottom lands in southern Illinois offers a favorite wintering place for Hermit Thrushes, but the extreme weather of January, 1884, proved too severe for them and they left for a warmer climate. At Caddo, Ind. Ter., they remained the whole winter, but their habits were peculiar. In the May-day of their lives at the North they are shy, restless birds, ever watching for a tempting morsel, or from a low branch uttering their clear, liquid, and far-reaching notes. But in winter, in Indian Territory, they acted ‘as if life was a burden; insensible to their surroundings, they sat stupid and silent except for a short unmusical “chick,” and allowed one to approach within a few feet; if disturbed they moved but a short distance. The bulk of the species began to come from the southin the early part of March, but it is impossible to trace their movements from the notes contributed by observers. No bird has a more mixed and contradictory record, to say nothing of the many times it is confounded with the Brown Thrush and the Olive-backed. It is probable that the larger part of the notes are true, and indicate that the species is very erratic in its northward journey. The facts seem to show that during the great migration movements of the latter half of March, single individuals were scat- 287 tered over much of the Mississippi Valley to latitude 44°. But these individuals must be considered as forerunners, for the regular occupa- tion of this territory did not take place till nearly a month later. The regular migration began April 1, at latitude 39°, and by the beginning of May had advanced irregularly to latitude 45°, During the last week of April and the first part of May, the last of these birds left the lower part of this territory and soon reached their breeding grounds. Com- paratively few instances have been recorded of the breeding of the Hermit Thrush within the Mississippi Valley. Outside of the mount- ains of Colorado the most southern breeding point on record is Alda, Nebr. (Lat. 40° 53’), from which place Mr. F, W. Powell writes that - he found no nest, but saw the old birds feeding young which were too small to fly. At Grinnell, Iowa, the nest was found and identified by seeing the bird upon it. The nest and eggs are now in the Iowa Col- lege at Grinnell. At Des Moines, Iowa, they have been seen in the breeding season, but no nest has been found. In the spring of 1885 Hermit Thrushes came to Saint Louis, Mo., the 1st day of April, and during the rest of the week were noted from Paris, Aledo, and Chicago, Ill. Another advance took place April 15 to April 18, bringing them to Newton, Iowa, and Grinnell, Iowa, Hen- nepin, Ill, and Clinton, Wis. North of these places the records were unsatisfactory. The only “lasts” reported were from Saint Louis, April 24, and Chicago, May 5. Tn the fall of 1885 the first was observed at Saint Louis, Mo., Octo- ber 5; the bulk was present October 9; and the last was seen October 11. At Lanesboro, Minn., the last was noted October 10. In the eastern part of Concho County, Tex., Mr. Lloyd took one in spring migration. 761. Merula migratoria (Linn.). [7] -4dmerican Robin. The Robin is a common summer resident in Manitoba and throughout the Mississippi Valley except in the extreme southern portion. In winter it is abundant in Louisiana and in eastern and southern Texas, it also winters irregularly over most of its United States range. It seems to be the best known bird in the Mississippi Valley, and many more notes were contributed on it than on apy other species. It should be possible, therefore, to determine its movements with considerable accuracy. All through December, 1883, it was found in abundance throughout southern Dlinois, Missouri, and Kansas, but the extreme cold of the first week in January, 1884, drove it farther south into its real winter home. During the larger part of this month the bulk of the Robins (probably even $0 per cent. of them) were south of the parallel of 379, This is south of the usual winter limit of the species, the north- ern boundary for ordinary winters being about latitude 39°. It must not be supposed, however, that Robins never spend the winter farther north. The fact has been repeatedly demonstrated that nature has be- stowed on them strong constitutions, so that if food is plenty they can 288 withstand severe cold. Every year some of the northern observers re- port Robins wintering about their stations, and the winter of 188384 was no exception. One was seen, January 1, in northwestern Indiana; another, January 11, at Vermillion, Dak., and finally, at Hastings, Minn., 500 miles from his brethren, “one was seen Devember 28, 1883, with a flock of Pine Grosbeaks (Pinicola enucleator), apparently at home and determined to spend the winter. It was seen repeatedly, and actually remained till spring with the same flock of Grosbeaks.” The distribution of the Robin in its winter home depends entirely on the food supply ; where food is plenty, there the Robin remains, though observers a few miles away may not see one all winter. At Manhat- tan, Kans., berries are abundant, and during the winter of 1883-’84, as in previous years, flocks of five hundred or more individuals were con- stantly seen, while observers at stations but a short distance away re- ported no Robins from December until February. Manhattan, Kans., is the most northern station at which flocks of Robins remained during the winter. So far as can be learned, but few wintered in Indian Ter- ritory, nor did northern Texas fare much better; but they were reported as wintering in immense numbers along 300 miles of the cafion of the Nueces River in southwestern Texas. In Concho and Tom Green Coun- ties Mr. Lloyd states that they are tolerably common in spring and fall, and that a few winter in the river bottoms. They were reported from all the Southern States, at some points as abundant, at others as rare. In the early spring of 1884, as if disliking winter quarters, the Robins pushed north at the first breath of warm weather. Regardless of the certainty of being overtaken by cold, they hurried on, and trom Janu- ary 31 to February 3 occupied all the country from which they had been driven by the low temperature of the first of the year. This movement was confined to comparatively few individuals, and while the scouts had advanced to latitude 39°, or even a little farther north—single birds having been seen at Burlington, Iowa, (lat. 40° 50’) and at Lake Mills, Wis. (lat. 43° 06/)—the main body still remained in camp three or four hundred miles to the south. Then followed a whole month of waiting, during which time adventurous birds pressed northward, only to be driven back by snow and ice; nor was the real advance commenced until March 9. From that date until they had passed our northern boundary their advance was constant and more or less uniform. The regular advance of the van appears to have been as follows: From March 9 to 15 they spread over Illinois and eastern Nebraska to lati. tude 41° 51’; March 16, there was a slight advance in Iowa; March 17 and 18, no record; March 19 and 20 an advance to latitude 43° in Towa, Illinois, and Wisconsin, but not in Nebraska; March 21, a sud- den spreading over Wisconsin to latitude 459°. By March 24 the rest of the stations in Wisconsin had reported, and an equal advance had taken place in Minnesota, so that by this date the van was at latitude 45° along the whole line. North of this all the 289 stations are in the valley of the Red River of the North. In this valley the first arrivals reached latitude 479 April 3, and just one week later appeared at Oak Point, Manitoba (lat. 50° 30’). The fact that the spriug migration on the Western plains in 1884 was several days behind the migration in the same latitude farther east is clearly shown by the record of the Robin. At Ellis, Kans, (lat. 38° 55’), the first arrived March 21, but in Illinois it reached that latitude six weeks earlier. At Menoken, Dak. (lat. 46° 58’), it did rot arrive until April 29, while at Frazee City, Minn. (lat. 46° 33’), it arrived April 3; and at Larimore, Dak. (lat. 47° 52’), the high, bleak situation answers to a western posi- tion, and the Robins did not come until Apvril 21. The bulk of the species traveled much behind these advance guards in the lower part of the course, but moving faster than the scouts, by the time it reached the end of the march was but a few days in the rear. The bulk reached latitude 39° between March 12 and 17; then moved to latitude 43° March 23 and 24; to latitude 45° 30/ by Mareh 27 and 28; to latitude 47° April 5, and 0 Portage la Prairie, Manitoba, April 20. From the few scattering notes on the subject, we may guess that the bulk left latitude 35° March 7, Jatitude 37° March 25, latitude 39° March 31, and latitude 41° April 10. By the middle of April, in all the country south of latitude 43°, all Robins had left those places where they did not intend to breed, and at the other places had settled down to summer numbers. This is true not oniy of the Robin, but also of all those species whose records are sufficiently voluminous to afford a fair guide to their movements. This overtaking of the van by the rear may be explained in either of two ways, and it is probable that both causes have some effect. The individuals forming the van always con- sist of old birds, and these arriving at the place where they nested the previous year stop to breed, leaving the advance to be made by those behind, giving the mais body a chance to come close to the van; and, secondly, while the van is being constantly retarded by storms and cold, the rear travels in more settled weather and would naturally move faster. In the fall of 1884 the bulk of Robins left Elk River, Minn., Septem- ber 27, and the last was seen there November 7. At Hastings, Minn., none were seen after September 29. At Des Moines, Iowa, the bulk was recorded as leaving October 25, and at Mount Carmel, Mo., October 15. As already noted, many straggling Robins remain during the win- ter in sheltered localities much farther north than the regular winter bome of the species. At Manhattan, Kans., during the winter of 1884— 85, they were as abundant as usual, while a few were noted at various points for the next 200 miles southward. A single bird was seen at Morning Sun, Iowa, February 6. One remained at Newton, Iowa, all winter; at La Porte City, Iowa, they were common all winter, and even as far north as Hastings, Minn., 400 miles beyond its ordinary winter range, two birds were seen February 27. These may have been migrants 7365 Bull 2——19 290 ; a month ahead of their fellows (the next individuals of which were seen April 1), but it is more probable that they had wintered in that vicinity, as the neighboring bluffs along the Mississippi River furnish numerous well-sheltered spots, suitable for winter quarters. Mr, Alex- ander Scougal, of Sioux City, Iowa, sent the following interesting note: Among our winter birds there is one in particular which I wish to mention. It is the male Robin. Hardly a person will believe that there is 2 Robin in the State dur- ing the winter; but on December 23, 1883, I shot a male Robin but took no particular notice of it except to skin it. Last December (1884), during the holidays, I took my gun and started for a dense thicket, almost impenetrable by man or dog. There Isaw a number of Robins, and shot three. One of them was wing-tipped and when caught beyan to call, and immediately there were thirty-four Robins sitting around me, wak- ing noise enough to deafen one. I held the one in my hand fora Jong time so I could look at the rest; all of them were male birds; not a female could be seen. I found a house in the woods and asked the man about them. He informed me that they had been there all winter, but he was not able to distinguish males from females. I can not say positively that the female does not stay here in the winter, but I never have seen one nor heard of any here during that season;.so I think it must be rarely if ever seen. The day I saw the birds was December 27, and the temperature was 22° below zero. Again, January 2, 1885, I was there and saw the Robins a second time; it was then 17° below zero. I found in their stomachs wild grapes and seeds from a small bush (probably Symphoricarpus). The trees in that part of the woods were covered to their top with grape-vines, and many other vines grew underneath. The bir.ls were in good condition, and seemed as lively asin midsummer. Hence it would seem that these old birds, being the last to migrate, do not go so far south asthe rest of their species, but get into these dense thickets and are unnoticed by most people, until with the first warm weather they fly out into the open fields. The first day or two of February were warm, the mercury rising to 46° above zero, and these Robins were seen by a good many people in the city. A cry went around, ‘‘ Spring is coming, we have seen a Robin.” But February 5 cold weather returned, and now (February 16) the thermometer ranges from eight to fourteen degrees below zero. The people wonder where the Robins have gone, but if they would go to the dense thickets of Walker’s Island, on the Nebraska side of the river, they could find the same Robins as lively as ever. The same warm wave of Tebruary 2, just spoken of by Mr. Scougal, caused Robins to appear at Vermillion, Dak., a few miles northwest of Sioux City. A large flock was seen at the same place February 7. From points south of latitude 38° records of “firsts” can hardly be taken as necessarily indicating northward migration; but the dates given when the Robins became common show when the general north. ward movement began. In the spring of 1885 true migration seems to have commenced during the last two days of February and the first two days of March. Robius were not marked “common” before March 3 at any station north of lat- itude 39° with the exception of Glasgow, Mo., where they were so re- corded February 25. Out of about twenty species of the most common birds which had been studied before this bird was taken up, there was not one whose record could compare in irregularity with that of the Robin. It is utterly impossible to find any regular movement from the notes for the first three weeks in March. It may be supposed that something like this occurred: That during the first week of March the van moved 291 from latitude 39° to latitude 41°, in Missouri, Illinois, Iowa, and Ne- braska; that during the next two weeks of cold, freezing weather, lit- tle, if any, general advance was made, but that enough adventurous birds pressed forward to thoroughly confuse the record. During the two weeks from Mareh 7 to 21, most of the Robins abandoned winter quarters and appeared in new localities, which caused them to be re- corded as common throughout the Mississippi Valley south of the par- allel of 39°. On the night of March 21 the weather began to moderate and the following records of “ firsts” were made during the progress of the warm wave which followed: Robins were reported at Chicago, IIl., aud Milwaukee, Wis., March 22; Delavan, Wis., and Waukon, Iowa, March 23; Stoughton and Leeds Centre, Wis., and Rochester and Excel- sior, Minn., March 26. During the last two days of March and the first day of April, countless thousands of birds were moving in the Upper Mississippi Valley. Among them the Robin was not a small factor, and its arrival was noted in northern and northwestern Iowa at Williams- town, Sioux City, and Emmetsburgh; at Hastings in eastern Minnesota; at Heron Lake in southwestern Minnesota, and at Durand, Luck, New Cassel, and Green Bay, Wis. Just north of these places the following line of stations reported the first April 3 and 4: Grand View and Huron, Dak.; Minneapolis (two observers), Fridley and Elk River, Minn.; and Menoksn, Dak., (April 5). A 25-mile ride at White Earth, Minn., found the country quite well sprinkled with small flocks, more than two hun- dred in all being seen, where all the previous spring not a Robin had been found. Two days later the first Robin made its appearance at Oak Point, Manitoba, where the species was marked as common, April 9. These were probably early birds, since the other records for Mani- toba are Shell River, April 13; Two Rivers, April 16; and Ossowo, April 18, and it was not considered common at any of these places before April 20. The whole record from Saint Louis is as follows: March 2, first, a summer sojourner at its stand; March 3, small troops of transients on the wing; March 5, first female at stand; March 10 to 14, the bulk of the sammer sojourners arrived at their stands, and many transients passed in flocks; March 26 to April 2, the most con- spicuous songster; April 2, the bulk of transients had gone north, light- colored troops still lingered; April 11 to 16, parties of transients were still with us; April 17, last flock seen. Col. G. B. Brackett writes from Denmark, Iowa, that about the mid- die of April, for the last three years, immense flocks of Robins, num- bering many thousands, have come to roost at night in the evergreens on his premises. They usually remained about two weeks. In the fall of 1885, at Ossowo, Manitoba, the last Robin was seen Octo- ber 20; at Elk River, Minn., October 21; River Falls, Wis., October 29; Lanesboro, Minn., November 3; Milwaukee, Wis., November 11; Iowa City, Iowa, October 26; Des Moines, Iowa, October 24; Fernwood, Ill, November 21; Fayette, Mo., October 28, and Mount Carmel, Mo., 292 October 18. At Saint Louis, Mo., the first large flocks going south were noted September 9; from October 5 to 27 Robins were numerous; the last flock was seen October 30, and the last transient November 11. At Bouham, Tex., the first migrant came in October; the next was seen October 28, and they had become common by November. None were noted at Gainesville, Tex., until November 11. 761a. Mervla migratoria propinqua Ridgw. [7a.] Western Robin. October 12, 1883, Colonel Goss killed two out of a flock of seven at Wallace, Kans.; and Mr. Lloyd found a single flock in winter at San Angelo, in southwestern Texas. Mr. Lloyd says they are abundant in winter west of Tom Green County in Texas. 766. Sialia sialis (Linn.). [22.] Bluebird. The Bluebird breeds from the Gulf of Mexico northward to southern Manitoba. It is another familiar bird whose coming each spring is eagerly looked for, and whose movements are closely watched through the summer. Over the southern part of the United States his admirers are denied the pleasure of looking for his arrival, for he remains through- out the year. Hardy by nature, and capable of adapting himself to the food of the season, he remains at his post winter and summer. Orni- thologists claim that these winter birds are not the same individuals which are seen in summer, but that the summer birds have moved south- ward and their places have been supplied by arrivals from the north. This of course is generally true, and yet it is also a fact that from lati- tude 37° southward there are occasionally Bluebirds which keep their summer stations all through the winter, and it is not safe te say that none do so even up to latitude 39°. While its winter distribution is quite similar to the Robin’s, and governed likewise by the food supply rather than the temperature, yet the average winter range of the Blue- bird is a little more to the north, and it is as plentiful at latitude 39° as the Robin is at latitude 37°, Mr. Widmann contributed the following note from Saint Louis, Mo.: In rough weather they spend much of the time in their holes, that is, Woodpeckers" holes, which they enlarge for their own use as shelters and roosting places. Novem- ber 30 (1883) I watched a pair, when the female repeatedly entered the hole, brought out each time a bit of dead wood and reached it to the male, who carried it off a few yards and dropped it. It is fair to conclude that this pair intended to pass the winter at that locality. Toward the western part of the Mississippi district the species is not common, giving place to the Rocky Mountain Bluebird (Sialia arctica). It is not abundant much west of longitude 97°. Immense numbers were reported in winter from southwestern Texas; and these must migrate largely to the northeast. Mr. Lloyd says the species is resident in portions of Concho County, Tex. Throughout the winter of 1883-84 Bluebirds remained at suitable places between latitude 37° and latitude 39°, but were driven from less favorable localities by the severe weather of January 1. They returned 293 with the first warm wave the last of the month, and by February 1 the van approximated quite closely to the parallel of 39°. Here it came to a fall stop, and made no advance until March 9, There were only five records of Bluebirds north of latitude 39° before March 9, and all these ‘were from stations near large rivers. Starting then at latitude 39° on March 9, when the warm south wind was felt, the Bluebirds practically completed their migration before the 1st of April. To be sure, a few individuals were moving north during April and May, but the great bulk of the species stopped between latitude 45° and latitude 469°, and those which went farther north might almost be called stragglers. The impetuosity of their migration was checked, and they moved in small companies, seldom of more than a pair or two, slowly idling along as if undecided where to stop. During March their progress was as follows: By March 16 they had reached latitude 429, by March 22 lati- tude 43° 30’, and by March 24 latitude 45°. There is no plainer and better attested record concerning any bird than that of the arrival of the Bluebird, March 24, all along the forty-fifth parallel in Wisconsin and Minnesota. A great change now took place in their speed. They were two months and a day in passing from latitude 45° to latitude 47°. They did not appear at Frazee City, Minn. (lat. 46° 33’), until May 25; nor was the record accidental, since the same observation has been sev- eral times recorded in former years. May 29a pair of stragglers arrived at Portage la Prairie, Manitoba, the first Mr. Nash had ever seen in the province. They remained, and at last accounts were breeding. This is one of the most northern records for the species. Mr. Seton (now Thompson) states that it is rare in Manitoba, but most common in the region about Winnipeg. Again, as in the case of the Robin, the extreme western records are found to be much later than the eastern. At Ellis (lat. 38° 55’), just west of Manhattan, Kans. (where the species wintered abundantly), none were seen until March 19; and at Vermillion, Dak. (lat. 429 56/), they did not arrive until March 29. The bulk followed the first very closely, and in but one or two cases was its arrival more than three or four days later. In the fall of 1884 at Elk River, Minn., the departure of the bulk and the last of the Bluebirds was recorded October 10; and at Des Moines, Iowa, October 25. At Mount Carmel, Mo., the last was seen October 28. In the spring of 1885 a set of notes was received from about latitude 37°, which can be regarded as indicating either winter residence or very early spring migration. These refer to the presence of Bluebirds dur- ing the first week in February in Illinois, Missouri, and Kansas. A little farther north, at Odin, IIL, one was seen February 7. If these records indicate migration, it was at a standstill during the next three weeks, since no other evidence of movement was reported until the last two days of the month. , The bulk of males came to Saint Louis February 28, closely following 294 the first, which had been seen there February 27. February 28 they were seen also at Mount Carmel and Fayette, Mo. The next warm wave (March 3) brought them to Paris and Griggsville, Ill, and the next day they reached Ferry, Iowa, and Aledo, Ill. March 9 was a great day for the movement of Bluebirds in southeastern Iowa, where’ they were reported at Morning Sun, Richmond, and Coralville, though they had been seen the day before at Des Moines and Newton, in the center of the State. They were seen also March 9, at Peoria, Ill., but the real movement in this part of Illinois took place March 14, at which date they reached Tampico (both observers), Fernwood, and Chicago, and also Clinton, Wis. At this time the van rested at latitude 44° 30’, in Illinois and Iowa, remaining there during more than a week of freez- ing weather, until March 26, when, according to the testimony of the reports, they spread to Williamstown, Iowa; Stoughton, Milwaukee, Leeds Center, and New Cassel, Wis.; and Lake City and Excelsior, Minn. Hardly a note was made during the next five days, and then a strong movement was noted. Mareh 31 they reached Ripon, Wis., and Hastings, Minneapolis (two observers), and Saint Cloud, Mivn. Further advance in eastern Wisconsin was strangely delayed, and the three stations in the vicinity of Green Bay did not report a Bluebird until the last week in April. In the western part of the district migration was still slower. The first was reported from Linwood, Nebr., April 27; Huron, Dak., May 16, and Oak Point, Manitoba, May 26, thus showing the peculiarity already noted in the spring of 1884, namely, that the Bluebird, after traveling in company with Robins, Blackbirds, Killdeers, Ducks, and Geese from its winter home to latitude 44°, then drops be- hindhand and occupies a month longer than they in performing the rest of its journey. In the fall of 1885 the last Bluebird was reported from Elk River, Minn., October 16; from River Falls, Wis., October 13; Lanesboro, Minon., October 23; Milwaukee, Wis., October 10; Grinnell, Iowa, No- vember 4; Fernwood, Ill., October 10; Des Moines, Iowa, October 24: Iowa City, Iowa, October 24, and Mount Carmel, Mo., October 30 Three troops of Bluebirds were seen going south at Saint Louis, Mo., September 9, and a flock of over 300, October 7. 767. Sialia mexicana Swains. [23.] Western Bluebird. A straggler from the Rocky Mountain region. In Concho County, Tex., it is a rare winter visitor (Lloyd). At Boerne, Tex., Mr. Nathan Clifford Brown shot two specimens, each from a small flock, January 28 and March 1, 1883 (The Auk, Vol. I, 1884, p. 121). Stragglers have been recorded from Minnesota and Iowa. 768. Sialia arctica (Swains.). [24.] Rocky Mountain Bluebird. This species is seldom found in the Mississippi district except on the high plains of the West and Southwest. It breeds in the mountains, from latitude 36° northward far into British America, and winters from 295 Kansas southward. It was noted by only two of our observers. At Sav Angelo, Tex., an immense flock was-seen during the winter, and at Ellis, Kans., a few were seen during migration. Previously it was recorded as an abundant winter visitor at Boerne, Tex. (Brown). Most of the spring movement of this species occurs in the latter part of February and in March. It was found in Texas as far east as Gaines- ville, and has also occurred accidentally in Illinois opposite Dubuque, Iowa. It was also probably seen in the fall of 1883 at Caddo, Ind. Ter., but was not shot, hence the identification is not complete. In the fall of 1884, at San Angelo, Tex., the Rocky Mountain Bluebird first appeared October 8. Mr. Peters writes that at Bonham, Tex., he saw these birds for three or four winters in succession, the last time being in 1880. INDEX. Acadian Flycatcher, 36, 153-154. Acadian Ow}, 121.
