Grimwood's Longclaw

Thickset, short-winged, pot-bellied gull. Adult has dark gray back and wings, intense pink legs, and an especially large white “crescent” (white tertial edges) near the wingtips when perched. Breeding adult white-headed; nonbreeding birds have variably heavy brown streaking on the head and upper breast. Takes four years for immatures to progress from mostly brown to fully white and gray adult plumage; intermediate plumages are often mottled and messy. Often looks rather frosty by the first winter; starts to develop a gray back and whitish eye in its second year. Primarily an Asian species, found in coastal regions from Japan and South Korea to Russia. Regularly occurs in western Alaska, but very rare elsewhere in North America.

A tiny nondescript bird with a pale and bulky curved bill. Endemic to the Indian subcontinent where it can occur in any habitat that is not too dry, too wet, or too high. Shows a particular fondness for Singapore Cherry berries. Often only seen in flight making a fast “thik-thik” call that recalls Nilgiri or Plain Flowerpecker. Songs include a unique high-pitched trill. When not singing, a view of the bill is essential to identify the species in any region where either of Nilgiri or Plain flowerpecker is also present.

A nest parasite that lays its eggs in the nests of Bar-breasted Firefinch. Breeding males are glossy purplish-black with a pale brownish panel in the wings, while females and non-breeding males are brown and streaky on the back and pale below, with a bold facial pattern. The bill is white and the legs pinkish. Found in a wide variety of open habitats including open woodland, thickets, savanna, cultivated areas, and scrub. Breeding males can be identified with care by their vocalizations and purple gloss. Non-breeding males and females cannot be separated visually from other indigobirds. Imitates the vocalizations of its host firefinches: a low “chip” call and an up-and-down twittering song.
