IV DISTRIBUTION THE fact that birds are not universally distributed is known to every one interested in natural history; that the Mock- ingbird is a southern, and not a northern bird is generally understood. The exact limits of the breeding area of any one bird are hardly to be defined even in New England, but the region where it breeds commonly may now be definitely mapped. Two important factors must be borne in mind in studying the breeding areas of the birds of New England and New York: the latitude and the altitude. If we pass from New York city through southwestern Connecticut to New Haven, then up the Connecticut Valley to northern Vermont, we note in southern Connecticut the tulip-tree and the sweet gum; in central Connecticut we see them no longer, but we still see oaks and hickories; but by the time we reach Wells River in central Vermont, these too are left behind, and patches of spruce and fir appear on the distant hillsides. We have climbed only 407 feet from the sea, but we have traversed nearly three degrees of latitude, and hence these changes. They are due to a colder and moister climate at a higher latitude. Had we left the train in the Connecticut River Valley, at Greenfield, traveled westward to North Adams, and then climbed Mt. Greylock, almost 3000 feet above the railroad, we should have noted the same changes as we ascended the mountain; the oaks and nut trees would have disappeared, and been replaced by spruce and fir. But here the changes would have been due to altitude. 14 A GUIDE TO THE BIRDS And as all life is intimately associated, the student of birds would have felt sure from the presence of the sweet gum trees in Fairfield County, Conn., that certain birds, the Southern Water-thrush for example, would be found breed- ing there, and from the spruces on Greylock or in northern Vermont, that Black and Yellow Warblers nested among them. To predict what birds will be likely or certain to be found in any one place, we must, therefore, know first its lati- tude, — southern Connecticut and northern Maine will have few birds in common; next, we must know the altitude of its hills and the character of their vegetation, —if they are high enough to be clothed with spruce, they will be frequented by birds unknown as summer residents in the lowland. So regularly do certain groups of plants and animals, in- cluding birds, confine themselves to certain well-marked re- gions, that it has been found convenient to employ certain fixed terms to designate the areas where these groups are found. The sweet gum and the Southern Water-thrush are characteristic of the Atlantic Plain from southwestern Con- necticut to Florida; they are representatives, therefore, of what is known as the Carolinian or Upper Austral Life Zone. The spruce and the Black and Yellow Warbler occur through- out the forested region of Canada; they are representatives, therefore, in northern New England of the Canadian Life Zone. So closely is the presence or absence of a certain well- marked group of birds correlated with the presence or absence of the spruce and fir, that the nature of the forests becomes the first point one must settle with regard to any locality in southern New Hampshire or Vermont, or northern Massa- chusetts or New York. The accompanying map shows the extent in New England of the Upper Austral and Canadian Life Zones. The country between these zones possesses many birds 445 b Hartford -j AF Springfield y Chatham Canadian Cc Transition or Alleghanian Fr Upper Austral or Carolinian Attention is called to the fact that the Transition Zone extends up certain river val. leys as indicated on the map. For lists of species breeding in these zones see Appendix, page 341, 44 42 73 Longitude West 71 from Greenwich LIFE ZONES 16 A GUIDE TO THE BIRDS found in each of the neighboring belts, and none not shared by one or the other of them. It has therefore been called the Transition Zone. Tts boundaries to the north concern us chiefly, for many birds (see p. 342) cease to be found when we pass from this Transition belt to the Canadian. Nothing is sharply defined in nature, and so the bounda- ries of these zones, though they may be well defined on maps, have in the actual country a very indefinite outline, one area fading almost insensibly into another. Moreover, certain birds, though confined to the spruce belt, begin to appear at its very margin, while others demand for a summer home deep spruce forests, or other conditions which are attained only well within the belt. Snowbirds, for instance, usually appear with the first small patches of spruce, in Worcester County, Mass.; Brown Creepers only in large-sized spruce forests, such as occur on Greylock and Monadnock; and Black-poll Warblers not until the Catskill or White Moun- tain region is reached. Similarly, some of the Carolinian birds, such as the Chat and the Orchard Oriole, are found beyond the range of the others, far up the Housatonic Val- ley or in eastern Massachusetts. The range of any particular bird in the breeding season will be found in the account of that bird; in many cases the map which shows the Life Zones will give the area through- out which the bird commonly occurs. Outside this area, the bird may be expected to occur sparingly, in places which approximate to the warmth or dryness of more southern re- gions, or to the coldness and moisture of the north. Certain lists given in this book (p. 341) should be studied in this connection, and a list isalso given on p. 348 of “ local lists” which may be either bought, or obtained in large libraries; these give the latest information as to species found breed- ing in the various localities of which they treat. The student cannot be too strongly urged to make out for himself, by the use of the map and of the lists above mentioned, a list DISTRIBUTION 17 of the species which may be expected to occur in summer in his locality, and to annotate it, by reference to this Guide, with notes as to the abundance of each species, the kind of country it frequents, and the best field-marks by which to recognize it. He will then be able, when he begins his work in the field, to eliminate a large number of birds from consideration, and save himself from an embarrassment of tiches. Vv HINTS FOR FIELD WORK Any time of year is good to begin the study of birds, though February is perhaps tho best time. The number of species to be found in winter is so limited that a beginner can become familiar beforehand with the appearance and favorite haunts of those he is likely to find, so that he will welcome by name the first Golden-crowned Kinglet or Brown Creeper that he sees. The latter part of August and the first half of Septem- ber, except at the sea-shore, is perhaps the worst time of year for students of birds. Birds are then silent and retiring ; one sees few species, but must distinguish them from among a far larger number of candidates than in winter. Morning, as every one knows, is the best time of day to see and hear birds, but it is not necessary to rise at three or four, unless one wishes to accomplish a great deal in a morn- ing. If one starts before eight there will be, even in sum- mer, two or three hours when birds are fairly active. Be- tween five and seven in the afternoon there is a renowal of song and activity. A high wind, or a steady northwest wind in spring, makes a poor bird day; birds are then silent and retiring, A violent rain, of course, keeps them under cover, but they delight in warm showers. The first impression a beginner gets on a spring morning is of a confusion of sound, and if he attempts to find the individual songsters, he is often discouraged by the brief glimpses he gets of some distant and departing bird. An experienced student has in the mean timo noted the songs of many species, and recognized old frionds by a hint of color, HINTS FOR FIELD WORK 19 a trick of flight, or some mysterious general effect. Let the beginner patiently continue his walk, keeping, if possible, near mixed growth of trees or bushes, especially near water. Before long he will come upon some bird, or group of birds, busily occupied in feeding, or startle one from the ground to a neighboring twig. Now is his opportunity; if the bird is in good view, let him seize opera-glass, note-book, and pencil, and note everything possible about the stranger. On every walk, though the great majority of birds will tantalize a beginner by their restlessness, some one will favor him with a chance for leisurely survey, and a cataloguing of all its markings. It is frequently possible to draw birds out of thick cover by kissing the back of one’s hand, so as to produce a squeaking sound. After the student has learned the commoner birds, he should begin following up strange sights and sounds. Often the chase is long and futile; but generally, by cautious and persistent stalking, one brief glimpse after another yields the desired total. A new song should be followed to its source and the singer noted. I have then found it helpful to set down in syllables what the bird seemed to my ear to say. This habit not only trains one’s ear but also aids in fixing the song, so that it can be recalled. The secret of rapid progress lies, as in all things, partly in native talent, a quick eye and ear, and a retentive memory, but also in preparation. Each new week in the year, each new place one visits, should be read up beforehand, as one reads up a city in a guide-book. If April is approaching, look through the key for April, and note that one of the Warblers that is now to be looked for has yellow under parts, wags its tail, and has a song like that of the Chipping Sparrow. If besides, one has an opportunity to visit a large museum, and to see the mounted bird, one will have a men- tal image that will often make instant recognition possible. The study of good drawings of the birds is the next best 20 A GUIDE TO THE BIRDS preparation. The reading of books like those of Bolles, Burroughs, and Torrey is a great aid, as well as a pleasant stimulus. Opera-glasses are almost indispensable. The best for bird study magnify about three and a half times; in other words, the bird is brought that much nearer to you. The Zeiss glasses magnify many more times, and commend themselves by their small compass and large field. For sea-birds which are riding the water in one place, a powerful marine-glass or even a small telescope is useful. Note-books are indispensable, and it is often well to carry a handbook into the field, so that a bird can be looked up on the spot, and some important point settled, if possible, by examining the bird again and again. It soon becomes evident to a student that birds are much more plentiful in some spots than others. Often one can learn from others where the best places are; if not, one should try the edges of broad valleys, or the borders of streams where bushes, swamp, and pasture alternate. As a rule, the more diversified the country, the more birds there will be. In winter, warm sheltered hollows are attractive. In migration time it is particularly important to find favor- able places. When a student gets far enough to get the nesting fever, he has an endless and intense pleasure before him. The nest- ing season treads fast on the heels of the spring migration ; many birds, in fact, have built before the May migrants come. To find nests it is necessary to have found them ; that is to say, after one has been found, it is much easier to find the second, for one knows then where to look. One must, moreover, be constantly on the alert for the slight hints which are often so important. A bird going to and from its nest slips along in a very different fashion from its ordinary careless wandering, A straw or bit of hair in a bird’s mouth is a broad hint; sit down at once, and try to beat the bird at a waiting game, HINTS FOR FIELD WORK 21 The capacity to take hints grows by practice, as the powers of the eye and ear grow. The rapid identifications of the expert seem marvelous at first, but a beginner soon learns to tell a flying Goldfinch as far as he can see it. As season fol- lows season, his eye, ear, and memory serve him better and better, and at last he too walks through woods and fields, hearing and recognizing distant calls or bits of song, or iden- tifying the passing birds by a glimpse of some well-known bit of color, or by some marked peculiarity of flight. VI HOW TO USE THE KEYS Tue following keys include all the common land-birds of New England and eastern New York, except the hawks, the owls, the Mourning Dove, and the game-birds. No one should, however, expect, by the use of these keys, to name with certainty every small bird seen for a few moments at long range or in thick foliage. If a bird is to be identified, it must have been observed clearly enough and long enough for a fairly good description of it to be set down. No one can hope at first to carry an accurate mental picture of even the brightest bird. A note-book should, therefore, be always at hand in the field, and when an unfamiliar or doubtful bird is seen, the size, colors, habits, and habitat should be set down. Note-books arranged for such use can be procured (see list, p. 350). To estimate the size, compare the bird with an English Sparrow, which is about 6.33 inches long. The Song Spar- row is about as long as an English Sparrow; the Bluebird, a little longer. The Robin, about ten inches long, will serve as a standard of comparison for the larger song-birds. Birds are classified in the keys, according to color, under the following heads : — 1. Brown or Brownish (including reddish-brown). 2, Gray or Grayish (including greenish-gray). Thave excluded from both of the above classes any birds which show any clear, bright yellow, such as the female Maryland Yellow-throat, or marked bluish-gray, such as the HOW TO USE THE KEYS 23 Nuthatches, but have included birds that have a more or less faint yellowish wash on the flanks, as the Phebe in fall, and some of the Vireos. 3. Yellow or Yellowish without Black. (No large or prominent area of black.) 4. Yellow or Orange with Black. This class includes chestnut and black. The black appears either in streaks, as in the Prairie Warbler, or in patches, as in the Goldfinch. 5. Black and White. The black and white should form a marked contrast, either in streaks or bars, as in the Black and White Warbler and the Downy Woodpecker, or in large distinct areas, as in the Kingbird. 6. Black or Blackish. This class includes purplish-black, as in the Crow Black- bird and the Purple Martin. 7. Red, Scarlet, or Rose. This class includes all birds that have any such tint at all prominent. 8. Blue or Bluish-gray (excluding purplish-black). A number of birds have been put into more than one class, to guard against oversight, on the part of the observer, of some bit of color. Plain-colored females and young, and bright-colored males of the same species have, of course, been put into separate lists. For the summer months there is a key to the birds seen constantly on the wing, such as the Swallows and the Swift, without reference to their color. One should also notice carefully any conspicuous patterns of coloration, any stripes, streaks, or contrasts of color, and where they are situated. Many keys are based chiefly on such marks, and they are often necessary for final identi- fication. But some of them are often either overlooked by beginners, or not well displayed by the bird. More 24 A GUIDE TO THE BIRDS stress has been laid in these keys on a combination of char- acteristics than on any one set, nor need the failure to note any one mark block the student’s way entirely. After the size, general color, and conspicuous marks have been noted, one should observe any tricks of attitude or gait, such as hopping, walking, tilting the tail, bobbing the head, raising crest-feathers, etc. The bird’s feeding habits are also important; one should note whether it scratches for seeds, flies out into the air after insects, or gleans them from the trunk or twigs of trees. Lastly, one should notice the kind of country in which the bird is seen, whether marsh, meadow, orchard, thicket, or forest. The term plantation is used occasionally in this Guide to designate ground which has been planted with trees and bushes, as on large estates. It is important, in noting the locality where a bird is seen, to look about and see what kind of ground is found near by; a marsh a few rods away will explain the presence of a Red-winged Blackbird in a roadside tree. In times of heavy migration, it is true, a bird may appear almost anywhere, and Swamp Sparrows will turn up in backyards; but, as a rule, the nature of a bird’s food forces it, even in migration, to show preference for cer- tain haunts. When a beginner grasps the fact that he will never see a House Wren clinging to a bulrush, or a Marsh Wren in an apple orchard, he may do much in the way of eliminating improbable birds. Another important and much neglected means of assistance in identification is afforded by taking into account the time of year : certain birds are never here in January (exceptions, of course, occur, but may be ig- nored by the beginner); others are found only in winter.’ The keys have therefore been arranged so that each season has its own key, and reference should be made only to that; it will sometimes happen, however, that a bird will appear late in one month, though it regularly comes early in the next, and is provided for in the following key. HOW TO USE THE KEYS 25 Under the seasonal heading, there are subdivisions accord- ing to color, as already described, and in them the birds are arranged in two groups, in the order of their size: Group A contains birds larger than an English Sparrow ; Group B those smaller than an English Sparrow. As a further help in identifying the larger song-birds, the place in the list where a Robin would come is indicated. If the student be in doubt whether a bird be larger or smaller than an English Sparrow, let him study the last birds in Group A, and the first in Group B. If the bird be noticeably small, let him begin the search at the bottom of Group B. The divisions A’ and B/ are to be used only in southern Connecticut and in the lower Hudson Valley ; the divisions A” and B” only in the north- ern portions of New York and New England. An asterisk beside the figures which give the size of a bird, indicates that the bird does not occur every year; two asterisks mean that it is very irregular, and more often absent than present. The figures in the keys indicate in inches and decimals the length of the bird ; the keys include, besides, a brief state- ment of the kind of country in which the bird is generally found, and brief clues for its identification, — some strik- ing field-mark, or constant trick of action. If the bird has been carefully watched under favorable conditions, the search in the key will soon narrow down to a small number of spe- cies. If there is still doubt, the descriptions of these species and the accounts of their habits given in the body of the book should be carefully read, the evidence weighed, and a final choice, if possible, be made. A common fault of be- ginners in identifying from printed descriptions is to ignore some perfectly obvious and insuperable objection. I have known the skin of a Brown Thrush labeled as a Cuckoo, in spite of its spotted breast. Mr. Chapman tells me that the Louisiana Water-thrush has been identified as the Olive- backed Thrush : one is 6.28 inches long, the other 7.17; the extra inch must tell, even in the ficld. 26 A GUIDE TO THE BIRDS But birds are often not seen to advantage; it is hoped that in such cases students of this book will learn to be con- tent with the belief that the puzzling bird was probably one of two or three, and wait for another opportunity to settle the matter. No method is more harmful to a real advance in knowledge than the anxiety to get some name or other for every bird seen. The best field ornithologists of my acquaintance are most distinguished by their reluctance to give a decision on insufficient evidence, Yet one can be too timid, and a habit of doubting one’s own powers of observa- tion leads to discouragement. If one has a description noted on the spot, it is good mental training to come to some defi- nite decision, to say that the weight of evidence is strongly in favor of this or that species. Certainty will come in time, with widening acquaintance. The beginner must realize, too, that his powers of observation are probably not yet fully de- veloped; his untrained eye is confused by a flying or mov- ing bird, and gets only a glimpse of color, where a skilled observer sees steadily, and discovers the distinctive field- mark, KEYS KEYS Nore. — The following signs and abbreviations are used in the keys and in the text: — gd = male. Im. = immature. 9 = female. * = irregular. Ad. = adult. #** — very irregular. Groups A (birds larger than an English Sparrow) and B (birds smaller than an English Sparrow) may be used throughout New England and eastern New York; groups A’ and B’ only in southern Connecticut and the lower Hudson Valley; groups A” and B” only in the northern portions of New York and New England. (See p. 25.) No provision has been made in the keys for birds in immature plumage; in the autumn and winter in most cases where the female (?) is specified, young males may be included in the same category. The occasional dates of arrival or departure given in the keys are, of course, only approximate, and will vary according to the season and to latitude. One may also expect a variation of about ten per cent. each way in the lengths of birds given in the keys and text. KEY FOR WINTER Brown or Brownish. A. 12.00. 10.75. 10.00. 7-75- 7-19.
