The pink robin (Petroica rodinogaster) is a small passerine bird native to southeastern Australia. Its natural habitats are temperate forests and subtropical or tropical moist lowland forests. 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. source
