Atlapetes melanopsis

Rare brushfinch with a highly restricted range in the eastern Andes of central Peru. It has an ornate head pattern with a partial black mask bordered by chestnut, black-and-white mustache stripes, and a white spot between the eye and the bill. The only similar species is Apurimac Brushfinch, which is found farther southeast and has a smaller mask and thinner black mustache. Black-spectacled inhabits scrubby areas at the forest edge. Song is a series of rich, wheezing notes.

Columba unicincta

Large, pale gray pigeon. There is red bare skin around the eye, a reddish wash on the breast, and a pale gray tail band that is conspicuous in flight. Found in rainforest and gallery forest, singly or in small groups. Often seen in flight or perched conspicuously on dead trees. The call is a long series of descending “huuuoooo” calls. Separated from other forest pigeons by overall pale coloration and bold tail band.

Tringa ochropus

Dark brown sandpiper with a snowy white belly; in flight looks black above with boldly contrasting white rump. Bobs tail when nervous, but not habitually like Common Sandpiper. Often climbs steeply when flushed and flies quickly with deep wingbeats, swooping around a little like a swallow. Breeds in clearings and marshes in wet forest and woodland; migrants occur in fresh and brackish wetland habitats, especially on muddy shores of lakes and small ponds. Mainly found as singles or small groups, not mixed with other species.
