White-breasted Robin

The white-breasted robin (Eopsaltria georgiana) is a passerine bird in the Australasian robin family Petroicidae. It was often previously placed in the genus Quoyornis. It is endemic to southwestern Australia. Unlike many other Australian robins, it lacks bright colours in its plumage, being a predominantly greyish bird with white underparts. Like other closely related Australasian robins, it is a cooperative breeder. It is sedentary, with pairs or small groups maintaining territories. == Taxonomy == The white-breasted robin was first described by the French naturalists Jean René Constant Quoy and Joseph Paul Gaimard in 1830 as Muscicapa georgiana, taking its name from the site King George Sound, where the authors had collected specimens. It was later described by John Gould in 1846 as Eopsaltria leucogaster, though as the former took precedence, its specific name remains georgiana. Australian amateur ornithologist Gregory Mathews described a paler specimen from Warren River as a distinct subspecies warreni, though this was not recognised subsequently. The white-faced robin was formerly the only species placed in the genus Quoyornis that had been introduced by Mathews in 1912, but based on a 2011 molecular genetic study by Les Christidis and coworkers, Quoyornis was merged into a more broadly defined…
