Grauer's Warbler
Graueria vittata
Taxonomically unusual though not very boldly marked warbler. In poor light, or at a distance, looks dingy overall. A good look reveals a brown-olive back, and underparts that are heavily marked with fine barring. Found in thick understory tangles in montane forest of the Albertine Rift. Usually detected by its odd voice: a high, short, rising trill which sounds more like an insect than a bird. Most likely to be confused with Green-backed Camaroptera, but is larger, has a dark rather than red eye, and has fine barring below.

Cinereous Bunting
Emberiza cineracea
Similar to Ortolan and Cretzschmar's Buntings. Males are faintly-streaked with a yellow-green head. Some populations have a yellow belly while others have a gray-white belly. Females and young lack bright yellow tones and are faintly streaked on the throat and breast. Belly whitish, not orange or buff like Ortolan and Cretzschmar’s Bunting. Breeds on open rocky mountain slopes with scattered bushes. During migration found in a varity of open habitats. Flight call is similar to that of Cretzschmar's Bunting, a sharp "Tzip."
Tschudi's Nightjar
Quechuavis decussata
Fairly common but nocturnal bird of lowland desert with scattered low bushes and agricultural areas with hedges and brush. Sleeps during the day on the ground or on a low shady perch; when flushed flies with quick stiff wingbeats and short glides. Note the broad rounded wings and snappy flight style, unlike pointed wings and erratic flight of Lesser Nighthawk, which occurs in the same areas. At night hunts from ground and low perches. Like all nightjars, may be located at night by brilliant amber eyeshine reflected in light beams.
Middle American Screech-Owl
Megascops guatemalae
Small, cryptically patterned, yellow-eyed owl of tropical lowland forest from Mexico to Panama. Tends to stay well hidden in the understory. Cannot be identified readily by sight, but it is the only screech-owl throughout most of its range and within its habitat. Song is a purring trill that can easily be mistaken for the purring of a toad or insect. Plumage varies from grayish brown overall to reddish.
