White-throated Bulbul
Alophoixus flaveolus
Large bulbul with a wispy, upright crest. Rich brown above with a gray face and bright yellow belly. White of the throat usually not visible. Loud and gregarious, moving through the lower and middle levels of foothill forests, constantly giving loud, nasal, somewhat babbler-like calls. Puff-throated Bulbul is very similar, but range overlap is minimal; in Puff-throated, look out for a much whiter, prominent throat patch, darker underparts, and a darker brown cast to the plumage overall.
分类信息
The white-throated bulbul was originally described in the genus Trichophorus (a synonym for Criniger) until moved to the genus Alophoixus in 2009. Alternate names for the white-throated bulbul include the ashy-fronted bearded bulbul, ashy-fronted bulbul, white-throated bearded bulbul, and yellow-bellied bulbul. The alternate names 'ashy-fronted bulbul' and 'yellow-bellied bulbul' should not be confused with species of the same name (Pycnonotus cinereifrons and Alophoixus phaeocephalus respectively). The common name 'white-throated bulbul' is also used as an alternate name for each of the white-throated greenbul, eastern bearded greenbul, puff-throated bulbul and yellow-bellied bulbul. The alternate name 'white-throated bearded bulbul' is also used as an alternate name for the eastern bearded greenbul.<p>Two subspecies are recognized:

Red-headed Flameback
Chrysocolaptes erythrocephalus
A rare large woodpecker of forest and edge, where at least some large trees remain, on Palawan and neighboring islands. Green on the back and wings, with dark underparts and neck heavily marked with a cream color. Crown slopes to an angular crest above a large black ear spot. Head is bright red in males and red with orange spots on the crown in females. Similar to Spot-throated Flameback, but Red-headed has a pale yellow bill and lacks the black-and-white stripes on the head. Voice includes a loud, metallic, stuttering staccato trill and loud nasal squeaking.

Green Oropendola
Psarocolius viridis
Large, stocky bird. Green-and-chestnut plumage can look mostly black under some conditions and at a distance. Note size, yellow tail, and deep, rowing wingbeats. Reliably distinguished from other green-plumaged oropendolas by pale green-and-red bill. Found in rainforest canopy and edges as well as along rivers, in villages, and in savanna woodlands. Groups move noisily through the forest canopy in search of fruit and flowers. Large flocks are sometimes seen commuting between roosting and feeding areas. Distinctive song of male can be heard at a great distance.

Thick-billed Raven
Corvus crassirostris
A huge raven with a massive, bulging bill. There is a white patch on the back of the head and another at the tip of the dark bill. Found from middle to high elevations in a variety of habitats, including grassland, woodland, moorland, rocky areas, towns, and cities. Somewhat like Fan-tailed Raven, but much larger, with a white patch on the head. Large enough to be confused with raptors, but more uniformly black than any raptor. The call is a rattling “g-r-r-r-r-r,” lower and rougher than typical crow and raven vocalizations.
