Paperbark Flycatcher
Myiagra nana
A sturdy songbird with fairly long tail, substantial bill. Glossy black above, bright white below. Female may show a buffy patch on upper breast. Similar to Restless Flycatcher; best identified by range. Inhabits wetlands, foraging near the ground/water. Compare Willie Wagtail. Calls loudly with a clear whistled "tui-tui-tui” and an incomparable buzzing scissors-grinder sound.
识别特征
The paperbark flycatcher is broadly similar to the restless flycatcher, with entirely black upperparts from the crown and sides of the head, in contrast with entirely white underparts from the throat to the vent. It is a smaller bird, at only two-thirds the weight of its southern relative, and has a proportionately shorter and broader bill, with longer and stouter rictal bristles. There is no overlap in size between the species. The back and the crown of nana are the same glossy black, while inquieta has a slightly paler, slate-grey, back. There are also differences in the vocalisations: nana almost never use the distinctive "scissors-grinding" call of inquieta.
分类信息
Originally described as Seisura nana by John Gould in 1870, the paperbark flycatcher was long treated as a subspecies of the restless flycatcher (M. inquieta), until 1999 when Schodde and Mason identified the distinctness and lack of intergrading in closely situated populations of the two parapatric taxa.

分布与栖息地
The flycatcher is found in northern Australia, from the Kimberley region of Western Australia, across the Top End of the Northern Territory, to the Gulf Country and south-western Cape York Peninsula of north-west Queensland, with a population on Saibai Island in Torres Strait. It is also found in southern New Guinea from Merauke eastwards to the Bensbach River in the Middle Fly District. The paperbark flycatcher does not overlap in distribution with the restless; although their ranges abut in northern Queensland there are no signs of intergradation between the two species, and in the area where the ranges meet most of the restless flycatchers are non-breeding migrants.<p>In Australia the paperbark flycatcher inhabits tropical eucalypt woodlands, paperbark woodlands and dry riverine woodlands. In New Guinea, where it is locally common along the lower reaches of the Bensbach River, it frequents scrub, partly submerged trees, and sedgeland bordering rivers on floodplains and savanna.

Rockwarbler
Origma solitaria
Small terrestrial bird of Hawkesbury Sandstone region of southern New South Wales. Brown above, reddish brown below, with paler throat. Tail held downward (not cocked like Pilotbird). This species hops around on rocky boulders and cliffs, flicking its tail from side to side. Calls include a repeated short "plik."
Asian House-Martin
Delichon dasypus
Small, compact swallow with dark (glossy dark blue) upperparts, smudgy gray cast on whitish underparts, and bright white rump. Very similar to Northern and Nepal House-Martins, with gray-smudged underparts intermediate between the clean white belly of the former and black sides of the latter. Sometimes mistaken for House Swift when seen from above, but the chunkier shape and broader wings of the swallow are distinctive. Often nests in bustling colonies on cliffs and under the eaves of human-made structures.
Jos Plateau Indigobird
Vidua maryae
A nest parasite that lays its eggs in the nests of Rock Firefinches. Breeding males are black with green iridescence and a pale brownish panel in the wings. Females and non-breeding males are streaky and brown on the back and pale below, with a bold facial pattern. The bill is whitish and the legs pale purple. A scarce, local, and poorly known species. Found in rocky areas within savanna. Given current knowledge, can only be confidently identified by vocalizations. Imitates the vocalizations of its host, Rock Firefinch, including soft “teew” whistles, a descending trill, “tep” notes, and “pit-pit-pit” calls. These are often mixed into a scratchy jumble of high-pitched notes.
