Marbled Frogmouth
Podargus ocellatus
Large, nocturnal bird with very wide "frog-like" bill, an inhabitant of rainforest habitats. Compared to similar Tawny Frogmouth (often found in urban and suburban areas), Marbled has longer tail in proportion to its body, longer barred tufts above the bill, and a more blobby or marbled pattern on the underparts. Unusual call is a descending, turkey-like gobble, followed by a loud snap of the bill.
分类信息
There are five subspecies recognised; the nominate ocellatus is found in New Guinea and surrounding islands. Two subspecies are found on islands of Papua New Guinea; intermedius is found on Trobriand Islands and D'Entrecasteaux Islands, meeki is endemic to Tagula Island. Australia has two subspecies; marmoratus is found on Cape York Peninsula, plumiferus (known locally as the plumed frogmouth) is found in south-east Queensland.<p>Rigidipenna inexpectatus, endemic to four islands in the Solomon Islands, was formerly considered a subspecies. It was split into its own genus, Rigidipenna, in 2007.

分布与栖息地
The Conondale ranges in Queensland's Sunshine Coast is considered a stronghold for the plumed frogmouth; notable populations are within the Conondale National Park. The species is rare and is listed as vulnerable in Queensland and occurs in subtropical rainforest and vineforest at altitudes from 50–800 m. The species roosts in the canopy of and is considered cryptic and extremely hard to find or study. Current populations are threatened by land clearing, inappropriate fire regimes and timber harvesting with future impacts of climate change posing additional risks. There have been estimates of the current pairs in the Conondale ranges being around 800 pairs with the current range of the species is just under 2000 ha with some potential future habitat increase in population being created by regenerating rainforest previously logged. Its specialised habitat requirements being un-logged pristine forests, the species is considered extremely vulnerable due to significant habitat reduction. Future harvesting of native timber in the Conondale region also poses risk.

行为
P. ocellatus is a nocturnal ground feeder. During the day, it sleeps on a tree branch with its beak pointing upward, taking on the appearance of a tree branch. To cope with the heat and humidity of its tropical home, P. ocellatus has heart and respiration rates lower than is typical for birds of its size. During periods of hyperthermia, it will enact panting as a cooling mechanism, with more efficient cooling effect than is seen in other bird species performing the same action.<p>

White-winged Chough
Corcorax melanorhamphos
Large, black, crow-sized bird with decurved bill and deep red eye. In flight, white in primaries very evident. Struts around in family groups on the ground in open woodland areas around southeastern and eastern Australia. A variety of calls includes a plaintive, descending whistle.
Black-faced Munia
Lonchura molucca
A striking finch with a black hood, light brown collar, extensively barred white underside, and pale barred rump. Juveniles duller, brown above and buffy below, lacking bars. Singles to small groups inhabit open country in lowlands and foothills, including croplands, scrub, grassy areas, and woodland edge. Terrestrial, but perches in trees and bushes too. Adult differs from Scaly-breasted Munia in black hood and pale rump. Juvenile has a smaller bill than immature Five-colored Munia. Gives high-pitched, buzzy “krrit” calls, like a tiny tin horn.
Seychelles White-eye
Zosterops modestus
A small, sharp-billed warbler-like bird. Very dull olive-brown in coloration, with conspicuous white “spectacles.” Found locally in forest, woodland, and gardens on some of the granitic Seychelles islands. Usually found in hyperactive flocks. Vaguely similar to Seychelles Warbler, but smaller, shorter-tailed, and darker below, with bold white spectacles. Most common call is a “tew” note given singly or in a series. The song is a complex, varied sequence of high-pitched notes.
