Large841 gForest

The palm cockatoo is 55 to 60 cm (22 to 24 in) in length and weighs 910–1,200 g (2.01–2.65 lb). It may be the largest cockatoo species and largest parrot in Australia, although large races of yellow-tailed black cockatoos and sulphur-crested cockatoos broadly overlap in size. It is a distinctive bird with a large crest and has one of the largest bills of any parrot (only the hyacinth macaw's is larger). This powerful bill enables palm cockatoos not only to eat very hard nuts and seeds, but also enables males to break off thick (about 1 in (2. Voice: The vocalizations of palm cockatoos are similar to those of most wild parrots, but they have also been shown to produce a variety of additional syllables in display and exchange with neighbouring individuals. These additional syllables are mainly produced by males and are often combined to form long, complex sequences. In a population in the Iron Range, 30 different syllables were distinguished.

Tanimbar Corella

Cacatua goffiniana

Medium275 gForest

Tanimbar corellas weigh, on average, about 250 g (9 oz) for females and 300 g (11 oz) for males. They are about 31 cm (12 in) from head to tail. Like all members of the family Cacatuidae, the Tanimbar corella is crested, meaning it has a collection of feathers on its head that it can raise or lower. Its body is mainly covered with white feathers, with salmon- or pink-coloured feathers between the beak and eyes.
