Collared Sparrowhawk

Accipiter cirrocephalus

The collared sparrowhawk is a small, slim bird of prey in the family Accipitridae found in Australia, New Guinea and nearby smaller islands. It was formerly placed in the genus Accipiter. As its name implies the collared sparrowhawk is a specialist in hunting small birds. It is characterised by its slight brow ridges and slender feet. The last segment of their middle toe projects beyond the claws of the other toes. Source
