Caspian Tit

Large antbird, mostly dark olive-brown with black-and-white bars on the chest. Look for the conspicuous white-crested forehead. Both sexes look similar. Found in the understory of humid forest, where it is an obligate ant-swarm follower. The song is a series of slow descending whistles.

Slender and drab songbird of open country. Brownish above with heavy streaking below. Distinguished from similar-looking (unrelated) buntings by thin bill and lanky appearance with long legs. Walks on the ground with jerky motions and frequently bobs tail. Breeds in tundra, while in winter and during migration, found in cultivation, moist grassland, and wetlands. Flocks are often heard as they pass overhead or flush from a barren field; listen for sharp, high-pitched call notes and look for flashing white outer tail feathers.

Small, active tanager with notably different male and female plumages. Male is steely blue overall with slightly darker wings. Look for sea-green throat and cheek, streaked upper breast, and contrasting black cap and nape. Female is mostly lime green with pale bluish head and breast; she has just a ghosting of the male’s black cap. Usually found in pairs, often following a mixed-species flock in the canopy. An Andean species, found in subtropical forest, edges, and gardens. Visits fruit feeders.
