Double-banded Pygmy-Tyrant
Lophotriccus vitiosus
Tiny flycatcher, more often heard than seen. In addition to tiny size, note elongated crown feathers (usually held flat) and plain underparts. Found in a variety of forest types, especially those on sandy soils. May be alone or in pairs; perches well inside dense vegetation, usually at lower levels but occasionally into subcanopy. Sits still and darts upward to foliage for insect prey. Song is a hard, buzzing trill, repeated over and over and with little geographic variation. Similar to Helmeted Pygmy-Tyrant and often found in the same habitat; best told by voice, and, if seen well, by clear pale underparts that lack olive mottling.

Sulu Hornbill
Anthracoceros montani
A large bird of lowland and montane forest on the Sulu Islands, although probably only remaining on Tawi-Tawi. Feeds particularly on fig trees. One of the rarest birds in the world. Entirely black except for a white tail. Has a long, thick black bill, a black casque, and black bare skin around the eye. Male has pale eyes and female has brown eyes and a smaller casque. Unmistakable. The only hornbill in its range. Voice is a nasal cackling.
Olive-headed Greenbul
Arizelocichla striifacies
Large chunky, olive-green greenbul. There is geographic variation in the color of the eye (pale or dark) and the amount of yellow on the underparts. Throughout the range, shows a dark cheek with diagnostic fine pale stripes, though a good look is required to see these. Found in humid foothill and montane forest. Often joins mixed flocks with other birds. The song is a chatty, up-and-down series of low “chowp” notes and higher nasal notes. Similar to mountain greenbuls, but always separated by the more distinct cheek striping.
Swinhoe's Rail
Coturnicops exquisitus
This sparrow-sized rail moves like a ghost through grassy meadows and wetlands. Prefers to run instead of fly, but white wing patches are unmistakable if seen. Flight is weak with dangling legs, drops into cover quickly. Belly is white with brown bars on the sides and upperparts are darker brown with fine white stripes. Voice is the only way to detect this species; its repertoire is varied, with grunts, squeals, and tapping notes.
