The pink robin (Petroica rodinogaster) is a small passerine bird native to southeastern Australia. Its natural habitats are cool temperate forests of far southeastern Australia. Like many brightly coloured robins of the family Petroicidae, it is sexually dimorphic. Measuring 13.5 cm (5.3 in) in length, the robin has a small thin black bill, and dark brown eyes and legs. The male has a distinctive white crown and pink breast, grey-black upperparts, wings and tail. The belly is white. The female has grey-brown plumage. The position of the pink robin and its Australian relatives on the passerine family tree is unclear; the Petroicidae are not closely related to either the European or American robins but appear to be an early offshoot of the Passerida group of songbirds. 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. Its range is forests of southern Victoria and neighbouring parts of South Australia and New South Wales, and Tasmania. Breeding occurs from September to January. The nest is a well-made, neat, deep cup of moss. Spider webs, feathers and fur are used for binding or filling, and the nest is generally placed in a tree fork up to 5 m (15 ft) above the ground. A clutch of three or four eggs is laid. The eggs, which measure 18 by 14 mm, are greyish-, greenish- or blueish-white, and are marked with dark brown and lavender splotches and spots, usually concentrated around the large end. Prey consists of a variety of spiders and insects, including caterpillars, ichneumon wasps, beetles, flies and ants. - https://en.wikipedia.org/wiki/Pink_robin
The gang-gang cockatoo (Callocephalon fimbriatum) is found in the cooler and wetter forests and woodlands of Australia, particularly alpine bushland. Mostly mild grey in colour with some lighter scalloping (more pronounced and buffy in females), the male has a red head and crest, while the female has a small fluffy grey crest. It ranges throughout south-eastern Australia. The gang-gang cockatoo is the faunal emblem of the Australian Capital Territory. It is easily identified by its distinctive call, which is described as resembling a creaky gate, or the sound of a cork being pulled from a wine bottle. The name gang-gang comes from a New South Wales Aboriginal language, probably from one of the coastal languages, although possibly from Wiradjuri. It is probably an onomatopoeic name. Unlike most other cockatoos, gang-gangs nest in young, solid trees, the females using their strong beaks to excavate nesting cavities. Also, they breed in the canopy of most trees. They are sexually dichromatic. Loss of older, hollow trees and loss of feeding habitat across south-eastern Australia through land clearing has led to a significant reduction in the numbers of this cockatoo in recent years. As a result, the gang-gang is now listed as vulnerable in New South Wales. The gang-gang cockatoo was most often allied with the white cockatoos of the genus Cacatua. This has always been controversial due to the unusual appearance and coloration of the bird, especially its sexual dichromatism. New research has finally resolved the matter, with the gang-gang cockatoo being recognized as a distinctive early offshoot of the calyptorhynchine (dark) cockatoos. Considering the robust phylogeny of the cockatoos now established, a comparison of characteristics gained and lost during the evolution of cockatoos suggests that the gang-gang cockatoo—while of course much changed and adapted during the perhaps 20 million years since its last common ancestor with any other living species lived—is probably still very similar in overall appearance to how the earliest cockatoos would have looked, and certainly the most primitive-looking of the species alive today. - https://en.wikipedia.org/wiki/Gang-gang_cockatoo
