Imperial Snipe
Gallinago imperialis
Hulking snipe of high-elevation elfin forest in the Andes. Large with a thick, drooping bill. Upperparts are black with bold cinnamon scaling; underparts are buff with black scaling, becoming paler on belly. It is larger, bulkier, and more brightly-colored than other high-Andean snipe. Shy and rarely seen; most likely encountered in dim, misty conditions when it may venture out onto a quiet trail. At display sites, birds fly overhead giving low, grating calls followed by a mechanical humming sound.
识别特征
This 29–31 cm (11–12 in) long snipe has a stocky body and relatively short legs for a wader. Its adult plumage is dark rufous brown except for the lower belly and undertail, which are white with heavy brown barring. The grey bill is long, straight and fairly robust, and the legs and feet are grey. The sexes are similar. The juvenile plumage is unknown, but in most snipes species, young birds differ from adults only in showing pale fringes on the wing coverts.<p>In flight, the imperial snipe looks heavy, broad-winged and short-tailed, and the banded belly contrasts with the dark breast and underwing. It has a shatteringly loud raucous song in its display flight, starting with single notes and moving on to double or triple notes.<p>Compared with other snipes with an overlapping range, the imperial snipe is obviously larger than the Magellan snipe, which has clear pale stripes on its back and lacks barring on the lower belly. The race which occurs in the Andes, Gallinago paraguaiae andina also has yellow legs.<p>The Andean snipe, Gallinago jamesoni, is similar in build to the imperial snipe, but is paler on the throat and underwings, and has a less contrasted lower belly.

行为
The imperial snipe occurs around the tree-line at 2,745–3,700 m (9,006–12,139 ft) altitude in mosaic habitats consisting of a mixture of bogs, mossy areas, moist elfin forest, tree-ferns and tall grass. Little is known about its habits and it is mostly observed when displaying.<p>The dawn and dusk aerial display involves flying high in circles performing the extremely loud song. This is followed by a dive during which the bird makes a drumming sound caused by the vibrations of its modified outer tail feathers.<p>The imperial snipe's diet is unknown, but other snipe species forage for insects and worms by probing with their long bills.

White-cheeked Antbird
Gymnopithys leucaspis
Distinctive antbird with pale blue eyering and snowy white underparts and rusty upperparts. Black eyebrow and cheek extends through neck sides and down flanks. Occurs in lowland rainforest east of the Andes; no range overlap with similar Bicolored Antbird. Most often seen in the vicinity of army ant swarms, perched on vertical branches or vines close to the ground. Several individuals may gather at a large ant swarm. Listen for harsh descending “churr” calls that might be a clue that there’s an ant swarm nearby.
Ashy Flycatcher
Fraseria caerulescens
A slim, cool-gray flycatcher with an upright posture, a white eye-ring broken by a dark stripe through the eye, and a short pale eyebrow. Individuals, pairs, and small groups prefer forest edge, dense woodland, and plantations, where they may join mixed-species flocks foraging in the mid-canopy. The species makes sallying flights to catch insects and small vertebrates, returning to a regular perch. The Ashy Flycatcher lacks the white outer tail feathers and horizontal posture of the otherwise similar Gray-Tit Flycatcher.
Oxapampa Antpitta
Grallaria centralis
Medium-sized antpitta described to science in 2020. It inhabits high elevation cloud forest along the east slope of the Andes in central Peru. Plumage is mostly chestnut brown with a pale patch on the belly. It does not show a distinct eyering or any gray in the crown, which helps to separate it from similar antpittas in the region. Voice is also very useful; songs include a single whistle repeated every four to five seconds as well as a quick, descending series. Usually stays low inside tangles where it is hard to see.
