Yellow-bellied Greenbul
Chlorocichla flaviventris
A large, burly greenbul with greenish upperparts and yellowish underparts. It has a distinctive red-brown eye with a diagnostic broken white eye-ring. A small shaggy crest and yellowish underwings further differentiate it. Pairs or small groups skulk in thickets and forest edge, where they forage on fruits and insects and are often first detected by their nagging nasal “yeehn-yeehn-yeehn” calls and various chattering. The similar Joyful Greenbul differs from Yellow-bellied Greenbul by having olivaceous rather than yellowish underparts and by lacking the white eye-ring.
分类信息
The yellow-bellied greenbul was originally described in the genus Trichophorus (a synonym for Criniger) and then re-classified within Chlorocichla. Alternate names for the yellow-bellied greenbul include the African yellow-bellied bulbul, yellow-bellied bulbul, yellow-breasted bulbul, yellow-breasted greenbul and yellow-necked greenbul. The latter name is also used as an alternate name by Falkenstein's greenbul. The name 'yellow-bellied bulbul' should not be confused with the species of the same name, Alophoixus phaeocephalus.<p>Three subspecies of the yellow-bellied greenbul are recognized:

Sahul Sunbird
Cinnyris frenatus
Tiny and active sunbird of forest edges, parks, and gardens; ranges from Sulawesi east to the northern Moluccas, New Guinea, and northeastern Australia. Both sexes have a plain olive back, a yellow belly, and white tail edges that are flared out in flight. The male flashes an iridescent blue throat while the female has a yellow throat and eyebrow. In parts of range, female Sahul may be confused with female Black Sunbird; note that species’ unmarked gray head and shorter, less curved bill. Gives a buzzy, twittering song, as well as a rising “dwee”, a familiar sound even in cities. Formerly grouped with other, closely related species under “Olive-backed Sunbird.”
Pacific Reef-Heron
Egretta sacra
A small heron that hugs rocky coastlines. Light-morph individuals are usually white all over, though some may show patches of gray. Dark-morph individuals are entirely dark gray. Both morphs have a yellowish green bill and legs. Light morph adults are distinguished from egrets in the area by their distinct short-legged appearance and noticeably thicker bill.
Red-throated Crag-Martin
Ptyonoprogne rufigula
A subtly colored member of the swallow family. Dark brown on the back with paler underparts. The forked tail has white spots, though these are not always easy to see. The “red throat” amounts to a slight pinkish tinge. Nests in canyons, escarpments, gorges, and on human structures. Often seen in pairs or small groups. At a distance, can be confused with “Riparia” martins; look for Pale Crag-Martin’s white tail patches. Separation from Southern Crag-Martin may be tricky, but there is little overlap in range.
