Olivaceous Elaenia

A drab-colored and inconspicuous species typically found from the middle level to the canopy in woodlands, where it mostly feeds on fruits. This species can be distinguished from similarly shaped and colored Pearly-eyed Thrasher by its short dark bill and barred, not streaked, underparts. Song is a deliberate series of high-pitched squeaks and lower-pitched whistles. Most common call is a high, thin whistle.

Rare parrot, usually associated with Araucaria forests but can be found in other forest types. The body is mostly green with a small red patch on the forehead (just between the eyes), wings, and at the base of the outer tail feathers. Has a prominent purple scaly breast, which looks very puffy when the feathers are erected. Pale yellow terminal band to the tail and blue flight feathers also good field-marks.

Small antwren of understory and midstory of lowland rainforest. Males are dark gray with white wing bars and an extensive black throat patch; females are more geographically variable, but are generally reddish brown above and pale tan below north of the Amazon River, and grayish brown above, light buffy tan below south of the Amazon. Males similar to Ihering’s Antwren, which has a more extensive black throat patch and different voice, and Gray Antwren, which has a smaller black throat patch, or no black on throat at all. Females particularly similar to Gray Antwren south of the Amazon, but usually more evenly-colored; distinguished from female Ihering’s Antwren by lack of wing bars. One of the most common members of mixed species flocks, where can be easily detected by nasal “ee-eww” whines.
