Glossy Black-Cockatoo
Calyptorhynchus lathami
Smaller brownish-black cockatoo of eastern Australia. Male fairly plain except for bright red tail panels. Female has blotchy yellow patches on neck and face and orange-red tail panels. Large bill used to feed on Allocasuarina and Casuarina seeds. The species is entirely dependent on these trees, and recently chewed seed-cones are good indicators of their presence. Usually observed in small groups rather than large flocks. Calls include drawn-out notes with a rougher, croakier tone than Red-tailed and Yellow-tailed Black-Cockatoos.
识别特征
Like the related red-tailed black cockatoo, this species is sexually dimorphic. The male glossy black cockatoo is predominantly black with a chocolate-brown head and striking caudal red patches. The female is a duller dark brown, with flecks of yellow in the tail and collar. The female's tail is barred whereas the male's tail is patched. An adult will grow to be about 46–50 cm (18–19.5 in) in length. The birds are found in open forest and woodlands, and usually feed on seeds of the she-oak (Casuarina spp.)
分类信息
The glossy black cockatoo was first described by Dutch naturalist Coenraad Jacob Temminck in 1807. The scientific name honours the English ornithologist John Latham.<p>The glossy black cockatoo's closest relative is the red-tailed black cockatoo; the two species form the genus Calyptorhynchus. They are distinguished from the other black cockatoos of the genus Zanda by different tail colour and head pattern, significant sexual dimorphism, and differences in two juvenile call types, a squeaking begging call and a vocalization when swallowing food.<p>Three subspecies were proposed by Schodde et al. in 1993, although in 2002 parrot expert Joseph Forshaw had reservations due to their extremely minimal differences. Saunders and Pickup's (2023) detailed analysis of the species throughout its range demonstated there was no differentiation in bill morphology, little difference in genetic makeup, no differences in plumage pattern or colour, and no differences in diet, supporting Forshaw's reservations and they concluded the species is monotypic.

保护状况
Like most species of parrots, the glossy black cockatoo is protected by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) with its placement on the Appendix II list of vulnerable species, which makes the import, export, and trade of listed wild-caught animals illegal.<p>Glossy black cockatoos generally are not listed as threatened on the Environment Protection and Biodiversity Conservation Act 1999, however the Kangaroo Island subspecies (C. l. halmaturinis) was added to the list as endangered.<p>C. l. lathami is listed as vulnerable by the Queensland, Environmental Protection Agency.

Odedi
Horornis haddeni
A small, round-bodied, cock-tailed skulking warbler. Appears three-toned: dark slaty gray below, chestnut brown above, with a paler rufous head and a slightly darker eye-stripe. Prefers dense undergrowth and tangles in forest or on forest edge above 600 meters of elevation, but locally lower. Song is a high-pitched whistle “o-de-di.” Also gives harsh scolding notes.
Golden-bellied Gerygone
Gerygone sulphurea
Tiny and rather unobtrusive bird with brownish upperparts and luminous lemon-yellow underparts. Superficially similar to female and juvenile Olive-backed Sunbirds, but note gerygone’s short, uncurved bill. Forages in parks, forests, and plantations, where it often joins mixed flocks moving through the middle and upper layers. Song is variable throughout its range but invariably includes buzzy notes with obvious rises and falls in pitch.
Thamnornis
Thamnornis chloropetoides
Odd, warbler-like, long-tailed and long-billed tetraka. Madagascar endemic that is the only tetraka regularly found in spiny forest. Mostly skulks in the understory, but will sing from an open perch at the top of a tree. Song is a sputtering trill that is sometimes followed by a series of lower “chup” notes. Larger, longer-tailed, and longer-billed than jeries. More greenish than Subdesert Brush Warbler, with white tips to the tail, and without fuzzy breast streaks.
