. Key to North American birds. Containing a concise account of every species of living and fossil bird at present known from the continent north of the Mexican and United States boundary, inclusive of Greenland and Lower California, with which are incorporated General ornithology: an outline of the structure and classification of birds; and Field ornithology, a manual of collecting, preparing, and preserving birds. Birds; Birds. 760 SYSTEMATIC SYNOPSIS. âLONGIPENNESâGAVI^. extending the whole length of the feather, very narrow at the base, widening as it runs toward the tip, within 1^ inches of which it occupies the whole web; the rest of the web white, sep- arated from the black by a straight distinct line of division. The second, third, fourth, and fifth primaries have the same general characteristics, but the white space rapidly grows nar- rower and shorter, and runs up further in the centre than along the edge of the web, so that for a little way from its end it has a border of blackish along its outer margin; other primaries wholly pearl-blue, their inner webs margined with white. Bill coral or orange-red, with a slightly lighter tip ; feet blackish, their soles dull yellowish. Winter plumage: BUI less brightly colored, its apex and tomia duU yellowish. Front white; crown variegated with black and white, the former color increasing on the occiput and nuchal crest, which latter, though shorter than in summer, is almost or quite unmixed with white. This black extends forward on the sides of the head to the eye, which it includes. (But frequently found breeding in this imperfect condition of the black cap, which is much more usual than the complete black.) Tail not pure white, but glossed over with the bluish of the mantle, which deepens toward the tips of the feathers into dusky-plumbeous; also considerably less forked, the lateral feathers having little or nothing of a iilamentous character. Young-of-the-year in August: Bill con- siderably smaller and shorter
