The Pacific baza, known also as the crested hawk or Pacific cuckoo-falcon, is a medium-sized hawk with a slender build. It boasts a mix of grey, brown, and white plumage and measures between 35 to 46 centimeters in length. This omnivorous bird is typically non-migratory and is recognized by its small crest on the nape.
Adult Pacific bazas have a white underside with black barring, a grey head with a partially domed shape, and yellow eyes set far back on the head. Their thighs are reddish-brown, and their feet are grey. In flight, their broad, rounded wings display distinct bands and are large relative to their body size. The tail is long with a square end and black tip, matching the body in length.
These birds inhabit subtropical and tropical forests, dry savannas, and freshwater bodies, including wetlands, streams, and rivers. They are typically found at elevations below 1,000 meters, though they can occasionally be spotted up to 1,300 meters.
The Pacific baza is found in the warmer, more humid regions of the Australasian realm. It breeds in Australia, Indonesia, Papua New Guinea, and the Solomon Islands, and is also a resident in East Timor.
Pacific bazas are known for their unobtrusive and docile nature. They are social birds, often gathering in groups outside the breeding season. Their diet includes fruits, insects, tree-frogs, lizards, snakes, and birds. They hunt by diving into foliage or snatching prey mid-air. During the breeding season, they perform soaring displays and vocalize distinct "pee-peow" calls.
The vocal repertoire of the Pacific baza includes a two-note call, starting with a rising pitch followed by a more explosive descending note.
Breeding season commences in September and can extend beyond February in some regions. The Pacific baza builds flimsy stick nests high in tree branches and lays 1-4 white, occasionally spotted eggs. Both parents share incubation duties, with shifts typically lasting around 1.5 hours.
The long-tailed honey buzzard may be mistaken for the Pacific baza, but it can be distinguished by its less-rounded wings and a breast that is barred rather than streaked.
Pacific bazas are omnivores, consuming a varied diet of fruits, insects, and small vertebrates. They have been observed to intentionally eat fruit, contrary to earlier beliefs that their fruit consumption was accidental.
The International Union for Conservation of Nature (IUCN) lists the Pacific baza as a species of Least Concern, thanks to its large range and stable population. It is also part of the international pet trade.
