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.”
识别特征
The Sahul sunbird is 10–11.4 cm (3.9–4.5 in) in length. The male weighs 6.7–11.9 g (0.24–0.42 oz), the female 6–10 g (0.21–0.35 oz). The species is sexual dimorphic. The male of the nominate subspecies is olive above, the remiges are black with green edging and the black tail has a white tip. The throat, side of neck and breast are blue-black iridescent. It has a yellow supercilium and a yellow moustachial stripe. The underparts are yellow. The iris is dark brown and the legs are black. The female lacks the iridescent throat patch.
分类信息
The Sahul sunbird was formally described in 1843 by the German naturalist Salomon Müller based on a specimen collected on the west coast of New Guinea. He coined the binomial name Nectarinia frenata. The specific epithet frenatus is Latin meaning "bridled". The species was subsequently moved to the genus Cinnyris that had been introduced in 1816 by the French naturalist Georges Cuvier. The Sahul sunbird was formerly considered as a subspecies of the olive-backed sunbird (now the garden sunbird (Cinnyris jugularis) but is now treated as a separate species based on the differences in plumage and the mitochondrial DNA sequence.<p>Four subspecies are recognised:

分布与栖息地
The Sahul sunbird is a resident species from Sulawesi and the Maluku Islands to New Guinea, the Aru Islands, the Bismarck Archipelago, northern Solomon Islands and northeastern Australia. It is found in various habitats including mangroves, forest edge, open scrub as well as parks and gardens.
行为
The elongated hanging nest is 30–60 cm (12–24 in) in length and has a hooded side entrance. It is usually placed between 0.5 and 1.5 m (1 ft 8 in and 4 ft 11 in) above the ground but can occasionally be as high as 10 m (33 ft). It is constructed by the female using grass, bark, moss, lichens, leaf fragments, vegetable fibres and spider webs. The clutch of 1–3 eggs is incubated by the female. The eggs hatch after 11–16 days and the young are then fed by both parents. The chicks fledge after 13–16 days. Normally several broods are raised each year.<p>It forages either singly or in small groups. The diet consists of small insects, spiders, nectar and small fruit.

Orange-crowned Euphonia
Euphonia saturata
Small finchlike bird, compact and short tailed with a stout bill. Male has notably orange-tinged underparts and dark upperparts with a purplish sheen. The orange-yellow crown is extensive (not restricted to the forehead like many other euphonias). Also note the underside of the tail, which is entirely dark. Females are plain yellowish-olive overall and difficult to separate from other euphonias, especially Thick-billed, but usually seen in pairs or small groups with males. Frequents woodlands, edges, and clearings in lowlands and foothills, often in fairly dry regions. Can be found in mixed-feeding flocks with other species such as warblers and tanagers.
Pacific Swift
Apus pacificus
A large dark swift with origami-like angularity in flight profile. Black overall with a slightly paler throat and a bright white rump patch. Long forked tail is prominent in flight and is often opened while the bird is banking. Migrates in enormous flocks, which give sharp trilling calls in flight. The only large “fork-tailed swift” in its range, but compare with Cook's, Blyth's, and Salim Ali's Swifts where ranges overlap.
Mussau Flycatcher
Myiagra hebetior
Male is entirely glossy black with a slightly erect crest. Female red on the back and pale whitish buff below, with a bicolored head: pale throat and head black to below the eye. On New Britain, female is dusky gray below and on the throat. Prefers primary forest and undisturbed second growth. Song is a series of loud, piercing whistles. Call is a buzzing nasal churr.
