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 forehead spot and pink breast, with 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.

Elizabeth Gould, née Coxen (1804—1841), was a British artist and illustrator at the forefront of the natural history movement. Elizabeth traveled and worked alongside her husband, naturalist and author John Gould. She produced illustrations and lithographs for ornithological works, including plates in Darwin's The Zoology of the Voyage of H.M.S. Beagle and the Goulds' seminal work The Birds of Australia. In total, Elizabeth is accredited to at least 650 works. While in Australia, Elizabeth made hundreds of drawings from specimens for the publications Birds of Australia and A Monograph of the Macropodidæ, or Family of Kangaroos, as well as illustrations for the ornithology volume of Charles Darwin’s Zoology of the Voyage of HMS Beagle
