Linaria flavirostris (Twite)

Synonyms: Acanthis flavirostris; Carduelis flavirostris (homotypic); Fringilla flavirostris (homotypic); Linota montium

Wikipedia Abstract

The twite (Linaria flavirostris) is a small brown passerine bird in the finch family Fringillidae. It is similar in size and shape to a linnet, at 13 to 13.5 centimetres (5.1 to 5.3 in) long. It lacks the red head patch and breast shown by the linnet and the redpolls. It is brown streaked with black above, and a pink rump. The underparts are buff to whitish, streaked with brown. The conical bill is yellow in winter and grey in summer. The call is a distinctive twit, from which its name derives, and the song contains fast trills and twitters. Twites can form large flocks outside the breeding season, sometimes mixed with other finches on coasts and salt marshes. They feed mainly on seeds.
