Red-winged Laughingthrush
Trochalopteron formosum
Striking large laughingthrush of broadleaf hilly and montane forests in central-southern China and far northern Vietnam. Look for bright red wings and tail, pale silver-gray crown and cheek patches, and extensive dark throat and chest. Compare with orange crown, paler whitish cheeks, and less extensive dark throat of Red-tailed Laughingthrush, which overlaps marginally with this species in range, but tends not to occur in the same areas. Shy, often staying in dense bushes; forages in pairs or small flocks close to the ground. Gives a wavering whistle: “dooEEEEooo.”

White-browed Forest-Flycatcher
Fraseria cinerascens
An easily overlooked flycatcher of lowland forests near large waterways, lurking in the lower parts of the forest in shady areas or near cover. Distinctively dark gray above and pale scalloped gray below, with a bright white throat and a bright white spot in front of the eye. Distinguished from other flycatchers by its affinity for water combined with its bright white lores. Song consists of long, deliberate buzzy whistles rising and falling in pitch: “Dzhreee? Dzhreeerr. Dzhreeeer?”

Yellow-throated Nicator
Nicator vireo
A shy but loud bird of forests and forest edges that usually stays within cover. Shaped like a greenbul, but has a thicker, more robust bill. Shows grayish underparts, greenish upperparts, yellow spots on the tips of the flight feathers and upperwing coverts, a yellow throat, and yellow lores. Similar to the larger Western Nicator, but note Yellow-throated’s smaller size, yellow throat and lores, and distinctive song, which often betrays its presence: a sputtering series of notes that can be surprisingly resonant and loud, a “p-p-p-po-keer-ko-wheeeer-pop” and other variations. Call is a growling trill, “prrrrrr.”

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.
