Black-browed Reed Warbler
Acrocephalus bistrigiceps
Dull brown reed warbler with a sharply marked head, found in a variety of wetland habitats with substantial vegetation cover. Namesake black brow line is not always apparent, but the thick and strikingly pale supercilium is distinctive in its clean-cut and squared-off appearance. Somewhat similar to the rarer Streaked Reed Warbler, but averages much darker and lacks the latter's black striping on the back and wings. Song is a scrambled set of chatters, chirps, and rattles, more musical and tuneful than Oriental Reed Warbler. Gives dry “chit,” often in series.

Apo Myna
Goodfellowia miranda
A fairly large, long-tailed bird from montane forest in localized areas of Mindanao. Plumage mainly glossy black with a white patch on the back. Bill, legs, and large area of bare skin around the eye are yellow. Note the tall wispy crest. Forages in pairs or small groups for insects or fruits, sometimes with other species, including Coleto. Unmistakable. Voice includes slurred metallic warbles and a sharp, falling “tsik!” Also makes audible wing beats in flight.
Brown-necked Raven
Corvus ruficollis
Large and black, almost as big as Common Raven. Its namesake brown neck is only visible at close range in specific lighting conditions. Bill is slightly thinner, tail shorter and less wedge-shaped, and the call is less deep and throaty compared to Common Raven. Found exclusively in arid zones where it breeds on cliffs, trees, and pylons. Moves around in pairs or small groups, but may congregate at abundant food sources in larger groups.
Tepui Elaenia
Elaenia olivina
Confusing flycatcher of montane forest. It has olive-gray upperparts, pale yellow underparts, white wingbars, and a small crest that is usually held flat. When crest is raised, it may show some white. Darker and yellower than other elaenias, and usually only elaenia in its habitat. Birds in worn plumage may not be identifiable with certainty. Its most common vocalizations, which include clear whistles and burry calls, are similar to those of other elaenias.
