Dark-winged Miner
Geositta saxicolina
Plain bird found in treeless areas of the high Andes of central Peru. Plumage is sandy brown with a buffy tinge on the face and breast. The buff rump is usually only evident in flight. Distinguished from Common Miner by its unstreaked breast. Similar to some species of cinclodes, but does not have a white throat and lacks eyebrows. Feeds on the ground, and often perches up on rocks.

The dark-winged miner is a year-round resident throughout its range.<p>The dark-winged miner forages on the ground, singly, in pairs, and possibly in small family groups. Its diet has not been described but is known to include insects; it is assumed to also eat other arthropods and seeds.<p>Almost nothing is known about the dark-winged miner's breeding biology. Its nesting season includes December but is otherwise unknown. It is assumed to nest in a chamber at the end of a burrow in the ground like others of its genus.<p>The dark-winged miner's vocalizations are imperfectly known. One whose purpose is unknown is "a pretty, melodic cheecheechee-chi-chi-chi-chi". Its calls include "chips and very short raspy notes" and in flight it gives a "tirr tirr tirr".

Tuamotu Sandpiper
Prosobonia parvirostris
A small, very dark brown shorebird with a very short thin bill and a distinct white eyebrow. Upperparts spotted with buff, underside spotted or barred with brown. Legs yellow or grayish. In flight, looks very dark with very rounded wings. Prefers coastal shoreline and bare gravel of tiny atolls. Combination of odd proportions, very short thin bill, and white eyebrow should make this species unmistakable. Most common call is a nasal “kek,” but when excited gives a loud piping whistle and a series of rising and falling trills.
Green-tailed Emerald
Chlorostilbon alice
Small, compact, short-billed and short-tailed hummingbird with green tail. Male all glittering green; female green above and gray below with dark cheek, white eyeline, and white-tipped tail. Occurs in dry to humid forest borders in montane regions (no higher than 2500 m), usually in gardens and cultivated areas. Often perched alone near small flowers at mid-height. Very similar to other emeralds; distinguished from both male and female Blue-tailed Emerald by green tail; from Short-tailed Emerald by having wings and tail the same length when perched; and from male Narrow-tailed Emerald by uniform length tail feathers. Endemic to the Andes and Coastal Cordillera of Venezuela.
Lined Forest-Falcon
Micrastur gilvicollis
Fierce-looking raptor of lowland rainforest interior east of the Andes; also ranges up into the foothills in a few areas. Gray with dense barring from throat to breast and an orange face (yellow in younger birds). Similar to Barred Forest-Falcon but usually has a darker orange face and little or no barring on lower underparts. Stays inside forest and is heard far more often than seen. Call is two or three nasal honks, repeated every few seconds.
