Strepera graculina. More of a bird in habitat photo (a grab shot taken through a window yesterday)
"Pied Currawongs feed on a variety of foods including small lizards, insects, caterpillars and berries. They also take a large number of small and young birds, especially around urban areas where suitable cover is scarce. Larger prey, up to the size of a young possum, is also taken, and birds will occasionally hunt as a group. Prey may be stored in a 'larder' (hung on a hook or in a tree fork or crevice) and either eaten straight away or, in the case of larger prey, over a period of time."
