# A Synopsis of the Birds of North America

John Audubon

## PREFACE

I have been induced to present this Volume to the Public by two considerations. The figures and descriptions contained in the works entitled “The Birds of America,” and “Ornithological Biography, or an Account of the Habits of the Birds of the United States,” having been issued in the miscellaneous manner which was thought best adapted to the occasion, or which was rendered necessary by circumstances, seemed to require a systematic index, in which the nomenclature should be corrected, and the species arranged agreeably to my present views. This Synopsis, then, will afford a methodical catalogue of all the species hitherto discovered in the vast regions, extending from the northern confines of Mexico to the Polar Seas, and which have been described, and, with few exceptions, depicted in the works above named. Another important object has been to present an arrangement of these birds, so characterized, that a person desirous of studying them, might, without much difficulty, be enabled to discover their names, and trace some of the most important features in their organization.

The species are disposed into genera and families; and, although the location of the groups is not such as, in all respects, to satisfy me, the arrangement will, I trust, be found in some degree useful. It will be seen that, although I have adopted many of the modern groups, I have not sectioned our birds on so minutely divided a scale as that employed by some recent writers. Besides the characters of the Families, Genera, and Species, which are given with considerable detail, I have presented a short account of the Geographical Distribution of the species, and references to the principal authors by whom they have been described. I am confident that these notices will suffice to enable the student to determine with certainty any species that may come under his consideration, and that the information respecting its habits, which he will find in the works referred to, will afford him at least sufficient knowledge to form a basis for the more extended observation which he may contemplate. To the name of the genus I have appended that of the author by whom it has been instituted; and with the specific names I have dealt in the same manner, giving as authorities the individuals who first employed them, although they may have referred them to different genera. It is probable that many errors have been made in this department; but I shall be happy to see them corrected, as my wish is to do justice to all.

On this occasion I have again to acknowledge the benefit derived from the aid of my friend Mr Macgillivray, whose general knowledge of ornithology, and perfect candour, have rendered his advice peculiarly valuable.

### GENUS IV. HALIAETUS, Savigny. SEA-EAGLE

Bill rather short, very deep, compressed; upper mandible with the dorsal outline nearly straight at the base, beyond the cere decurved, the sides sloping, the edges nearly straight, with a slight obtuse process, and a shallow sinus close to the strong trigonal tip; lower mandible, with the dorsal outline slightly convex, the tip obliquely truncate.

> Bird of Washington, Falco Washingtonii, Aud. Orn. Biog. v. i. p. 58.

#### 14. 2. Haliaetus leucocephalus, Linn. White-headed Sea-Eagle. – Bald Eagle

> Plate XXXI. Adult Male. Plate CXXVI. Young.

Male. Tarsus with a few scutella; toes terminally scutellate. Male with the bill, cere, iris, and feet yellow; the head, the neck for half its length, the rump, upper and lower tail-coverts, and tail white; the rest of the plumage chocolate-brown, the terminal margins of all the feathers pale greyish-brown. Female similar. Young with the bill brownish-black, iris dark brown, feet yellow; the general colour of the plumage very dark chocolate, uniform, the feathers without edgings, all white at the base, that colour appearing more or less on the hind part, and more especially on the fore part and sides of the neck, and on the sides of the body and lower wing-coverts; quills and tail-feathers brownish-black, tinged with grey toward the base; the latter with the greater part of the inner webs, and a portion of the outer brownish-white, freckled with dusky. In more advanced stages the colours of the plumage vary considerably in different individuals. The general tint continues brown for several years, a variable and often a large proportion of white, or brownish-white, appearing on the neck, the lower part of the body, the sides, and under the wings, the tail meanwhile gradually becoming white in freckled patches, some have a large patch of brownish-white across the breast. When the feathers are new, they are of a glossy deep brown, but when old and worn they present a bleached appearance, and the upper parts are often patched with pale brown or brownish-white. On account of these circumstances, individuals of different ages, and shot at different periods of the year, differ so much from each other in appearance, that one might, without a very extended comparison, conceive that in a collection of specimens, there might be several species. The bill remains dark until the head and tail become white; the anterior tarsal scutella differ from none to six, the posterior from nine to twelve; those on the hind toe are four, on the middle toe from nine to thirteen.

Male, 34, 84.

Throughout North America. Resident in the south and west.

### GENUS VII. ICTINIA, Vieillot. ICTINIA

Bill very short, wide at the base, much compressed toward the end; upper mandible with the dorsal line decurved in its whole length, the sides slightly convex, the tip narrow and acute, the edges with an obtuse lobe; lower mandible with the angle very wide, the dorsal line ascending and convex, the tip rather broad and obliquely truncate. Nostrils round, lateral, with a central papilla. Head rather large, roundish, broad, flattened; neck short, body compact. Legs rather short; tarsus stout, covered anteriorly with scutella; toes scutellate above, scabrous beneath, with pointed papillæ; claws rather long, curved, acuminate, flattened beneath. Plumage rather compact. Wings very long, the third quill longest. Tail long, emarginate.

This genus is easily distinguished from Elanus; the tarsi and toes being scutellate in this, and scaly in that; and the festoon on the upper mandible is much more prominent in Ictinia, while the nostrils, instead of being elliptical, are round, as in the Falcons.

Adult male with the cere greenish-yellow, the feet pale orange, the upper parts light bluish-grey, each feather with a black central line; lower parts reddish or yellowish white, the breast and sides with large oblong brown spots; tibial feathers light red, streaked with blackish-brown.

Feathers margining the operculum with the shaft and webs undeveloped. Bill pale greyish-yellow; claws and scales brownish-yellow.

Male with the upper parts bluish ash-grey, streaked with black; crown, rump, upper part of throat, and a patch on the sides of the body, rich yellow; first row of small coverts largely tipped, and secondary coverts broadly margined and tipped with white, which thus forms a conspicuous patch on the wing; quills and tail brownish-black, narrowly margined with greyish-white; a patch of white on the inner webs of all the tail-feathers, but on the central reduced to a mere edging; a small white spot on each of the eyelids; loral space and cheek black; lower part of neck anteriorly, fore part of breast, and sides, variegated with black and white or ash-grey, the latter colours margining the feathers; the rest of the lower parts white.
