Glaucous Tanager

This is a large woodcreeper with a hefty straight bill. Look for the combination of pale streaks on the head and breast and dark barring on the belly. Large range from Central America to northern Argentina, but usually uncommon. Occurs from lowlands up to around 2,000 m. Typically found in mature forest, singly or in pairs, sometimes following a mixed-species flock or ant swarm. Listen for a loud ringing trill that usually falls slightly in pitch, where each note sounds clipped.

Small, range-restricted antbird of northwestern Amazonia. Most often found in forests on sandy soil, less frequently in dense woodland growing in the transition between upland and flooded forests. Note brownish upperparts, darker wings and tail, and grayish underparts; the male has a darker throat. Distinctive song is a fast rising series of burry whistles, similar to Plain-throated Antwren’s song but faster and more even in pace.

A relatively thick-bodied, long-tailed warbler, prone to creeping like a mouse low in vegetation. Dark brown above. Chest and face paler orange-rusty with a dark eye-stripe. Belly darker than chest. Found in dense dark stands of bamboo, ferns, and forest undergrowth above 900 meters of elevation. Voice reported to be a two-noted whistled phrase, followed by a single higher-pitched note.
