Fernwren
Oreoscopus gutturalis
Small scrubwren-like bird found in wet rainforests at higher elevations in the Atherton Tablelands of far northern Queensland. Adult entirely brown except for white throat, black bib, and faint pale supercilium. Juvenile almost completely dark brown, with a faint hint of pale throat and brow. Forages on the ground in deep leaf litter. Call a series of high-pitched, penetrating notes followed by a longer note.
识别特征
The fernwren has a white eyebrow and throat, enclosing a dark brown face. Beneath the white throat, it has a black bib. It has a long-slender bill. The upperparts are dark olive-brown and the underparts paler. It is 12–14 cm (4.7–5.5 in) in length. The female is very similar to the male. Juveniles are dark brown without the white facial markings of the adult.
分类信息
The fernwren was first described by the English zoologist and ornithologist Charles Walter De Vis in 1889, and grouped with the scrubwrens as Sericornis gutturalis. It was later included in the genus Crateroscelis, along with three species of mouse-warblers found in New Guinea, but was subsequently moved to the monotypic genus Oreoscopus (established by North in 1905). The fernwren is a basal (subfamily) member of Acanthizidae and sister to the genus Pachycare.<p>The generic name Oreoscopus derives from the Ancient Greek oros meaning 'mountain' and scopos meaning 'guardian' or 'watcher'. The specific epithet gutturalis is Mediaeval Latin for 'of the throat', referring to the prominent white throat of this species. It was also known colloquially as the collared scrubwren.

分布与栖息地
The fernwren is found in northeast Queensland rainforest between 300–1,500 m (980–4,920 ft) above sea-level, although more often above 650 m (2,130 ft). It is found in the Paluma Range, near Townsville, and from the Tully Gorge National Park northwards to Cape Tribulation. It is sedentary and classified as endangered on the IUCN Red List.

行为
The fernwren forages in the moist leaf-litter amongst the ferns and dense shrubbery, particularly in shady gullies of highland rainforests. As it searches through the accumulated debris of the forest floor, it frequently bows its head and flicks its short tail. It feeds on arthropods and small skinks (Scincidae). It has a variety of calls, including high-pitched squeaks and whistles, a softer chattering sequence, and a buzzing, scolding call.

Village Indigobird
Vidua chalybeata
Nest parasite that lays its eggs in the nests of Red-billed and Brown firefinches. Breeding males are glossy black, while females and non-breeding males are streaky and brown on the back and pale below, with a bold facial pattern. The color of the bill is red in southeast Africa and whitish in western, northern, and central Africa. Found in savanna, scrub, farmland, and towns. Mimics the vocalizations of its host firefinches: low rattling series and high-pitched whistled notes. In southeast Africa, can be separated from other indigobirds by its red bill. Very similar to other indigobirds elsewhere on the continent. Breeding males can be separated by their all-black wings that lack a pale brownish panel. The mimicked vocalizations of its host species can also help confirm identification. In non-breeding plumage, similar to non-breeding Pin-tailed Whydah but separated by red legs.
Crested Doradito
Pseudocolopteryx sclateri
A small flycatcher with bright yellow underparts, a shaggy crest, and three wingbars. Inhabits marshes and flooded grasslands with overgrown vegetation. The song is a very soft and squeaky series of “tsik-tsik-tsee-lee” notes. Other doraditos have no wing marks.
Nullarbor Quail-thrush
Cinclosoma alisteri
Heavily patterned terrestrial bird of Nullarbor Plain. Both sexes have pale eyebrow, brown back, and black-and-white markings on wing. Female has buff chin and moustache, white belly, and pale gray chest, male a white moustache, black throat patch that connects to thick black breast band (forming an upside-down "T"), and brown sides. Note that male Copperback Quail-thrush has black chest. Usually seen walking around in very open low shrubland. Calls include a long, high-pitched whistled "seeeep."
