SIB: I have the honor to transmit herewith, for approval and for publication, Part First of a treatise entitled " Birds of the Colorado Yalley w, which I have taken great pains to render worthy of favorable consideration as a repository of scientific and popular information concerning North American ornithology. I am, Sir, &c., DR. F. Y. HAYDEN, U. 8. Geologist, &c., &c., Washington, D. C. iii 256248 PEEFATOEY NOTE U. S. GEOLOGICAL AND GEOGRAPHICAL SURVEY OF THE TERRITORIES, Washington, D. 0., November 1, 1878. RESULTS of Dr. Coues's continued studies of North Ameri- can ornithology, in connection with the Survey under my charge, are herewith presented as one of the series of Miscel- laneous Publications (No. 11). Should circumstances favor the completion of the work, upon which the author is still engaged and which is already not far from finished, the remaining portion may be expected. The present treatise may be regarded as com- plementary to the "Birds of the Northwest" (Misc. Pub. No. 3). It covers much ground not gone over in the latter work, in all that relates to the technicalities of the general subject, as well as to the particular life-histories of the birds composing the remarkable avian fauna of the Colorado Basin. As originally projected for publication in a different connection, the work consisted merely of a report upon the peculiar features of bird- life in the area under consideration, with biographies of the species not treated in the "Birds of the Northwest". But the author's resources have proved to be so largely in excess of the requirements of such a report that the work has outgrown the limits of a single volume, and become a full exposition of our present knowledge of the subject, by the incorporation of much technical matter concerning North American ornithology at large, hitherto the private possession of the author and now first made accessible to the public. The whole subject of the bibliography of North American ornithology, and of the synonymy of North American birds, has been worked up anew from the very bottom, as a matter of original personal investigation admitting of nothing at second- hand. Not only the birds of the Colorado Valley, but also all others of North America, are thus exhaustively treated, their synonymy and bibliography being at length placed upon a satisfactory basis. In points of accuracy, completeness and thorough reliability it is believed that this side of the work VI BIEDS OF THE COLORADO VALLEY will compare so favorably with what has before been done in the bibliography of any department of science as to furnish a model for the future. Since the appearance of the "Birds of the Northwest " it has been a matter of frequently expressed regret that the accounts of the birds treated hi that volume did not include such descrip- tions of the species as should enable those using the work to identify specimens they might have in hand. It has been deemed advisable to supply this want in the present treatise, especially as a considerable proportion of the characteristic birds of the Colorado Yalley are not so well known as are most of those inhabiting the region of the Missouri. The descrip- tions are original, in nearly every case having been drawn up by the author directly from the specimens themselves, with great regard to precision of concise statement. All the species ascertained to occur in the Yalley of the Colorado, being those which form the special subject of the work, are thus treated, the other North American birds of which the volume takes account being introduced only with their synonymy and a brief state- ment of the habitat of each. Eespecting the biographies or " life-histories ?? of the birds, which constitute the main text of the present volume, the author's view, that this portion of the subject should be so far divested of technicality as to meet the tastes and wants of the public rather than the scientific requirements of the schoolmen in ornithology, will doubtless meet with general and emphatic approval. It is possible to make natural history entertaining and attractive as well as instructive, with no loss in scientific precision, but with great gain in stimulating, strengthening and confirming the wholesome influence which the study of the natural sciences may exert upon the higher grades of mental culture; nor is it a matter of little moment to so shape the knowledge which results from the naturalist's labors that its increase may be susceptible of the widest possible diffusion. The first twelve sheets of this volume (to p. 192) were printed in 1876, when other engagements obliged the author to inter- rupt the preparation of the work. The printing was resumed in 1878, and is completed at the date of this prefatory. A few impressions of the earlier sheets may have already been in pri- vate circulation, but no portion of the work is published prior to this date. The types of pp. 1-192 having been distributed without stereotyping after only 1,500 impressions had been PREFATORY NOTE Vll taken, it will be necessary to reset this portion if a larger edi- tion is required; and in order to secure uniformity, the composi- tion should be, if possible, infac simile. The illustrations of the present volume are chiefly those which formerly appeared in the same author's "Key to North Ameri- can Birds ". According to the report rendered by the author, the present part of the work carries the subject through Passeres to Laniidce. The whole consists in a systematic treatise on the families, gen- era and species represented in the Colorado Valley — that is to say, in the whole region drained by the Colorado Eiver of the West and its tributaries, as far south as the present Mexican boundary of the United States. The watershed of this great river includes Arizona, much of New Mexico, Utah, and Nevada, a part of the State of Colorado, and some of Southern California. The faunal area thus circumscribed is nearly that of the " Great Basin", and corresponds with the "Middle Faunal Province" of some zoo-geographers, as distinguished from the "Western" and t l Eastern " Provinces respectively. The main chain of the Eocky Mountains, or great continental divide, bounds it on the east, as the Sierras Nevadas do on the west. To the north lies the Salt Lake Valley; southward the boundary is an arbitrary political one. In the last-named direction, the fauna changes insensibly by the gradual gain of a "neotropical" complexion, though many " nearctic" features are impressed upon the table-lands of Mexico. The proper fauna of that country is prefigured in the area under consideration by the various subtropical forms of bird- life which have successively been found within the border of the United States in the Valley of the Gila, as in that of the Lower Eio Grande of Texas. Both to the east and to the west the geographical boundaries already mentioned correspond quite closely with the limits of the natural faunal areas ; for we miss in the Colorado Valley some characteristic forms both of the Pacific slope proper and of the Eastern United States at large. Northward the Great Basin narrows like a wedge thrust in between the converging Eastern and Western Provinces. No other portion of the United States of equal area offers such varied surface conditions and such climatic extremes. The region is hedged about by mountain ranges of immense extent and elevation, and contains many other lofty chains and peaks, while the greater part of the country is low, hot and arid. The viii BIRDS OF THE COLORADO VALLEY highly diverse topography of the country is strongly reflected in the temperature, the rainfall, and the course of the seasons of this remarkable region, and these in turn leave their impress upon animal and vegetable life, with the result that contiguous areas of insignificant geographical extent may differ as much in their natural productions as if they stretched over many degrees of latitude. In the Colorado Basin, in fact, as appears to be the case in most portions of Mexico, the distribution and migrations of birds may be regarded as affected by altitude rather than by latitude or longitude 5 and we have a striking instance of the convertibility of these two factors of the general equation. The birds here find their summer and winter homes, and perform their migrations, rather according to " the lay of the land" than with reference to degrees of latitude. A portion of the Colorado Valley, in Southwestern Arizona and adjoining parts of California, has long been known as the hottest place in the United States. At Fort Yuma, on the Colorado Eiver at the mouth of the Gila, in latitude 32° 32', longitude 114° 36' 9", the mean annual rainfall does not exceed five inches. A temperature of 119° F. has been recorded, and for weeks in succession the mercury may rise above 100° daily. For several hundred miles the great river rises but little, its elevation at Fort Mojave, for instance, being only about 525 feet. South- ern and Western Arizona is a torrid, alkaline waste ; in fact, a part of the "Great American Desert"; yet in the central portion of the Territory rise the magnificent San Francisco Mountains, 12,562 feet high, pine-clad, and snow-capped during a portion of the year ; and at Fort Whipple, with an altitude of 5,335 feet, the general course of the seasons is not materially different from that in the Middle Atlantic States. A day's jour- ney from the last-mentioned locality will show differences in the bird-fauna comparable, for instance, to those distinguish- ing Massachusetts from the District of Columbia. Many of the birds of Fort Yuma and Fort Whipple respectively are total strangers to each other. Such striking features as are here briefly indicated render the study of the birds of this region specially attractive, and exact information respecting their distribution and movements within the area in question is very desirable. The whole subject is elucidated in detail in the present treatise. Aside from the local perturbations resulting from topograph- ical and climatic diversity within small areas, the bird-fauna of the Colorado Yalley is in a sense homogeneous and rather PREFATORY NOTE IX compact, being well marked by a large proportion of highly characteristic, if not wholly peculiar, species. The resulting aspect of the bird-fauna is far more strongly pronounced than is ordinarily found to be the case with areas of corresponding dimensions. As might be expected from aridity of such extent and to such degree as is witnessed in the Colorado Valley, the prime mark of the birds of the region is that pallor of colora- tion which is now well known to result from the combined effects of heat and dryness. It is the extreme of a condition very sen- sibly offered by the birds of the Great Plains at large. In some cases we here find that the modification of a common stock has produced forms sufficiently distinct from their respective allies to meet the requirements of " species "j while in many more instances strongly marked geographical races are developed by the same natural causes operating less intensely, less continu- ously, or upon less susceptible material. It is unnecessary in this place to cite examples, as such cases are already well known to ornithologists. It may be added, as a curious fact in the matter of the modifications here witnessed, that the tail is length- ened in many cases of birds which otherwise differ from their respective allies mainly by the bleached coloration just noticed. A few words upon the progress of our knowledge of the birds of the region under consideration will not be out of place here. It is only within the last twenty-five years that we have acquired any considerable information respecting the ornithology of the Colorado Basin. Shortly after Nuttall and Townsend largely increased our knowledge of Western birds from localities much further north, Dr. William Gambel gave us welcome advices in various papers published by the Philadelphia Academy from 1843 to 1849 $ and this naturalist may be considered as a pioneer in this field. He was succeeded by Dr. S. W. Woodhouse, who accompanied an expedition to the Zufii and Colorado Eivers, and prepared a valuable paper published in 1853 in Sitgreaves's Report. Mr. Gassings well-known "Illustrations", completed in 1856, contain colored figures of many interesting species, and include the timely field-notes of Col. G. A. McCall, Dr. A. L. Heermann, and other naturalists who had made personal observations in the field. A stride forward was taken when the Reports of the Pacific Eailroad and Mexican Boundary appeared ; the technicalities of the subject being admirably worked out by Professor Baird in these volumes, while the same publications include the field-notes of the naturalists attached to the several X BIRDS OF THE COLORADO VALLEY Surveys, as Dr. Heermann, already mentioned. Dr. 0. B. E. Ken- nerly, Mr. J. H. Clarke, Mr. Arthur Schott, and others. Dr. T. C. Henry, then of the Army, published several valuable papers on the birds of New Mexico at about this time, and Dr. J. G. Cooper gained much additional information during his some- what later residence in Arizona. Much, however, remained to be done when Dr. Coues entered Arizona in 1864, and spent nearly two years in studying the natural history of the Terri- tory. He published in 1866 the first formal list of the birds of Arizona, describing new species and adding others to the fauna of the United States ; and his personal experiences, now for the first time set forth in full, afford a large basis of the biographi- cal portion of the present treatise. Lieutenant (now Captain) Charles Bendire, U. S. A., subsequently resided for some time in Southern Arizona, where he made large collections of nests and eggs, and furnished much information respecting the breed- ing habits of the birds, which was published in part by Dr. Coues, but principally by Dr. T. M. Brewer. By far the most important contributions hitherto offered to the natural his- tory proper of the birds of New Mexico and Arizona are those recently made by Mr. H. W. Henshaw, during his connection with the Engineer Survey West of the 100th Meridian. This accomplished ornithologist has added many new species to the fauna of the United States, and has published the most complete list we possess of the birds of Arizona ; while his extensive memoir in the 4to Eeports of the Survey mentioned gives us much new information respecting the distribution and the habits of the birds of New Mexico and Arizona. I may also advert in the present connection to several late publications upon the birds of contiguous regions as bearing upon the special subject. Among these may be mentioned the papers on Texan birds by H. E. Dresser, H. B. Butcher, 0. A. H. McCauley, J. C. Merrill, and Gr. B. Sennett ; on those of Colo- rado by C. E. Aiken and C. H. Holden, and E. Eidgway ; to Mr. Henshaw's List of the Birds of Utah ; to Dr. Cooper's work on the ornithology of California ; to Mr. J. A. Allen's Eeconnois- sance in Kansas, Colorado, Wyoming, and Utah ; and especially to Mr. Eidgway's important memoir on the Ornithology of the Survey of the 40th Parallel. It is believed that the present volume will be found to be a thorough digest of the information we possess upon the subject. F. Y. HAYDEN, United States Geologist.

TURDID.E fin HE birds of this family, together with those of the families JL which follow in this work to the Flycatchers (Tyrannidce), inclusively, belong to the great group of Passer 'es. Any Passerine bird of this country may be recognized by the character of the feet, .which are perfectly fitted for grasping — in other words, for perching upon such support as the twigs of trees, for instance. Though many kinds of birds, such as Birds of Prey, Herons, and various others that might be mentioned, perch habitually, yet the truly insessorial foot, as exhibited among Passeres, is * unmistakable in several features. The hind toe, which is never wanting, is inserted on the same level as the front toes collec- tively; it is always directed straight backward, being thus op- posed directly to the front toes ; it is of considerable length, and its perfect mobility is secured by the separation of its prin- cipal muscle from that one which bends the other toes collec- tively. The claw of the hind toe is at least as long as that of the middle anterior toe, and often longer. Neither of the front toes is ever reversed in position, to effect such arrangement of the digits in pairs as is witnessed in some Picarian birds, as Woodpeckers, Cuckoos, &c.; nor are the toes ever soldered together for a long distance, as in the Kingfishers ; nor are their joints abnormal in number, as in some of the Swifts ; nor are the feet webbed or lobed, as in many wading and all swimming birds. In addition to these char- acters, it may be stated that the legs are clothed with feathers down to the tibio-tar- sal joint; and that the tarsus and toes are Fm ]...TypicalpM8erine invested with hard, horny integument, likeFoot- that encasing the bill. Such a foot as results from these con- 1 B c 2 CHARACTERS OF PASSERES ditions is rarely found outside the group Passeres ; and any non-Passerine bird, the foot of which conforms with the fore- going description, may be recognized by some collateral fea- tures. The foot of a Hawk or Owl, for instance, is strictly insessorial in character, and, in fact, possesses very great grasping powers ; but the bill of these birds is furnished with a soft cere, which no Passerine bird exhibits. In a Pigeon, with decidedly insessorial feet, the covering of the feet, like that of the bill in part, is soft and skinny, not perfectly horny. A Hummingbird, the foot of which is perfectly iusessorial, is ascertained to be non-Passerine by the fact that it has but six wing-quills of the secondary series — all Passeres having more than six. And, in general, closely as some of the Picarian birds of this country may resemble the Passeres, some peculiar- ity of the feet will suffice for their recognition. Thus, in the Parrots, Cuckoos, and Woodpeckers, the toes are in pairs, two before and two behind ; in the Kingfishers, the toes are exten- sively soldered together, the covering of the tarsus is rather soft, and, moreover, the tibia is naked below; in the Swifts and Goatsuckers, either the hind toe is elevated above the plane of the rest, or it is turned sideways, or there is a web at the bases of the front toes, or these last have an unusual number of joints, or several of these features occur in cotnbi nation. Humming- birds, the only remaining North American Ficaritt, have, as already said, a nearly Passerine foot ; but, in this case, the above-mentioned feature of the secondaries is distinctive. There is also a peculiarity of the wing of Passeres that serves to distinguish birds of this group from those of probably any one of the others, excepting Picarim, and even from the ma- jority of Picariai. In a Passerine bird, the row of " greater " wing-coverts — those that overlie the secondary quills — are not more than half as long as these quills; while in most non- Passerine birds — perhaps in all birds below Picarice — the re- verse is the case. The details of structure of the tarsal envelope of Passeres may be noticed in passing. In the majority of the birds of this group, the tarsus is covered on each side with a horny plate, nearly or quite undivided, meeting its fellow in a sharp ridge behind ; and, in some cases, this general fusion of the envelope proceeds so far that the front of the tarsus likewise presents a nearly or quite undivided surface, the whole tarsus being then encased in a " boot," as it is called. The more complete con- CHARACTERS OF PASSERES 3 ditions of fusion of the envelope — those showing the entire lat- eral plates, sharp-ridged behind, whether or not the front of the tarsus be also fused — are commonly associated with certain anatomical characters which affect the vocal powers of the birds; there being a complex arrangement of the muscles of the lower larynx. Most of the North American Passeres exhibit these features combined, and constitute a minor group Oscbies, which is denominated a suborder by those who hold Passeres as an order. The famil}r of the Larks (Alaudidce) is the only exception among our birds ; for here the larynx is a highly- developed vocal organ, while the tarsus shows a different struc- ture of the envelope, being covered on the outer side with two series of scales lapping around before and behind, and having the hinder edge blunt. This state of the tarsus prepares us for the further modification witnessed in a single one of the North American families of Passeres, namely, the Tyrannidce, or Fly- catchers, in which the tarsus is blunt behind, being covered with a set of variously-arranged plates lapping entirely around. Such condition, in connection with an incomplete development of the vocal organ, marks off the Tyrannidw as representatives of a second minor group of Passeres, called Clamatores, in con- trast with Oscines. The purpose of these opening paragraphs will have been at- tained, if enough has been said to enable the reader to gain an idea of the limits, and of certain leading features, of the great group Passeres, which includes the majority of all known birds, and something like two-fifths of those of North America. Tlio families of Passeres which occur in the Coloradan region are the Turd idee, SaxicoUdce, Cinclidce, Sylviidce, Cliamceidce, Par idee, Sittidce, Certhiidm, Troglodytidce, Alaudidce, Motacillidce, Sylvicolidce, Tanagridce, Hirundinidce, Ampelidce, Vireonidce, Lani- idcv, Fringillidce, Icteridce, and Corvidce, all of which are Oscine, and the Tyrannidce, which is Glamatorial. These will be sever- ally considered in the sequence here indicated. With these few preliminary considerations touching the Pas- seres at large, we will at once take up the subject of the present chapter, namely, the 4 CHARACTERS OF TURDID^ Turdida\ or Thrushes. CHARS.* — Oscine Passeres, in which the characters of this great group are highly developed. Lateral tarsal plates lami- nar, meeting in a sharp ridge posteriorly; anterior scutella often fused in a 'continuous lamina. Toes deeply cleft — the outer anterior one to the distal end of its basal joint, the inner anterior almost to its very base. Bill more or less subulate, as usual in insectivorous birds, usually notched near the end, the commissure not angulated, nor very deeply cleft. Nostrils oval, nearly or quite reached but not covered by feathers. Kic- tus with well-developed bristles. Primaries ten, the first of which is spurious, or short ; second* shorter than the fourth. Tail-feathers twelve, not stiffened nor acute. The Turdidce are very closely related both to the Saxicolidce and Cinclidce among American forms, as well as to certain exotic groups — perhaps too closely to justify their separation when all their interrelationships are taken into consideration. Viewing, however, the North American forms alone, very fair diagnostic points may be determined, as will be seen on com- paring the characters given in Chapters II. and III. The vocal apparatus of the Thrushes is highly developed, and some of the members of this family, like the Wood Thrush and Mockingbird, are among the most famous of songsters. Thrushes are distributed throughout all of temperate North America, as well as most other portions of the globe. Our species are mainly birds of the woodland, though a few kinds enliven with their song the arid and treeless wastes of the Southwestern Territories. A majority of the North American species are represented within the limits of the Coloradan Basin ; they may readily be grouped in three subfamilies, the eading antithetical characters of which are as follows : — TURDIN^E. — Tarsi booted. Bill short, scarcely or not de- pressed, moderately cleft. Legs stout. Tail-feathers widen- ing a little toward the end, the tail thus becoming squarish or fan-shaped. MYIADESTIN^E.— Tarsi booted. Bill very short, much de- pressed, widened at base, deeply cleft. Legs weak. Tail-feath- ers tapering, the tail being thus rendered somewhat cuueate. *The characters of this and of other groups are drawn up with reference to the forms treated in the present work, and may or may not require modifi- cation in order to their equal applicability to extra-limital representatives. CHARACTERS OF TURBINE 5 MIMIN^E. — Tarsi scutellate anteriorly (scales seven in num- ber). Bill variable; sometimes as in Turdince, sometimes as long as the head and bent like a bow. Legs stout. Wings usually shorter than the tail, which is more or less graduated, with broad, rounded feathers. Other characters will be adduced under the heads of the respective subfamilies. SUBFAMILY TURDIN^E: TYPICAL THRUSHES CHARS. — With the tarsus, in the adult, u booted" or envel* oped in a continuous plate, formed by fusion of all the tarsal scutella excepting two or three just above the base of the toes. (This is a strong character; for the * few other birds of this country which \ show the same feature are quite dif- erent in other respects.) Wings more or less pointed, longer than the tail; . first primary spurious, or very short ; second longer than the sixth. Bill moderate, shorter than the head, straight, more or less subulate, little depressed at base, with moderate bristly rictus. Nostrils oval, nearly or quite reached by the frontal feath- ers. Tail-feathers widening somewhat - ; toward their ends: the tail as a whole Fro. 2.—" Booted " tarsus. (Foot somewhat fan-shaped, not decidedly of Robin, natural size. N. B.— The lettering of the cut indicates propor- forked at the end, nor much gradu- ti°nal lengths of tarsus and middle toe with claw, and the numeration of a ted. the several digits of a bird's foot.) This group is nearly cosmopolitan, and reaches a high state of development in the warmer parts of America, where it is represented by various genera and numerous species. There are in all upward of one hundred and fifty accredited species of Turdincv, most of which are referable to the genus Turdus and its subdivisions. The United States species are few in number, and all of them belong to the single genus Turdus ; though species of Caiharus, an allied form, may possibly be yet found on our southern border. * The Thrushes are generally distributed over North America, in wooded regions, but will not be found, except casually, in those localities which are devoid of trees or bushes, even 6 GENERAL ECONOMY OF THE THRUSHES though such places are within the general area of distribution of the respective species. They are insectivorous, like most birds, in fact; but, like very many others that feed mainly upon insects, they also eat berries and various other soft fruits. The Eobin, for instance, is extravagantly fond of the berries of the common Poke (Phytolacca decandra) ; and, during the season when this fruit is ripe, specimens are often found with not only the plumage, bill, and feet, but also various interior parts of the body, dyed with the purple juice. The Thrushes are migra- $ory in the United States. They are not properly to be con- sidered gregarious, though some of them, like the Eobin, go together in troops of hundreds at certain seasons. They are arboreal in general habit; yet much of the time is spent on the ground in the search for worms and insects. To illustrate the case, again, in the instance of the familiar Kobin, every one will recall the sprightly excursions of this bird on the green- sward of our parks and gardens during the breeding-season, and remember how swiftly it runs, with lowered head ; how it then draws itself up at full length, displaying its trim and shapely form to best advantage ; how then, satisfied that no danger is to be apprehended, it tugs at the grub that lurks in the roots of the grass, and finally bears it away to the nest, on a bough of the nearest apple-tree. The mode of nesting varies according to the species ; most of the Thrushes build upon trees or bushes, but some, less ambitious, are content to nestle on the ground. The order of their architecture is never elabo- rate or ornate ; the nests, in fact, are rather rude, bulky, and inartistic structures, more notable for strength and stability than for beauty of finish ; they are built of leaves, grasses, rootlets, and similar materials, often strengthened with mud. The eggs are usually four, five, or six in number, blue or green in color, with or without reddish spots ; some of the most closely- allied species lay eggs distinguishable with as much certainty as the birds themselves. Under favorable circumstances, two, or even three, broods of young may be reared in one season. The great voracity of young insectivorous birds is perhaps in no case more strongly illustrated than in this group. If the Robins were to feed all other seasons exclusively upon the fruits of the orchard and garden, we should still remain in their debt for the numberless thousands of noxious insects they destroy during the period when they are rearing their young. The de- stiuction of such useful birds cannot be too severely reprobated, CHARACTERS OF THE GENUS TURDUS 7 even upon selfish grounds, to say nothing of the higher and more generous motives which should suffice for their protec- tion. For we are not alone indebted to the Thrushes as friends favoring our economical projects. They lay strong claim to our regard as musicians. It is true that the song of the Eobin is a humble effort, remarkable for nothing so much as for its heartiness, simplicity, and persistence; yet some of the Thrushes, like the Hermit and the Wood Thrush, sing with wonderful power and effect. Genus TURDUS Linn. THE characters of the single genus represented in North America being in effect the same as those of the sub- family already given, need not be recapitulated. The several species to be treated fall in three groups, or subgenera, wjiich may be thus analyzed: — Planesticus. — Sexes similar. Bill notched near the end, little widened at base. Tarsi little longer than the middle toe and claw. Beneath mostly unicolor, with streaked throat. Large ; stout. Hesperocichla. — Sexes dissimilar. Bill unnotched. Male with a black pectoral collar. Otherwise like Planesticus. Hylocichla. — Sexes similar. Bill notched near the end, much widened and depressed at base. Tarsi decidedly longer than the middle toe and claw. Beneath spotted. Of small stature, and rather slender form. It may be remarked that the first plumage of young birds is spotted, in this genus ; and that the tarsal scutella are only fused completely in adult life.* All of the North American species of this genus occur in the Coloradan region excepting one, the Wood Thrush, T. mnste- Unus. While there will be no difficulty in recognizing the species of Planesticus and of Hesperociclila, the smaller species of Hylocichla require careful discrimination, nor are ornitholo- gists agreed upon the more correct view to be taken of their interrelationships. Four species are distinct, beyond question : T. mmtelinus, T. fuscescenSj T. swainsoni, and T. pallasi ; but *This latter subject is well illustrated by Dr. J. J. Kaup, in an article en- titled " Ueber die Bedeckung der Fusswurzel des Turdus migratorius ", in : Arch, fiir Naturg., sechszehuter Jalirg. Bd. I. ss. 42, 43, hierzu Taf. ii, Fig. 1-5. 8 SYNONYMY OF TURDUS MIGRATORIUS some other forms which have been admitted to be specific are not so well established. It may be further observed that several of the names now currently adopted may have to give way, in the end, if the species described by some of the older authors, as Pennant, Latham, Gmelin, and Pallas, can be fully identified.

Bill much clouded with dusky. $ $ in winter and young: Similar to the adult female, but receding some- what farther from the $ in summer by the duller colors, the paleness and restriction of the chestnut, with its extensive skirting with white, lack of distinction of the color of the head from that of the back, tendency of the white spot before the eye to run into a superciliary streak, and dark color of most of the bill. Very young birds have the back speckled, each feather being whitish centrally, with a dusky tip, and the cinnamon of the under parts is spotted with blackish. The greater coverts are tipped with white or rufous, fre- quently persistent, as are also some similar markings on the lesser coverts. Albinos, partial or complete, of this species are of comparatively frequent occurrence. In specimens bred in the Colorado Basin and other portions of the South- west, there is a tendency to greater length of the tail ; this member averag- ing in length nearly at the maximum of that of Eastern specimens. With this is coupled the reduction or extinction of the white spot on the exterior tail-feathers. FIG. 3.— Head of Robin, natural size. THE Eobin is found in all parts of North America. It also occurs in Greenland, on islands in Bering's Sea, on several of the West India islands, as Bermuda, Cuba, and Tobago ; and through Mexico to Guatemala. It has even been known to cross the Atlantic, having been several times shot in Europe.* Such general statement of its distribution requires little if any qualification. For, though it is a woodland bird, like all of its tribe, and therefore scarcely to be found in certain portions of the country, where desert or prairie fail to afford requisite con- * In the above synonymy, numerous European references are given, which must not be presumed, however, to indicate as many different instances of its occurrence, since several may relate to the same case. Dr. Cabanis sup- poses the individual taken in Germany in December, 1851, to have leached that country via Siberia, not by crossing the Atlantic. DISTRIBUTION AND HABITS OF THE ROBIN 11 ditions; nevertheless, in the course of its extensive migrations, ifc may at least pass over such tracts. Thus I have observed large flocks in the open and sterile portions of Dakota and Montana — flocks that were journeying across the country, and had stopped for rest and food in the fringe of trees along the lesser water-courses. It is not easy to determine the center of abundance of so widely diffused a bird as the Eobin. Excluding the extremes of its range, reached by comparatively few individuals, such as Greenland, the West Indies, or Central America, its num- bers appear to be determined solely by the food-supply. Since settlement of the country and cultivation of the soil result in an increase of its favorite articles of diet, it is nowhere more numerous than in populous districts. In the Southwest, it appears to be becoming more abundant than it formerly was, doubtless in direct consequence of the progress of civilization. All the recent observers who have recorded their experience agree in their representations to this effect. In any given locality, short of the extremes of its range, the bird appears to be more abundant during the migration — especially the autum- nal movement — than at other seasons. This may be due to two causes. In the first place, there is an actual increase in number by new arrivals ; and, secondly, the birds collect together in large companies, and become in consequence more conspicuous than they are when generally dispersed. In some regions, where trees are few and far between, as in an instance already cited, Eobins will rarely be se6n except in the spring and fall. In intermediate portions of the United States, they seem to be most numerous early in the spring, and in the latter part of autumn, when straggling flocks of hundreds roam through favorite tracts of woodland and shrubbery, or betake them- selves to the neighboring fields. The Robin is strictly a migratory bird, like most insectivor- ous species which inhabit the northern hemisphere. There is a general north and south movement of the species as a whole, during the changing seasons of the year — a movement directly related to the sources of food-supply. Nor should it be in- ferred from the fact that Eobius may be seen in a given locality during the whole year, that the tide of migration has not passed ; for it may be that the individuals present at one season are not the same as those that remained during a pre- vious period of the year. The fact appears to be, that, as a 12 HABITS OF THE ROBIN rule, at least, there is a replacing of one set of individuals by another ; so that, though the bird as a species may be resident, the birds individually have obeyed the migratory impulse. Wide as the Eobin's distribution is, the limits of its summer and winter residences are comparatively little narrower. Its breed- ing-range extends from Arctic America to the Alpine regions of Mexico j its winter home, from the Northern States to Cen- tral America. It is a hardy bird, capable of enduring cold to the freezing-point of mercury. Thus, it will be seen, the bird is "resident "in one sense throughout the greater portion of its range. Nevertheless, the general migration favors its pres- ence in greatest numbers in the Southern States during winter, and in the Northern during the summer. The Eobin is a great eater of berries and soft fruits of every description 5 and these furnish, during the colder portions of the year, its chief sustenance. Some of the cultivated fruits of the orchard and garden are specially attractive ; and no doubt the birds demand their tithe. But the damage done in this way is trifling at most, and wholly inconsiderable in compari- son with the great benefit resulting from the destruction of noxious insects by this bird. The prejudice which some per- sons entertain against the Eobin is unreasonable; the whole- sale slaughter of the birds which annually takes place in many localities is as senseless as it is cruel. Few persons have any adequate idea of the enormous — the literally incalculable — numbers of insects that Eobins eat every year. It has been found, by careful and accurate observations, that a young Eobin, in the nest, requires a daily supply of animal food equiv- alent to considerably more than its own weight! When we remember that some millions of pairs of Eobins raise five or six young ones, once, twice, or even three times a year, it will be seen that the resulting destruction of insects is, as I have said, simply incalculable. I have no doubt that the services of these birds, during the time they are engaged in rearing their young alone, would entitle them to protection, were the parents themselves to feed exclusively upon garden-fruits for the whole period. But at this time the diet of the old birds is very largely of an animal nature ; nor is this the only season during which the destruction of insects goes on. Upon the first arrival of the main body of the birds early in the spring, long before any fruits are ripe, they throw themselves into newly-plowed fields, and scatter over meadows, lawns, and parks, in eager HABITS OF THE ROBIN 13 search for the worms and grubs that, later in the season, would prove invincible to the agriculturist, were not their ravages thus stayed in advance by the friendly army of Eobins. It is a matter of congratulation that the good services of the Eobin are becoming duly appreciated — thanks to the timely and judicious interference in its behalf on the part of many of its friends; among whom no one, perhaps, deserves higher praise for his active and successful exertions than Dr. Thomas M. Brewer, of Boston. The bird is now very generally pro- tected by legislative enactments, during a portion of the year at least ; it is to be hoped that the laws may be made still more stringent, and the " close" time become co-extensive with the year itself. As an object of a sport," the Eobin can possess no attractions save to idle children of larger or smaller growth ; while its commercial value, as an article of food, is wholly in- considerable. There are, therefore, weighty and cogent reasons why the Eobin should be protected by law at all seasons ; for there would rarely if ever be difficulty in gaining permission, upon proper representation, to destroy the very few that might be required for scientific purposes, or to please the capricious palate of an invalid. There is little need to pursue the history of the Eobin to the details of the bird's daily life ; upon such points the children are competent ornithologists; and those of us who may have forgotten our early experiences need only look out of the window at the right time. A word of record respecting the nest, may, however, not be out of place. This is one of the most conspicuous pieces of bird- architecture about the home- stead— the Kingbird's, the Oriole's, and the various Swallows7 nests idone approaching it in this respect. The horizontal bough of an orchard tree, not far from the ground, is a favor- ite situation ; though the Eobin is not very particular, and will sometimes build, like the Pewit Flycatcher, in odd and unsuspected nooks about an out-building. The nest is too bulky for concealment, and no art is attempted. A mass of the most miscellaneous material, chiefly of vegetable nature, such as leaves, weed-stems, moss, grasses, and rootlets, but sometimes including hair or woolr surrounds a rather neat cup of mud, which in turn is lined with finer vegetable fiber. The shape of the nest varies, of course, with the character of the support upon which it rests ; in size it is about five inches wide, or deep, with a cavity half as4arge, the walls and flooring being 14 SYNONYMY OF TURDUS very thick and substantial. Such nests do not readily yield to the weather. The eggs, numbering five on an average, perhaps, measure from an inch and one-eighth to an inch and one-fourth in length by three-fourths to four-fifths in breadth. When fresh, they are of a uniform, rich, greenish-blue color, without spots ; after being blown for some time, especially if exposed to the light, they fade considerably, becoming of a lighter green- ish, with less blue shade.

Young: For a short time after leaving the nest, the young are speckled or streaked above with pale yellowish or whitish ; usually especially noticea- ble as triangular spots on the wing-coverts. But these speedily disappear, when a plumage scarcely different from that of the adult is assumed. The present is the most strongly marked species of the subgenus Hylo- ciclila. In T. pallasi, the only^ther one showing both tawny and olive on the upper parts, the position of the two colors is reversed, the tawny occupying the rump, the olive the head. In no other species are the spots below so large, sharp, numerous, and generally dispersed, only the central line of the throat, middle of the belly, and the crissum remaining immacu- late. The purity of the white, moreover, only gives way to a faint, some- times almost inappreciable, tinge of buff on the breast. 30 DISTRIBUTION OF THE DWARF THRUSH variety ; yet it does not necessarily follow that the true Hermit Thrush is never found so far south. I should not leave this subject of the southerly distribution of the Audubon Thrush without calling attention to the fact that it constitutes one of the few exceptions to the general rule that southern repre- sentatives of a species are smaller than the others ; its larger size being unaccountable on any premises we at present command. The distribution of the Dwarf Hermit in latitude agrees with that of its eastern relative. This bird is the prevailing, if not the exclusive, form in the Pacific region, from Alaska as far north at least as Sitka and the island of Kodiak, to the ex- tremity of the peninsula of Lower California. Though it is par- ticularly attached to the immediate Pacific slopes, it yet spreads eastward to the Rocky Mountains. Dr. J. G. Cooper found it in the Colorado Valley, probably at Fort Mojave, where he was stationed for some time as a medical officer of the Army. I occasionally saw it in the mountains of Central Arizona, and within a year or two Mr. H. W. Henshaw has observed it still further eastward, in Southern Arizona, and among the headwaters of the Gila in New Mexico. These advices clearly show that the limit of eastward dispersion assigned by Mr. Ridgway (the valley of the Humboldt Eiver in Nevada), must be considerably enlarged. As to the movements of the species within the general area it inhabits, the accounts which have reached us are perplexing ; yet they may, I think, be adjusted, if we exercise due care. It is evident from Dr. Cooper's researches, that the Dwarf Hermit winters in lower portions of Arizona, a fact which both Mr. Henshaw?s observa- tions and my own would confirm, were this necessary ; and its occurrence at Cape St. Lucas shows probably the southernmost point reached at this season. Starting from these and corre- sponding latitudes, the bird migrates to Alaska, as already inti- mated, and breeds at the northernmost points it reaches. The limit of the breeding-range in the other direction remains to be determined, for it is pretty certain that Dr. Cooper, in speak- ing of nests which he found at Santa Cruz, and supposed to belong to the Dwarf Thrush, was mistaken. He describes the nests as placed " about five feet above the ground ", and says that they contained speckled eggs, neither of which statements agrees with what we know of the nidification and color of the eggs of the Hermit Thrush. Dr. Brewer has alluded to these discrepancies, which his great familiarity with the subject ena- DISTRIBUTION OF THE HERMIT THRUSH 31 bled him to perceive at once, though, somewhat inconsistently, he goes on to quote Dr. Cooper's account in connection with the Dwarf Thrush. We may without hesitation reject the whole record as far as it bears upon an alleged breeding of the Dwarf Thrush so far south, since there is no doubt that Dr. Cooper's nests were really those of the Olive-backed Thrush, or its variety ustulatus. Observations are wanting to determine the case precisely, yet, remembering how strongly elevation of surface affects the breeding-range of species, and that the Dwarf Thrush is found in wooded mountainous tracts, we may grant that it will probably be found to nestle much farther south than its Eastern relative is known to do. I should not be surprised if its dispersion during the breeding-season were found very closely correspondent with that of the Varied Thrush. Turning now to the better-known Hermit Thrush of the East, that shy recluse whose lowly home has been often entered by the curious naturalist, eager to learn its secrets, the first thing that strikes us as bearing upon its furtive movements is the lack of any trace of its presence in those subtropical regions to which the Wood Thrush and the Olive-backed and others re- sort in winter. We are not even sure that it takes the short flight from Florida, a favorite home, to any of the West India Islands. Though Dr. Gundlach, the veteran ornithologist of Cuba, whose labors for many years have done so much to eluci- date the birdrlife of that island, once recorded its presence there, it seems that he had really another species in view. Like the Catbird and the Thrasher, the Hermit Thrush finds in the groves and swamps of the Southern States a winter home so congenial that it need seek no further. Audubon in- formed us many years ago of its abundance in Mississippi and Louisiana; and later records, multiplying rapidly with the growing number of those who are interested in the delightful study of birds, not only confirm the statement, but extend its applicability to most of the Southern States. I well remember the admiration which this brave and hardy little bird used to excite in me, when I was first trying my own wings in short flights in ornithology, mostly confined to the vicinity of my home at Washington, by its appearance, nothing daunted, dur- ing the inclemency of October and March, whenits more delicate relatives were far away. Its very slender, pale-colored legs, like those of many other insect-eating birds which spend much 32 DISTRIBUTION OF THE HERMIT THRUSH of their time on the ground, always suggested that it was bare- footed, and tempted me to wonder why it did not suffer, ram- bling incessantly over the frozen ground, or even leaving its track in a slight fall of snow. Though I never knew it to en- dure the depth of winter in this locality, yet other observers have found it lingering through the whole season still further north — the Eev. Dr. Turnbull has left us such a record in his elegant little volume en titled " The Birds of East Pennsylvania and New Jersey"; and Mr. C. J. Maynard says he has seen the bird in Northern New Hampshire in November, when the snow was on the ground. Those who care to look farther into the details of the subject will find many other records, which show the whereabouts of the bird at various seasons, in my " Birds of the Northwest." Here, I will content myself with the further statement that it is chiefly known as a migrant in the Middle States, not pausing to mate and rear its young south of Massa- chusetts as far as we now know, — though I suspect that it will yet be discovered to nestle in some of the untried recesses of the Alleghanies. In the northerly parts of New England, and thence to the Arctic regions, the Hermit Thrush is at home in summer. Whether it ever reaches Greenland or not is uncer- tain. A Thrush is recorded from that country by the accom- plished Danish ornithologist Professor Eeinhardt, under the name of u Turdus minor Grn." ; but I believe that the actual reference in this case is to the Olive-backed. The same doubt attaches to a part, at least, of the quotations we have of the bird's occurrence in Europe; others, however, are undisputed, and the fact may be considered established that it occasion- ally deviates so widely from its established routes of migration. From the West, we have the testimony of two excellent ob- servers, to show that the Hermit Thrush reaches the Rocky Mountains. Mr. J. A. Allen and Mr. T. M. Trippe have each found it in Colorado, and ascertained that it breeds in that Territory, in the mountains, up to an altitude of at least 8,000 feet, How quietly and with what solicitude for privacy the nesting of the Hermit Thrush is accomplished ! Such care is taken to conceal its nest in the recesses of tangled undergrowth that few are the ornithologists who have found it. If Wilson, Nut- tall, or Audubon ever saw a nest, no one of them recognized its owner. The nests and eggs which they describe as those of the Hermit were certainly the Olive-backed Thrush's, the NEST AND EGGS OF THE HERMIT 33 only one which nests at any considerable distance from the ground and lays spotted eggs. And unless the Hermit has changed its choice of a summer home since Wilson and Audubon thought they had discovered its nest, it never bred in the southerly regions where they thought it did. But their mistake was not unnatural, since, singularly enough, neither of these ornithologists knew the difference between the Olive- backed and the Hermit Thrush — a distinction erroneously said by Dr. Brewer to have been first suggested by Professor Baird in 1844, as Swainson had discriminated the two with perfect accuracy, though under wrong names, in 1831. The manner in which the nest of the Hermit Thrush is built, its situa- tion, and the eggs, are all so similar to the Yeery's that one must detect the shy parents .themselves before being sure which has been found. The nest is built on the ground or near it, generally in some low, secluded spot; no mud is used in its composition, the whole fabric being a rather rude and inartis- tic matting of withered leaves, weed-stalks, bark-strips, and grasses — the coarser and stiffer substances outside, the finer fibres within. The cup is small in comparison with the whole size, owing to the thickness of the walls and of the base. The eggs are like those of the Kobin or Wood Thrush, in their uni- form greenish-blue color, but smaller, measuring about niiie- tenths of an inch in length by five-eighths in breadth ; being thus not distinguishable from those of the Yeery. I have never known of an instance, to my recollection, of the eggs being spotted ; but so many birds which usually lay whole-colored bluish eggs occasionally drop a set which are somewhat speckled that I should not be surprised to find at any time a Hermit Thrush's egg showing a few specks about the larger end. Great injustice would be done were the Hermit's musical powers overlooked in any sketch, however slight, of its life- history. The earlier authors were evidently unaware of its accomplishments, for its melody is lavished on the gloom of the swamp, or lost in the darkening aisles of the forest, where years passed by before the ear of the patient and toiling stu- dent of nature was gladdened by the sweet refrain. Wilson denies it song ; Audubon speaks of u its single plaintive note", though he adds, perhaps upon information received from his friend Dr. Pickering, that " its song is sometimes agreeable n. Nuttall seems to have first recognized the power and sweet- 3 B c 34 THE SONG OF THE HERMIT ness of the lay of our Hermit : he compares it to the famous Nightingale, that sweet princess of song, and ranks it far above the Wood Thrush. Later writers agree in this high estimate of the bird's powers, though it may be questioned whether a comparison unfavorable to the Wood Thrush is a perfectly just discrimination. The weird associations of the spot where the Hermit triumphs, the mystery inseparable from the voice of an unseen musician, conspire to heighten the effect of the sweet, silvery, bell-like notes, which, beginning soft, low, and tinkling, rise higher and "higher, to end abruptly with a clear, ringing intonation. It is the reverse of the lay of the Wood Thrush, which swells at once into powerful and sustained effort, then gradually dies away, as though the bird were reced- ing from us ; for the song of the Hermit first steals upon us from afar, then seems to draw nearer, as if the timid recluse were weary of solitude, and craved recognition of its conscious power to please. Yet it is but a momentary indecision — true to a vow of seclusion, the anchorite is gone again to its inviolate grotto in the fastnesses of the swamp, where a world of melody is wasted in its pathetic song of life : — "Full many a gem of purest ray serene, The dark unfathomed caves of ocean bear ; Full many a flower is born to blush unseen, And waste its sweetness on the desert air."

USTULATUS. — $ 2 Rufo-olivaceus j cceteris T. sicainson sat similis. This form is entirely like swainsoni proper, excepting in a rufous shade o the olive of the upper parts approaching that of fuscescens, from, which it is distinguished by the different tone and pattern of the coloration of the under parts. These characters, which it shares with swainsoni, distinguish it from alicice, no less than does the shade of the upper parts. It is simply the more rufous phase of swainsoni from the northwest coast region. T. alicicK is more decidedly different from swainsoni in the characters note above, and is held by many excellent ornithologists as a distinct species. The interrelationships are treated in my " Birds of the Northwest ", and more fully in the " History of North American Birds ". ONE of the most peculiar traits of the Olive backed Thrash is its erratic disposition. If not a greater vagabond than the Robin itself, this Thrush commonly wanders further south than any of its relatives ; its journeying into distant portions of South America being conspicuous. While the rest of our Thrushes which leave the United States in the autumn rarely if ever pene- HABITS OF THE OLIVE-BACKED THRUSH 37 trate beyond the Isthmus, the Olive-backed Thrash has ap- peared in Ecuador, Peru, and Brazil, as recorded by Sclater, Cabanis, and von Pelzeln, respectively. It likewise occurs in Cuba and in Greenland, and, like all our other Hylociclilcv, except- ing the Wood Thrush, has been reported from Europe. There is also a record of its presence in Siberia; though very possibly the actual reference in this case is to the variety alicice, lately accredited by Taczanowski to the same country. Its disper- sion over the eastern portions of North America is general. The southern limit of its usual breeding-range has been fixed by Dr. Brewer in Massachusetts, but I am under the impression that such restriction requires to be removed. I have mislaid a reference I once possessed to its breeding in Connecticut and in the mountains of Pennsylvania, and cannot now recall the authority ; but such extension of its range in summer agrees better with the accounts of some of the earlier writers as well as with what we now know of its distribution during the same season in the West. Late observations have informed us of its westward extension beyond the main chains of the Kocky Mountains. My correspondent, Mr. T. M. Trippe, found the bird in Colorado Territory in May and September ; and on one occasion in October, when the snow lay a foot deep on the ground, he observed it in company with various other species which had gathered about the Hot Sulphur Springs, in the Middle Park, apparently attracted by the warmth of these tepid pools. " In the vicinity of Denver," says Mr. H. W. Henshaw, "the species makes its appearance about the 10th of May; and by the 17th the thickets and partially open ground in swampy localities were fairly swarming with these birds. They were perfectly silent, and busied themselves after the usual manner of the family in scratching and seeking among the leaves for food. The males preceded the arrival of the females by at least a week." The most explicit accounts from the Far West are, however, those given by Mr. Eidgway, in his still unpublished Report on the Birds observed during Clarence King's Survey of the Fortieth Parallel. I quote from proof-sheets which he kindly placed at my service : " Swainson's Thrush is a very abundant species among the Wahsatch Mountains, and is, in fact, one of the most characteristic summer birds of that region. It there breeds plentifully in the canons, where its song may be heard almost continually during the nesting season Numerous nests were found among the thickets bordering the 38 HABITS OF THE OLIVE-BACKED THRUSH streams ; they were generally situated about five or six feet from the ground, in the willows or other shrubs, near the water." This paragraph leads me to speak at once of another pecu- liarity of the Olive-backed Thrush in comparison with all its congeners, excepting, of course, its two varieties alicice and ustulatus. I refer to its laying speckled eggs in a nest several feet from the ground. The Wood Thrush, indeed, builds in bushes and low trees ; but then its eggs are whole-colored, like those of the Yeery and Hermit, both of which nestle on or very near the ground. In high Arctic regions, whither many of Swain- son's Thrushes resort for the summer, the nest has been fre- quently observed on the stunted vegetation not a yard from the ground ; but, in more favored places, the altitude is usually about a man's height. The nest is more compact and more elaborately finished than those of the ground-builders, the Yeery and Hermit, the outer portions of which are coarser and less consistent. The material is very miscellaneous, and varies, moreover, with the locality 5 but mosses, lichens, leaves, bark- strips, and fibrous weedy substances are usually found, while in some the Hypnum mosses are said to be most conspicuous, and to give a distinctive character. In size, the nests are only about four inches in diameter by half as much in depth ; the walls being about half an inch thick. The eggs, numbering four or five, measure about seven-eighths of an inch in length by five-eighths in breadth ; but much variation, both in size and shape, has been observed. They are light greenish-blue in color, fully speckled with reddish -brown and other shades. Any Thrush's eggs like this found in a nest above the ground, described by early authors, were almost certainly those of the Olive-backed Thrush, to whatever species they may have been accredited. As to the general habits of this bird in comparison with those of its congeners, there is little to be said, since they are scarcely distinctive. It is perhaps less decidedly terrestrial and less solicitous of concealment than the Hermit, being often observed in open woodland, and gleaning much of its food among the branches of trees. 1 do not think that I have ever recognized its voice, excepting the short single note which is much the same as that of its allies. Dr. Brewer describes it as having a certain resemblance to that of the Hermit, yet quite distinct; " it is more prolonged ; the notes are more equal and SYNONYMY OF TURDUS FUSCESCENS 39 rise with more regularity and more gradually, are richer, and each note is more complete in itself. Its song of lamentation, when robbed of its young, is full of indescribable pathos and beauty, haunting one who has heard it long after."

I have not observed a very early spotted and streaked stage of plumage, which, however, is presumed to occur, as in other species of this group. The sexes are alike in color, and the seasonal changes are slight. The differ- ences consist mainly in the stronger reddishness of the upper parts, or its tinging with an appreciable shade of olivaceous. But the upper parts are never of the decidedly olive shade seen in swainsoni and in the fore parts of pallasi. The color of the upper parts, however, viewing its occasional shad- ing toward olive, is less strongly distinctive of the species than the peculiar coloration of the under parts is. The pinkish-buff of the jugulum, restricted and sharply contrasting with the white of the breast, and its few small brown (not black or even blackish) spots, which do not extend into the white of the breast, are perfectly characteristic, as are the absence of a decided yellowish orbital ring and of distinct streaks on the auriculars. A curious malformation is exhibited in a specimen in Mr. Ridgway's col- lection, in which the upper mandible is overgrown, and as much hooked at the end as that of a Shrike. The average dimensions of a large series of specimens of both sexes are : — Length, 7.35; extent, 11.75; wing, 3.90; tail. 2.85 ; tarsus, 1.12. WILSON'S Thrush is another species which, a few years ago, could not have been properly brought into the present connection, owing to our lack of knowledge of its ex- treme western limits. The first authentic record of its occur- rence in the*Rocky Mountains is, I think, that given in 1858 by Professor Baird, who received a specimen from Fort Bridger, Utah. Latterly, Mr. J. A. Allen found the bird in Colorado Terri- tory, where Mr. Trippe also observed it, in July, at an eleva- tion of over 8,000 feet, and where it was doubtless breeding. Both Mr. Ridgway and Mr. Henshaw discovered it to be an abundant species in Utah and Colorado, and the former re- garded it as one of the most characteristic birds of the valleys of the Provo, Bear, and Weber Rivers in Utah. Two nests were found by the latter near Fort Garland, Colorado, at nearly the altitude just mentioned ; one of them was curiously built above an old nest of the previous season, which had been remodeled for the purpose. As Mr. Henshaw remarks, though the Veery is thus common on the northern confines of the Colo- HABITS OF THE VEERY 41 rado Basin, no one appears to have found it in New Mexico or Arizona. It must consequently take a somewhat circuitous route in gaining its winter home in Central America, unless perchance it migrates at a considerable elevation along the mountain-chains. The latter supposition seems more probable, since Professor Sumichrast has observed it in Orizaba in Mexico. Its general northward dispersion appears to be more restricted than that of either the Hermit or the Olive-backed Thrush, being perhaps coincident with the limit of arboreal vegetation. In Cuba, it is one of the commoner species of the genus. A few linger through the winter in our Gulf States, but the majority leave our shores for the more genial climate of subtropical America, and proceed as far as Panama — in exceptional cases still farther, as in the instance noted by A. von Pelzelu, of an occurrence at San Vicente, Brazil, in December. There is even a record of the appearance of the bird in Europe ; but I under- stand that this is open to doubt. It will be seen that its dis- tribution is much like that of the Hermit and the Olive-backed, yet on the whole somewhat restricted, though less so than that of the Wood Thrush. Its breeding-range, similarly, is more southerly, approximating to that of the Wood Thrush ; it includes the Northern, Eastern, and some of the Middle States, and an adjoining belt of country in British America ; while in the Rocky Mountains it stretches southward to the confines of New Mexico and Arizona. The Veery's mating and nest building season, when the bird is in full song, is the genial month of May, in most parts of the United States ; and two broods may be reared under propitious surroundings. But further northward, where alobe have I my- self found the bird in its home, and beard its seductive epitha- lainium, the shorter span of the summer season suffices but for a single brood. The yearly crisis of the bird's life is delayed till June, and the young are not seen abroad till the latter part of that mouth, if indeed before July. The heavy growth of timber that fringes the streams includes many nooks and dells, and broken ravines overgrown with thick shrubbery, from out the masses of which the tall trees tower, as if stretching forth their strong arms in kindly caressing of the humbler and weaker vegetation, their offspring. In such safe retreats, where the sombre shade is brightened here and there with stray beams of sunlight, in the warmth of which myriads of insects bathe their wings and flutter away their little span of life, 42 NESTING AND SINGING OF THE VEERY humming a quaint refrain to the gurgle of the rivulet, the Veery meets his mate — the song rises — the wooed is won — the home is made. Should we force our unwelcome presence upon the bird who is brooding her newly-found treasures with the tenderest solicitude, she will nestle closer still, in hope of our passing by, till we might almost touch her; when, without a word of remonstrance or reproach, she takes a little flight, and settles a few yards away, in silent appeal. If the time, the place, the scene, suffice not for our forbearance, with what poor words of hers may we then be moved ? The nest will be found at our feet, most likely beneath some bush, resting upon a bed of leaves, or supported in the forks of some stems that spring directly from the ground. It seems large for the size of the bird, and perhaps not so neat and finished as we might expect ; for the Veery, though a patient and faithful housekeeper, cares little for appearances. Among the various materials which enter into its composition, withered leaves form a large part, especially of the outer walls, while grass-stems, weed-stalks, and bark-strips are more compactly woven inside. There is no special lining of the interior, and the cavity is small. The nest may contain four, perhaps five, eggs, like those of the Hermit, greenish-blue, without markings, except in rare instances, when a few specks appear, especially about the larger end. Varying estimates have been made of the Veery's powers of song. For myself, I rate this bird as one of the sweetest of our songsters, of whose " clear bell-like notes, resonant, distinct, yet soft and of indescribable sadness", I have spoken on a former occasion. I think Dr. Brewer's faint praise the most cruelly unjust of all ; can he have ever heard the Veery's full utter- ance, and then have written, " The song of this thrush is quaint, but not unmusical ; variable in its character, changing from a prolonged and monotonous whistle to quick and almost shrill notes at the close" I He speaks as he might of a hurdy- gurdy, instead of an exquisite oboe. No one of the voices of the woodland is less quaint than the Veery's ; no one is truer to its theme, more measured in its cadences, or softer and .clearer in tone than that of the Veery— rival of the Olive, the Hermit, and the Wood Thrush, completing the quartette of silver-tongued cantatrices, who pledge the promises of spring- time in choral symphony. CHARACTERS OF MYIADESTIN^E 43 SUBFAMILY MYIADESTINJE FLYCATCHING THRUSHES The essential character of this group has been indicated on a preceding page. It has usually been associated with Ptilo- gonys and Phccnopepla in the family (Ampelidce) which contains the Ce- dar Bird and Bohemian Wax wing; from all these birds, however, the boot- ed tarsi, speckled state of the young, and other char- acters sufficiently distin- guish it. In comparison with the Thrushes, among which it is now located, it differs in the shorter, broader, more depressed, and flycatcher-like bill, with its deeply-cleft ric- tus and very short gonys, the smaller and weaker feet, and in the peculi- arly double - inarginatC FlG.5.__DetailS of external form of Myiadestes (M. tovn- tail, the feathers of which sendi) • bil1 and feet natural 8ize ; win& an<* tail *• taper gently from base to tip. It is a small group, nearly con- fined to the warmer portions of America, comprising only two or three genera, the leading one of which is the — Genus MYIADESTES, Sw., which was established by Mr. William Swainson, in 1838, in his arrangement of the Flycatchers, a work forming part of Sir William Jardine's " Naturalists' Library ". It consists of ten or twelve species, only one of which occurs within our limits, the others being more southerly. In addition to the characters just noted, it may be observed that the species of Myiadestes agree in their rather uniform dark or dull coloration, variegated with brighter tints on the wings. They form part of an interesting 44 CHARACTERS OF MYIADESTES TOWNSENDI and somewhat isolated group, having no very intimate rela- tions with the other birds of our country, inhabiting woodland and shrubbery, feeding on insects and berries, and capable of musical expression in an exalted degree.

In pen- ning an account of this stranger for the " Birds of the North- west7', I could only state that I had found it rather rare, in sum- mer, in the upper portions of Arizona, and gather from my cor- respondents, or from the published records of other observers, some items of its life-history. I would refer to this article, however, as a fair epitome of what was then known, and, avoiding repetition, can now supplement it with some further particulars, the principal of which relate to the nidification of the species. None of the earlier observers appear to have ever found the nest of this bird ; and to this day the eggs remain unknown. A few years ago, however, Mr. Ridgway discovered a nest, an account of whiclj was communicated to Dr. Brewer, and pub- lished in substance in the work above quoted. The original notice, as prepared and printed (but up to the date of present writing, February 8, 1876, remaining unpublished), I am able to quote through the kindness of the writer, who has placed at my service the proof-sheets of his report on the birds observed during the Exploration of the Fortieth Parallel by Clarence King: — " In July, 1867, we found a nest of this species in a deep ravine on the western slope of the Sierra Nevada, at an alti- tude of about 5,000 feet. This nest was placed in a cavity of the rocks forming the perpendicular upper bank of a sluice, constructed for mining purposes, and through which ran the water of a considerable mountain-stream. The nest, which was about a foot above the water, was nearly as bulky as that of the Brown Thrasher (Harporliynclms rufus), and similarly con- 46 HABITS OF TOWNSEND'S FLYCATCHING THRUSH structed ; it contained four young. When we approached it, the female was much excited, flying before us or running upon the ground in the manner of a thrush, a species of which she was at first thought to be, from her entirely thrush-like man- ners and appearance. Even afterward, and until the species was identified by obtaining specimens, we were led into this delusion, its gliding, noiseless flight, and graceful running upon the ground being so perfectly thrush-like." This curious fact, which would never have been anticipated, of the nesting of the bird in the rifts of rocks, is corroborated by the later observations of Mr. Henshaw, whose article, as pre- pared for the zoological volume of the Reports upon Explora- tions West of the One Hundredth Meridian — a work which will doubtless issue from the press during the present year — is to the following effect: — During a week's stay in June, at the base of Baldy Peak, in Colorado, he frequently saw this bird in the pine forests, and as high up on the mountain sides as 10,000 feet ; its summer range doubtless extends up to timber line. Its habits, as far as he noticed them, are singularly like those of the Bluebirds. Besides a loud, liquid call note, the male has a beautiful warbling song, which somewhat resembles that of the Purple Finch, but far excels it in power, sweetness and modulation. Though he searched carefully for the nest, he cnly succeeded in satisfying himself that the bird breeds in the crev- ices of rocks. Its preference for such localities during the sum- mer, with the evident solicitude manifested on more than one occasion, left little doubt in his mind on this point. The birds are quite common (Mr. Heushaw continues), in the fall, in Eastern Arizona and Western New Mexico. Having reared their young, they appear to forsake the pine woods, which constitute their summer abode, and are seen lower down, on the hillsides covered with pinons and cedars. Their food at this season appears to consist almost exclusively of berries, particularly of the pinons and cedars, and the crops of many examined contained little else save a few insects. Though in summer a bird of retiring and unsocial habits — never more than a single pair being found in one locality — in the fall they are to a considerable extent gregarious, associating usually in small companies of from five to ten. At the Old Crater, forty miles south of Zuni, they had congregated in very large numbers about a spring of fresh water, the only supply for many miles around ; and hundreds were to be seen sitting on the CHARACTERS OF THE MIMING 47 bare volcanic rocks, apparently too timid to venture down and slake their thirst while we were camped near by. Their song is occasionally heard even in November and December, and is very sweet, but not so full and varied as during the vernal season. The sociable disposition which Townsend's Thrush manifests during the winter, contrasting with those traits it shows at other seasons so conspicuously that it has acquired the soubri- quet of u Solitaire ", is also attested by Mr. J. K. Lord, from observations made at Colville during November, when the leaves had fallen, snow covered the ground, and the cold was intense. His attention was attracted by the sound of singing, unusual at that inclement season ; and he soon discovered a score of these brave little birds perched upon the sprays of some thorn-bushes, and was reminded, by their low, sweet notes, of the Song Thrush of Europe. Commend me to the rare bird that sings in winter, whose pipe, yet limpid when the rivers cease to flow, is tuned to sounds harmonious amid the discord of the elements, in earnest of more genial times to come ! SUBFAMILY MIMING : MOCKING THRUSHES CHARS. — There is little to be added to the comparative diag- nosis of this group already given (p. 5). The tarsi are scutellate anteriorly, with seven scales (rarely obsolete, as sometimes oc- curs in Galeoscoptes). The wings are short and rounded — usually shorter than the tail, the feathers of which are graduated in length. There are bristles about the base of the bill, but the feathers themselves are soft. The bill is extremely variable in length and shape ; sometimes it is much shorter than the head, and as straight as that of a typical Thrush, but in other cases it equals or exceeds the head in length, and is bent like a bow. The members of this group have been sofnetimes classed with the Wrens, to which they bear a strong resemblance in many respects. They are peculiar to America, and abound in species in the warmer parts of this hemisphere. In its broader features, the economy of these birds is much the same as that of the true Thrushes. They are insectivorous, but also feed on various soft fruits. They inhabit shrubbery rather than high- open wood- land, and as a rule keep nearer the ground, some of the species being decidedly terrestrial, as indicated by their large strong feet. Their nidification is inartistic ; the stout bulky nests are 48 CHARACTERS OF THE GENUS OROSCOPTES placed in bushes ; the eggs are three to six in number, usually speckled (the Catbird furnishes an exception to this last state- ment). In this group, the vocal powers are carried to the highest known degree, some of the species being able to imitate not only the notes of other animals, but various sounds which are mere noises, without' musical quality. There are three Xorth American genera of this subfamily, all of which are represented in the Colorado Basin. Although the generic characters are not very strongly marked (all the species used to be placed in the single genus Mimm), tangible differ- ences will be observed on comparing the diagnoses given. Genus OROSCOPTES Baird CHARS. — Wings and tail of equal lengths, the former more pointed than in the other genera of Mimince, with the first quill not half as long as the second, which is between the sixth and seventh ; the third, fourth, and fifth about equal to each other, and forming the point of the wing. Tail nearly even, its feathers being but slightly graduated. Tarsus longer than the middle toe and claw, anteriorly distinctly scutellate. Bill much shorter than the head, not curved, with obsolete notch near the end. Eictal bristles well developed, the longest reaching beyond the nostrils. 0. montanus is the type and only known species of this genus. Mountain Mockingbird Oroscoptes montanus OrphCUS montanus, Orn.

Young : Dull brownish above, conspicuously streaked with dusky ; the markings below streaky and diffuse. Specimens differ little with sex or season, or with age after the first streaked stage is passed. The individual variation consists in the purer or more brownish ash of the upper parts, and especially in the shade of the under parts, which ranges from whitish to a decided browuish-ciunamon cast, and in the amount of spotting. Ordinarily, the lower belly and vent, and sometimes the throat, are immaculate, but the whole under surface is sometimes pretty uniformly covered. The brownish shade is usually strong- est on the breast, flanks, and crissum. The newly-grown quills and tail- feathers are darker than the old ones, and have more white edging. The wing-coverts are sometimes edged as well as tipped with white. THIS interesting species resembles a Mockingbird — espe- cially a young one, before the spots on tbe under parts are lost — in many respects, but differs altogether in the quality of its song, and shares much of the ground-loving nature of a *Sincc these references to Messrs. Yarrow and Henshaw's writings (which are important in the present connection) may not be generally understood, it should be stated that " Rep. Orn. Specs." refers to a pamphlet (8vo, pp. 148) published at the office of the United States Geograph- ical and Geological Explorations and Surveys West of the One Hundredth Meridian, under auspices of the Engineer Department of the United States Army, relating to the collections made by the gentlemen named in 1871, 1872, 1673, containing five separate papers, one of which is an ' ' Annotated List of the Birds of Utah ", republished from Ann. Lye. N. H. New York, xi, 1874 ; and that "List B. Ariz." refers to a paper by Mr. Henshaw in Appendix LL of Annual Report of Chief of Engineers of the United States Army for 1875 ; the pagination being given accord- ing to the separately-printed pamphlet edition of this Appendix (8vo, pp. 196). These papers are full of interesting field-notes, and bear directly upon the subject in hand. 4 B C 50 MIGRATION, ETC., OF THE MOUNTAIN MOCKINGBIRD Thrasher. It was one of the birds discovered by Mr. J. K. Townsend, who, with his some time companion Nuttall, explored the region of the Columbia, bringing many ornithological novel- ties to light. aSTuttall speaks of its pleasant song, which he says resembles that of the Thrasher, and ascribes to it powers of imitation ; but as his statement of such ability has not been since corroborated, we are left to infer that it possesses nothing beyond the flexible modulation of the voice for which all its tribe are famous. He discovered a nest, situated in a worm- wood-bush, containing four eggs. The original accounts of the species constituted the sum of our information respecting it for many years, until the general opening-up of almost untrod- den wastes put other eager and curious observers upon its track. From what we have learned, it would appear to have been mis- named the Mountain Mockingbird, since, as has been intimated, its repertoire is not remarkably extensive, while its favorite haunts are the arid and desolate sage plains of the great cen- tral plateau. We are now pretty well acquainted with its geographical distribution, though more precise knowledge of its movements would be acceptable. It is migratory, like most of its tribe, but only within a limited area. It is known to be resident in Texas, where my friend H. E. Dresser, of London, observed it at San Antonio and Eagle Pass in winter and sum- mer, and where he procured the eggs. He found it, like others, in brushy plains, and noticed its terrestrial habits. As well as I can judge from the accounts to which I have referred for in- formation— having nothing original to present upon the subject — the bird offers one of the many instances of what I should call " migration at will", if I dared to propose a sort of paradoxical term. That is to say : out of the sum-total of individuals com- posing the species, congregated in their winter haunts, a cer- tain percentage elects to go north in the spring, dropping loi- terers by the way, while the rest breed where they wintered. In this manner, the species spreads latitudinally until the limit of its dispersion, which cannot be far from the northern bound- ary of the United States, is reached, and may be found nesting anywhere within the area it inhabits. In the fall the return movement is accomplished, and the species is then withdrawn into its comparatively narrow winter quarters, the limits of which I believe remain to be ascertained. This kind of optional or elective migration, witnessed in many other cases besides the present one, contrasts with the regular migration perforce HABITS OF THE MOUNTAIN MOCKINGBIRD 51 of those other species, all the individuals of which are mysteri- ously impelled to journey toward the pole, and settle for the summer in areas perhaps more contracted than their winter homes. For the general habits of this species I shall presently quote Mr. Ridgway, who has made good use of the favorable oppor- tunities he enjoyed ; but- will first describe the eggs, which I have examined in the [National Museum at Washington. The clutch usually numbers four, measuring from 0.94 to 1.03 in length, and from 0.69 to 0.75 in breadth (inches and decimals). The ground-color is light greenish-blue ; this is heavily marked with burnt-umber or olive-brown spots, and a few others of neutral tint. The pattern is generally bold and sharp, but in some cases finer and more diffuse, when the numberless speck- les and dots give an effect similar to that of some styles of Mockingbirds' eggs. Instead of collating the fragmentary notices of writers who have recorded their transient impressions or isolated observa- tions, I shall conclude the history of the Mountain Mocking- bird with an extract from the author last mentioned. [Noting that it inhabits sage-plains, especially of the '-Great Basin", and suggesting the name " Sage Thrasher " as more appro- priate than " Mountain Mockingbird", Mr. Kidgway goes on to say, in his note-book now lying before me: — " Carson City, Nevada, March 24, 18G8. — To-day we saw the Sage Thrasher for the first time this spring, and heard its song. The sage-brush was full of the birds, and many were singing beautifully when the evening shades were lengthened by the sinking of the sun behind the Sierras. Owing to the earliness of the season, the song was uttered in a subdued tone, and its full merits could not be appreciated. The bird was generally seen sitting in an upright position upon a sage bush, but when approached would dive — apparently into the bush, though close examination failed to reveal its hiding-place ; often, however, we again heard it sweetly warbling, perhaps a hundred yards away in the direction from which we had come. This con- cealed, circuitous flight is characteristic of the species. u April 2.— Rained throughout the night; this morning the air is fresh and balmy ; clouds are lowering about the bases of the mountains, concealing them from view. The air is vocal with the music of the spring birds, singing with vigor and joyousness. The Meadow Larks are singing throughout the 5*2 SONG AND NEST OF THE MOUNTAIN MOCKINGBIRD sage-brush, and with their rich notes are heard the sweet \varb- lings of Oroscoptes montanus. To-day we heard this song in all its loveliness. Although weaker than that of either the Brown Thrasher or the Catbird, it is more varied and longer sustained as well as superior in sweetness and delicacy of tone. The song has, in modulation or style, a great resemblance to the soft tender warbling of th3 Ruby-crowned Kinglet, although it is stronger, of course, in proportion to the size of the bird. "April 9. — The. Sage Thrasher is now one of the most com- mon birds in this vicinity. To day a great many were noticed among the brush-heaps in the city cemetery. Its manners dur- ing the pairing season are peculiar. The males, as they flew before us, were observed to keep up a peculiar tremor or flutter- ing of the wings, warbling as they flew, and upon alighting (generally upon the fence or a bush), raised the wings over the back, with elbows together, quivering with joy as they sang. "April 23. — Although we saw tbese birds everywhere among the sage-brush, their nests were found only with great diffi- culty. In the cemetery, the sage bushes had all been pulled up and thrown in piles in different parts of the inclosure, and upon these the birds were most frequently seen. On one occa- sion, a female was observed to fly into one of these brush-heaps, with a bunch of building material in her mouth ; but it was only by taking off bush after bush that the nest was discov- ered; this, though unfinished, contained one egg, and, in its construction and situation, resembled some of the nests of the jChrasher, though less bulky. The bushes were carefully re- rplaced, and the nest left undisturbed. In walking through the ;sage-brush on the open commons, several more nests were found, in similar situations, being placed in the thickest por- tion of the bushes, generally about two feet from the ground, but occasionally imbedded in the ground beneath them. They were all well concealed. At one time, while blowing some eggs, the parent birds came near us, running gracefully upon the ground in the manner of a Eobin, stretching their necks, curi- ous to see what we were doing, and watching our movements with an anxious look, but uttering no note whatever. " The only note of this species, besides its song, is simply a weak '-tuck1, seldom uttered unless the young are disturbed; except during the pairing and nesting seasons, it is one of the .most silent birds with which I am acquainted. In September I saw it feeding upon the ' service-berries,7 which grew abund- antly in certain localities at the foot of the mountains." MIMUS— SYNONYMY OF M. POLYGLOTTUS 53 Genus MIMUS Boie CHARS. — Bill inucli shorter than the head, scarcely curved as a whole, but with gently curved commissure, notched near the end. Kictal vibrissre well developed.
