Pink Robin
Petroica rodinogaster
Small, plump Australian robin. Male very dark gray above and on throat, with lovely pink breast and belly. Tail completely dark, unlike Rose Robin. Female brown above, paler below, sometimes tinged pinkish. Breeds in very wet dense rainforest gullies in Tasmania and Victoria, sometimes in other more open habitats in winter.
识别特征
The pink robin is 13.5 cm (5.5 in) long and displays sexual dimorphism – the males and females have plumage which differ markedly. The male has a dark blackish-grey head, throat, back, wings and tail, a pink breast and belly fading to white on the lower abdomen, and a white forehead. The female is dark grey-brown above, with two buff-coloured wing-bars and pinkish-tinged underparts. The bill and feet are black, and the eyes are dark brown.
分类信息
Described by Belgian naturalist Auguste Drapiez in 1819, the pink robin is a member of the Australasian robin family Petroicidae. Sibley and Ahlquist's DNA-DNA hybridisation studies placed this group in a Corvida parvorder comprising many tropical and Australian passerines, including pardalotes, fairy-wrens, honeyeaters, and crows. However, subsequent molecular research (and current consensus) places the robins as a very early offshoot of the Passerida (or "advanced" songbirds) within the songbird lineage. Testing of the nuclear and mitochondrial DNA of Australian members of the genus Petroica suggests that the pink and rose robins are each other's closest relative within the genus.<p>The generic name Petroica derives from the Ancient Greek petros 'stone' and oikos 'house'. The specific name rodinogaster derives from the Ancient Greek rhodinos 'pink' and gaster 'belly'.

Seychelles Paradise-Flycatcher
Terpsiphone corvina
Unusual and distinctive paradise-flycatcher. Adult males are completely glossy blue-black with extremely long tail streamers. Female has a black head, rufous upperparts, and white underparts, and lacks tail streamers. Both sexes have a blue ring of bare skin around the eye. Endemic to the Seychelles, where it is found mainly on the islands of La Digue and Denis. Habitat is thick indigenous woodland. A restless, active bird of middle levels of the forest. Calls include a tearing “shreeet” and an agitated twittering. The song is a long, musical, slightly descending series of “twee” notes.
Tumbes Swallow
Tachycineta stolzmanni
Desert-loving swallow of northwestern Peru; occasionally (perhaps seasonally) crosses over the border into southwestern Ecuador. The only swallow in its limited range with a white rump. Underparts are faintly streaked, though this is only evident from close range. Entirely white lower underparts help separate it from Blue-and-white Swallow. Usually seen in pairs or small groups circling over desolate habitat or perched atop a small bush or tree.
Desert Finch
Rhodospiza obsoleta
This subtly handsome finch is unique in its range; warm sandy brown with bright pink and silver flashes in the wings. Sexes are similar, but the male boasts a restricted black mask extending from the front of the eye to the base of the stout charcoal-black bill, which the female lacks. Not restricted to deserts but generally does prefer dry, open areas in middle to high altitude regions. Frequents villages, towns, and even cities. Gives a tumbling series of random-sounding notes, usually with a rather hoarse, buzzy quality. Calls include “chip” and “chink” notes and buzzy wheezes.
