Butcherbirds are Australian magpie-like birds. Most are found in the genus Cracticus, but the black butcherbird is placed in the monotypic genus Melloria. They are native to Australasia. Together with three species of currawong and two species of peltops, butcherbirds and the Australian magpie form the subfamily Cracticinae in the family Artamidae. Butcherbirds are large songbirds, being between 30 and 40 cm (12–16 in) in length. Their colour ranges from black-and-white to mostly black with added grey plumage, depending on the species. They have a large, straight bill with a distinctive hook at the end which is used to skewer prey. They have high-pitched complex songs, which are used to defend their essentially year-round group territories: unlike birds of extratropical Eurasia and the Americas, both sexes sing prolifically. Butcherbirds are insect eaters for the most part, but will also feed on small lizards and other vertebrates. They get their name from their habit of impaling captured prey on a thorn, tree fork, or crevice. This "larder" is used to support the victim while it is being eaten, to store prey for later consumption, or to attract mates.
