Sooty Oystercatcher
Haematopus fuliginosus
Heavy-set shorebird with entirely black plumage and long, thick reddish bill. It has a distinctive fleshy red or yellow eye-ring and very thick pale-pink feet and legs. Exclusively coastal, where it can be found walking around on the edge of rocky headlands, on rock shelves, and along rocky beaches on small islands. Typically found in pairs or small groups. Its call is a loud slow whistled "chew", or when agitated a rapidly repeated "squeaky toy" call.

Measuring 42 to 52 cm (16.5 to 20.5 in) long with a bill length of 5–8 cm (2–3 in), the sooty oystercatcher has all black plumage, with pink-red legs and scarlet or orange-red bill and eyes. The heaviest of all oystercatchers, the sooty oystercatcher weighs up to 980 g (2.16 lb), averaging around 819 g (1.806 lb), with females larger and heavier in both subspecies. Males have shorter, thicker bills and females have longer, thinner bills. The 19% average difference in length is the most marked of any oystercatcher species. Immature birds have grey-brown legs, a bill tipped with brown, a browner cast to their plumage, and brown eyes. The bill, eyes and legs become red by the second year.
分类信息
John Gould described the sooty oystercatcher in 1845. Its species name is the Latin adjective fuliginosus, "sooty". Two subspecies are recognised, the nominate from the coastline of southern Australia and subspecies ophthalmicus from northern Australia. The southern subspecies is larger and heavier than the northern. The northern one, with a more yellowish eye ring, is found from the Kimberleys across the top of the country to Mackay in central Queensland. There is considerable overlap, as the southern subspecies has been found up to Cape York. Subspecies ophthalmicus has been thought distinctive enough to warrant species status and needs further investigation. Black redbill is a local name.

分布与栖息地
Preferring rocky shores, the sooty oystercatcher is endemic to Australia. There are an estimated 11,500 individuals, 4000 of the nominate race and 7500 of the northern race. It is common around the Tasmanian coastline and Bass Strait islands. However it is declared Rare in South Australia and Queensland, Near Threatened in Victoria and Endangered in New South Wales.

Salvadori's Pheasant
Lophura inornata
Chunky pheasant endemic to Sumatra’s highlands and foothills. Male is dark iridescent blue, while the female is warm brown with a dark tail. Both sexes have short tails, bright red patches of bare facial skin, and pale bills with a faint hook. Forages quietly on the forest floor, typically singly, sometimes in pairs. Generally fairly quiet; deep “bwoop” contact calls sometimes given, and males give a wing-whirring display that can be audible at close range.
Pacific Flatbill
Rhynchocyclus pacificus
Shy and inconspicuous flycatcher of lowland and foothill rainforest in western Colombia and northwestern Ecuador. Plumage is mostly olive with yellowish streaks on underparts, gray eyering, and brown patches in wings. Bill is very wide at the base, though this may not be evident when the bird is seen from the side. Similar to Fulvous-breasted Flatbill, but Pacific lacks tawny breast and is usually found at lower elevations. Also similar to Olivaceous Flatbill, but has brown (not yellow) in the wings. Typically found alone or in pairs at fairly low levels inside the forest, and sometimes joins mixed-species flocks.
Yellow-crowned Flowerpecker
Dicaeum anthonyi
A tiny bird of mossy montane forest and edge on Luzon. Male has glossy black upperparts, pale underparts (whiter on the throat), and the namesake yellow crown stripe. Female has olive upperparts. Similar to Bicolored Flowerpecker, but male Yellow-crowned has a bright crown patch and female has a more yellowish belly. Voice includes a high-pitched descending whistle and a sharp “tsik!” Treated by some taxonomies as subspecies of Flame-crowned Flowerpecker, which is endemic to Mindanao.
