Rock Pratincole Small, dark, short-legged pratincole. In flight, shows a white rump and white stripes under the wings. Found mainly on rocks in fast-flowing rivers. Locally will also use sandbars in rivers and rocky islands in lakes. The call is a high-pitched and quickly repeated “kek.” Separated from other pratincoles by its combination of small size, dark coloration, and stripes under the wings. Link:

Lynes's Cisticola Medium-sized, streak-backed cisticola of middle-elevation uplands. Found in grassland and savanna on rocky slopes with a mix of bushes, grass, and often aloes. Generally inconspicuous; seen singly or in pairs. Vocalizations include a short, explosive, accelerating trill, and rising wails. Similar to Rattling Cisticola, but has more rufous in the face and a longer tail. As with all cisticolas, habitat and voice are important cues in identification. Link:

Ochre-faced Tody-Flycatcher Tiny flycatcher of dense vine-tangled, woody habitats including forest edges and second growth where it is easily overlooked. Distinctive plumage with a gray crown and a cinnamon face wrapping around a darker ear patch. It is olive above and paler below with two yellowish wing bars. The song is a low and sharp “trrrp” easily mistaken for a frog or an insect. Link:

Long-tailed Sibia Truly long-tailed, even for a sibia, this bird appears rather dainty and small-headed in comparison with most of its relatives. Gray overall, darker on the wings and tail. Mostly lacks the contrasting patterns of other sibias, with only a small white patch near the wingtip. Forages in flocks in open hill forests, edges, and adjacent scrubby second growth. Despite striking appearance, often heard before it’s seen: listen for its loud chittering rattle. Link:

Maroon-belted Chat-Tyrant Small flycatcher found near streams in Andean cloud forest. Plumage is mostly gray with a chestnut breast patch and bold white eyebrows that really stand out in the dark forest. Most common vocalization is a drawn out, high pitched “peeeeeer” that can be heard over the sound of rushing water. When agitated, also gives a raucous series of “pee-didit” calls. Formerly lumped with Chestnut-bellied Chat-Tyrant. Link:

Common Raven Large, glossy-black bird with a wedge-shaped tail. Larger than a crow with a longer, thicker bill. Distinctive shape in flight, with rather long, swept-back wings and long tail. Note smoother, steadier wingbeats compared with faster, choppier wingbeats of crows. Extensive range throughout the Northern Hemisphere. Found in a wide variety of habitats, including desert, coniferous forest, coastlines, sagebrush, tundra, and grasslands. Often solitary or in pairs, but can gather in small groups. Typical call is a loud, guttural croak, but makes an astonishing variety of other strange noises. Compare with Chihuahuan Raven in the southwestern U.S. and Mexico, and with various large, all-dark crows and ravens in Europe and Asia. Link:

Straneck's Tyrannulet Small flycatcher with a gray head, an olive-brown back, a whitish throat, and a yellow belly. Note the white eyebrow and broken eye-ring. Occurs in woodland and scrub; migrates to the northeast during the austral winter. The song is a single note followed by a trill: “twie tirrrrrrrrrrrrrrrrrr.” The similar White-crested Tyrannulet has a different song and is also slightly larger, with a white crown patch that is often concealed.

Masked Apalis A small, slender warbler with greenish upperparts and reddish eyes; gray crown and cheeks are separated from the black throat by a striking white moustache. Juvenile has a green crown and a yellow throat. Locally common at scattered locations in lowland forest below 1500 meters of elevation, preferring the lower strata of primary and secondary forest and scrub in clearings. Pairs give a continuous buzzy “dree-lip, dreep-lip, dree-lip” and a dry “strik-strik-strik.” Masked Apalis looks similar to some montane forest apalises, but Black-throated Apalis has a striking yellow-orange belly, and Black-faced Apalis, an Albertine Rift endemic, has a black crown and the moustachial streak reduced to a neck spot.
