Іктерія Icteria virens

Strange, long-tailed tanager-like bird with thick bill. Once thought to be a warbler, but now considered unique in its own family. Bright yellow throat and breast, contrasting white spectacles, and dull olive-green upperparts. Known for its skulking habits. Often difficult to see in dense thickets, shrubby areas, and field edges. In breeding season, however, males can sit on conspicuous perches to sing and even perform a flight display. Fairly widespread but typically uncommon across much of the U.S. and Mexico, wintering to Costa Rica. Song is variable series of slow whistles, hoots, and chatters. Feeds mainly on insects; also fruit in winter.
