Chestnut-bellied Chat-Tyrant

Long-tailed blackbird, very similar to Great-tailed Grackle but smaller. Male is darker black with less obvious glossiness (but still some, usually greenish); female is very similar to female Great-tailed but paler below. Extremely limited range in the vicinity of Lake Nicaragua and Lake Managua, where small flocks can be found in open grasslands and wetlands.

Widespread and fairly common in northern South America. This medium-sized woodcreeper is found in open wooded habitats, scrub, and riparian forest. The well-named woodcreeper has a very straight bill that can even look slightly upturned unlike most other woodcreepers. Also note the bill’s pale color. Otherwise, mostly dark brown with fine streaking on the head and breast, but note the unstreaked back. Very similar to Zimmer’s Woodcreeper, but listen for Straight-billed’s slightly slower song that typically goes up in pitch at the end. Striped Woodcreeper has more streaking on the back and a slightly decurved bill. Usually seen singly or in pairs working up tree trunks and branches, usually at lower to middle levels in forest. Sometimes follows mixed-species flocks.

Medium-sized olive green bird with a small head, massive eyes, and a short stocky bill. Olive-green apart from brownish wings and tail. Very secretive; found in the understory and middle levels of humid forests and second growth. The song is a loud double whistle.
