Masked Laughingthrush

Secretive, rare medium-sized antshrike of the dense forests of the Cordillera Divisor of remote western Brazil and eastern Peru. Males are dark gray with a bluish tint to the back and upperparts, while females are bluish-gray above and brownish-orange below. Inhabits the lower levels of forests, where it is more often heard than seen; voice is a fast series of notes increasing in speed before finishing with a final higher note.

Dull medium-gray finch with oddly long pointed bill, usually with pinkish or yellowish lower mandible. Female browner than male, with brown wingbars, but bill shape still very distinctive. Found at high elevations, usually above 1500m, in brushy areas or scrubby forest. Almost always found around seeding bamboo.

Large vireo, nearly identical in plumage to Red-eyed Vireo but slightly duller and browner. Drab olive-greenish above and white below with gray cap, white eyebrow, and brown eye. Telltale black whisker mark often difficult to see, but is diagnostic. Hooked bill is rather long for a vireo. Primarily a Caribbean species; exact extent of wintering range in South America is poorly known. Limited range in U.S.; breeds in scrubby mangrove forests in Florida. Can be difficult to spot in dense foliage, but listen for song: repeated two- or three-parted chirping phrases that are vaguely reminiscent of a more musical House Sparrow.
