Jumbo-sized, long-tailed warbler with thick bill; almost a mix between a warbler and tanager. 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 sit on conspicuous perches to sing. Song is variable series of slow whistles, hoots, and chatters. Feeds mainly on insects; also fruit in winter.
