Pacific Baza

Aviceda subcristata

The Pacific baza (Aviceda subcristata), also known as the crested hawk, crested baza, and Pacific cuckoo-falcon, is a slender, medium-sized species of hawk in the family Accipitridae. It is mostly grey, brown, and white coloured and grows to a length of 35–46 centimetres (14–18 in). It is an omnivore and usually does not migrate. The breeding season for the species lasts from September to at least February, during which time specimens commonly fly and vocalise for display. It lives in Australia, Indonesia, Papua New Guinea, Solomon Islands, and East Timor, in forests, savannas, and freshwater bodies. The International Union for Conservation of Nature lists it as a least concern species.
