The grey currawong (Strepera versicolor) is a large passerine bird native to southern Australia and Tasmania. One of three currawong species in the genus Strepera, it is closely related to the butcherbirds and Australian magpie of the family Artamidae. It is a large crow-like bird, around 48 cm (19 in) long on average, with yellow irises, and a heavy bill, and dark plumage with white undertail and wing patches. The male and female are similar in appearance. Six subspecies are recognised and are distinguished by overall plumage colour, which ranges from slate-grey for the nominate from New South Wales and eastern Victoria and subspecies plumbea from Western Australia, to sooty black for the clinking currawong of Tasmania and subspecies halmaturina from Kangaroo Island.
