Philippine Swiftlet
Aerodramus mearnsi
Uncommon dark swiftlet. Endemic to a smattering of the Philippines islands, from Luzon to Mindanao to Palawan. Habitat can be helpful in identifying this confusing species; generally favors ridges and slopes in montane and submontane areas above 700-800 meters. Readily confused with significantly larger Ameline Swiftlet, but present species has a more squared-off-looking tail (fork is shallow and often unnoticeable), tends to fly lower and more erratically, and more often forms flocks. Combination of dark rump, unglossed dark back, and medium size separates this species from Gray-rumped Swiftlet, Pygmy Swiftlet, and Ridgetop Swiftlet. Frequently calls while in flight, giving a squeaky chattering twitter.

Chinese Gray Shrike
Lanius sphenocercus
A beautiful silvery shrike with gray upperparts, white underparts, a black mask, and white in the wings. The white patches in the black wings and tail are especially conspicuous in flight. Found in open areas with scattered or scrubby vegetation, frequenting agricultural fields in the winter; often sits on tall and exposed perches. Vocalizations include harsh rasping notes and more musical, liquid ones. Can be similar to the smaller Northern Shrike, but look out for Chinese’s gray rump, slender pale eyebrow, and more extensive mask. Also similar to Giant Shrike, but smaller, with a paler gray back and a white eyebrow.

Gray-crowned Flatbill
Tolmomyias poliocephalus
Small, stocky flycatcher with broad, flat bill. Occupies canopy and midstory of forest edges, gardens, and tall second growth in humid lowlands. Has gray crown, pale yellow underparts, and yellow edgings to wing feathers (but not wingbars). Very similar to a few other species of flycatchers, particularly Yellow-margined and Yellow-olive Flycatchers; best distinguishing features include its pale eye, lack of a yellow patch at the base of the primaries, and voice. Call is a loud, quickly rising whistle: “tuee?”, higher and cleaner than similar calls from species like Brownish Twistwing and Blue-backed Manakin, but not as high as the “twee-twee” of Purple-throated Euphonia.

Bates's Sunbird
Cinnyris batesi
A very small nondescript sunbird with a short orange-based bill that curves uniformly along its length; easily mistaken for females of other sunbirds. The only features on the olive upperparts are indistinct paler eyebrows and lines running under the eyes, and yellow edging to the wings. Although often hidden, the male has yellow or whitish (not red) tufts at the shoulders. Singles are local and inconspicuous at the edges of lowland and riverine forest, sometimes entering secondary growth; it joins mixed-flocks and is frequently attracted to epiphytes in mossy clumps. Calls a high-pitched “tseeep” and trills. Little Green and Fraser’s sunbirds are similar to Bates’s but brighter, with straighter bills and more distinct yellowish eye-rings; Ursula’s Sunbird has a long decurved bill and grayish face and underparts.
