分布与栖息地
The status of the species is evaluated as Least Concern. It is most commonly spotted on the Island Borneo, but can be found in Brunei, Indonesia, Malaysia, and the Philippines. It is also an introduced species in Natuna, Banggi, Cagayan and Sulu Islands. While the population size of the species is unknown, the population growth is stable, and virtually unthreatened. It is found in subtropical/ tropical lowland shrubland, forest and grassland habitat. Its habitat can vary widely, with sightings being recorded in the foothills of the island Borneo, grasslands, and agricultural fields such as rice paddy fields. They also tend to reside along riverbanks, reed-beds, secondary scrub and cultivated areas, from sea-level all the way up to 500 meters above ground. They are not migrants, and do not venture outside of their habitat during seasonal changes like many other species of birds.

Puff-throated Bulbul
Alophoixus pallidus
A large crested bulbul of tropical forests, usually found in the canopy foraging on berries. Body is a light yellow-green, while the wings, tail, and crown are brown. “Puff” of the white throat is slight and not an obvious feature. In the northwestern part of its range, it overlaps with the similar White-throated Bulbul, which has a more scraggly crest, more extensive white on the throat and face, and olive-green wings. Chatters with explosively harsh and barking quality; groups can be very loud and cacophonous.
Orange-fronted Barbet
Capito squamatus
Chunky black and white bird with a stout bill. Ranges in lowland and foothill rainforest west of the Andes in Ecuador and far southwestern Colombia. Note orange forehead and large white spots on the lower back. Male has white underparts with streaked flanks; female has black throat and breast, and white scaling on the back. Male can be distinguished from Five-colored Barbet by white underparts, crown, and nape. Typically stays high in the canopy, where it joins mixed-species flocks of tanagers and other small birds.

Long-tailed, dark songbird. Adults glossy blackish with strong metallic green-blue sheen above in good light, bright red eye. Immatures dark above, pale with short, dark streaks below.
