Black-and-rufous Swallow
Hirundo nigrorufa
A small, gorgeous swallow with blue-black upperparts, rump, and face, and uniform rich rufous chin, throat and underparts. In flight the underwing coverts are rufous. The juvenile is duller than the adult. Singles or pairs are scarce in grassland and savanna, often associated with the edges of swamps, rivers and partially flooded areas. Similar Red-throated Swallow has a reddish rump and is less rufous below than the much more neatly-plumaged Black-and-Rufous Swallow; other similar swallows are larger with longer tails, red rumps and paler underwing coverts.

Cocoa Woodcreeper
Xiphorhynchus susurrans
Warm brown bird with buffy streaks on head and breast; hitches up tree trunks. Generally longer tailed and longer billed than a woodpecker. Very similar to many other species of woodcreepers. Focus on bill: long, fairly thick, and almost straight; generally pale grayish with fleshy tones, but darker on top edge. Listen for song, a long series of clear whistled notes fading slightly at the end. Found in wooded habitats, often in more open forest, edge, or second growth.

Visayan Babbler
Sterrhoptilus nigrocapitatus
A fairly small bird of lowland and foothill forest and edge; endemic to Samar, Leyte, and Bohol, though lumped with Calabarzon Babbler under “Black-crowned Babbler” by some taxonomies. Has a gray back and cheek with fine pale streaks, dark wings and tail with white outer tail feathers, white underparts, a pale rufous throat, and a black crown. Note the slender black bill. Often joins mixed-species flocks and sometimes hangs upside down while feeding. Somewhat similar to Green-backed Whistler, especially from below, but smaller, with a pale rufous throat and a black crown. Voice includes a medium-pitched “poo piuu!” with the second note downslurred.

Yellow-streaked Greenbul
Phyllastrephus flavostriatus
Slim, pale greenbul. The yellow streaks on the underparts are always hard to see. The crown color varies geographically: can be olive-green or gray. Found in moist forest, especially montane forest. The most distinctive attribute of this species is its behavior: creeping along midstory branches in almost woodpecker-like fashion, frequently flicking out one wing. Gives nasal calls and a descending series of more musical whistles. Easily confused with other greenbul species, but much paler overall than most greenbuls, and wing-flicking behavior is diagnostic.
