Plumbeous Black-Tyrant
Knipolegus cabanisi
Medium-sized flycatcher of Andean slopes; rare in southern Peru, more common in Bolivia and northern Argentina. Male is separated from White-winged Black-Tyrant by grayer, less glossy plumage and from Cinereous Tyrant by darker belly. Female is told from those species by her dark (not pale) throat. Inhabits humid forest, often near rivers and streams. Perches on a bare branch or snag and sallies out after insects.

Rufous-bellied Heron
Ardeola rufiventris
Small, dark, chunky heron. There are rufous patches on the wing and belly; this can be hard to see when perched but is conspicuous in flight. Found in thickly vegetated wetlands, ranging from flooded grasslands to swamps. Usually solitary. Fairly shy but will sometimes stand in the open. Shares dark coloration with Black Heron, but has chestnut patches, all-yellow legs, and a yellow base to the bill.

Green Cochoa
Cochoa viridis
A gorgeously colored but highly elusive and uncommon bird found in extensive hill forests, particularly in areas with well-shaded ravines, gullies, and streams. Slow-moving and restricted to the canopy, where it blends in with the foliage. If seen, the green body is most obvious, followed by the black and silvery-blue bands on the wing. A better look would reveal a sky-blue head with a thin black eye-stripe and a pale blue tail. Listen for its song, a high, thin, even-sounding whistle, often given repeatedly but difficult to pin down.

Chapin's Flycatcher
Fraseria lendu
An extremely drab flycatcher that is gray-brown on the back and slightly paler below. With a good view, the short pale line above the bill is visible. A scarce and localized species of humid forest at middle elevations. Similar to African Dusky Flycatcher, but slightly larger and completely unstreaked on the underparts. Separated from other flycatchers by its plainness. The call is a short, spitting trill and the song is a long series of whistles, squeaks, and trills, given at high speed.
