Key to North American birds [microform] : 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. Birds; Ornithology; Oiseaux; Ornithologie. 760 SYSTEM A TIC SYNOPSIS. — LONGIl'ENNES — GA VIJE. extending the whole length of the feather, very narrow at the base, widening as it runs toward the tip, witliin 1^ inches of which it occupies the whole web; the rest of the web white, sep- arated from tlie black by a straight distinct line of division. The second, third, fourth, and iiftli primaries have the same general diaracteristics, but the wliite space rapidly grows nar- ntwer and shorter, and runs up further in tlie centre than along the edge of the web, so that fur a little way from its end it lias a Ixu'der of hlackisli along its outer margin; other primaries wholly pearl-blue, tlieir inner webs margined with white. IJill coral or orange-red, with a slightly liglit(T tip; feet blackish, their soles dull yellowish. Winter plumage: Bill less brightly odorcd, its apex and toinia dull yellowish. Fvont white; cuiwn variegated with black ami white, the former color increasing on the occiput and nuchal crest, which latter, though shorter than in sununer, is almost or quite unmixed with white. This black extends forward on the sides of the head to the eye, which it includes. (Hut frecfuently found breeding in tliis imperfect condition of the black cap, which is much more usual than the complete black.) Tail not pure white, but over with tlie ;ili of the mantle, which deepens toward tlie tips of the feathers into dusky-plumbeous; also considerably less forked, tin; lateral feathers having little or nothing of a filamentous diaracter. Young-of-tlie-year in August: Bill con- siderably smaller and shorter tlian in the adult; its tip less acute, and its angles and ridges less sharply defined; mostly reddisli-yellow, but light yeUowis
