分布与栖息地

It inhabits primary dipterocarp forest, typically on mountain slopes (although this may simply reflect a constraint enforced by forest loss), occasionally visiting isolated fruiting trees over 1 km from the nearest forest. It requires large trees for nesting. Whilst the species's diet mainly consists of fruit, small lizards and some insects may also be consumed.<p>IUCN has assessed this bird as critically endangered. In 2019 it was reported that only 27 mature individual hornbills are still believed to be alive in the wild. This makes it the most endangered hornbill and one of the most endangered animals in the entire world. It has gone extinct on the island of Jolo, due to hunting and the remaining populations in Tawi-Tawi are threatened by habitat destruction through logging and slash-and-burn farming.

Blue-throated Goldentail

Blue-throated Goldentail

Chlorestes eliciae

Uncommon and local, rather small hummingbird of humid forest edge, plantations, and woodlands in tropical lowlands and foothills. Perches and feeds mainly at middle to upper levels in shady understory and at edges. Note the bright red bill and greenish-gold tail (which often looks grayish). Male has violet gorget. Female has violet throat spotting, but often these areas look rather dull and grayish unless they catch the light.

Ruby-crowned Kinglet

Ruby-crowned Kinglet

Corthylio calendula

Tiny, hyperactive songbird with an uneven white eyering. Plain olive overall, with slightly brighter greenish edges on the wing and tail feathers. The namesake ruby crown is only present on males, and usually concealed. When agitated, it can be flared up into a bright expressive crest. Breeds in coniferous forests. In migration and winter, found in basically any wooded habitat, including deciduous forests, shrubby woodland, and field edges. Often forages quite low to the ground, sometimes joining mixed flocks of other songbirds. Energetic, moving quickly and flicking its wings. Listen for short, harsh call notes, usually doubled, and surprisingly loud song for such a small bird. Compare with Hutton’s Vireo, which is similar in plumage but has a thicker bill and forages more sluggishly.

Cinnamon-bellied Imperial-Pigeon

Cinnamon-bellied Imperial-Pigeon

Ducula basilica

A distinctive large pigeon with a pale pink head and neck, a deep cinnamon belly, dark greenish upperparts and tail, and a broad pale band at the tail tip. Singles to small groups inhabit forest and forest edge, including degraded forest and plantations. Perches high, but rarely in the open. Overlaps with Spectacled Imperial-Pigeon, but differs in its pink head, its lack of a bold eye-ring, its cinnamon belly, and its pale tail band. Gives a signature deep two-note growl, “ku-woooo,” with a curt, rising first note and a longer second note.
