Andean Negrito
Lessonia oreas
Tiny little terrestrial flycatcher, fairly common locally in open habitats of the high Andes, especially bogs and lakeshores. Feeds mainly by hopping on the ground, but perches readily on posts and fences. No similar species in range: male is black with a bright rusty back; female is dark sooty brown with a dull rusty back. In flight both sexes show whitish flash in wings (absent in Austral Negrito, which occurs in lowlands to the south).
识别特征
The Andean negrito is around 12.5 cm (4.9 in) long, with males being slightly larger. It is sexually dimorphic in its plumage; males having black plumage with a rufous back and silvery-white flight feathers (that are only noticeable in flight). The female has a rufous back as well but the undersides and head are sooty and the upperparts are blackish brown. The throat is whitish and the breast tinged with dull rufous. The species has exceptionally long hindclaws, like those of a pipit.

分布与栖息地
The Andean negrito ranges through the mountainous regions of central Peru south into western Bolivia, down into north eastern Chile and northern Argentina. It is most commonly found between 3,000 and 4,000 m (9,800 and 13,100 ft) above sea level, but may go higher in Peru or drop down to 1,000 m (3,300 ft) in Chile. It lives around lakes, streams and bogs and in seasonally flooded plains, in areas with low ground cover. The species is non-migratory.

行为
The Andean negrito is a terrestrial insect hunter that is found in pairs or small family groups. It often perches on elevated tussocks or rocks to watch for prey. Prey is either sallied after on the wing from on or close to the ground, or chased after on foot.<p>Little is known about its breeding behaviour. In Chile it breeds between October and January. Males perform a fluttering display flight that goes 10–15 m (33–49 ft) in the air. Nests are simple cups hidden inside tussock grass, into which 3–4 eggs are laid.

Australasian Swamphen
Porphyrio melanotus
Conspicuous blue and black waterhen with gigantic red bill and forehead shield. Has large feet and white under tail feathers which it flicks up and down when walking. Occurs in a wide variety of wetland habitats and is a common sight in urban parks. They are very vocal, often making loud crowing calls and a range of other shorter squawks, including a single note squawk at night.
Slaty-backed Thornbill
Acanthiza robustirostris
Small bird with thin pointed bill, uncommon in mulga woodland of arid inland temperate Australia. Brownish gray above, cream-colored below, with dark eye, dark streaking on forecrown, pale lores, pale-tipped dark tail, and chestnut rump, often visible in flight. Usually seen in pairs or singly, foraging low in branches rather than on the ground. Distinguished from juvenile Chestnut-rumped Thornbill (which also has dark eyes) by noting the dark streaks on Slaty-backed’s forehead. Typical calls are thin chatter and a clear, reeling trill.
New Zealand Pipit
Anthus novaeseelandiae
Endemic pipit found in open habitats from coastline to alpine shrublands. Scarce in intensively farmed areas. Prominent pale eyebrow with brown streaked upper body, pale underparts and brown streaking on breast. Distinctive 'tzweep' call given year round. Repeated high-pitched 'pip-it' territorial song heard mainly in August-February. Often seen walking rather than hopping, frequently flicking their long tail when they stop, or when perched. Can form loose flocks in autumn and winter. Very similar to introduced Eurasian Skylark. Note lack of large head crest, a more slender body, and distinctive habit of wagging its long tail up and down.
