The king parrots are three species of medium-sized parrots in the genus Alisterus; the Australian king parrot (A. scapularis), the Papuan king parrot (A. chloropterus), and the Moluccan king parrot (A. amboinensis). The three species are found in eastern Australia, New Guinea, and Indonesian islands including the Maluku Islands, respectively. Predominantly of red and green plumage, the long-tailed parrots are related to the genera Aprosmictus and Polytelis.
King parrots are medium-sized parrots, 35–43 cm (14–17 in) in length with long, broad tails. They have relatively small beaks for their size. The beaks of the adults are two colours, blackish and orange-reddish, except for the subspecies A. a. buruensis of the Moluccan king parrot which has a grey-black beak, and female Australian king parrot which has a grey beak.
The Papuan king parrot and the Australian king parrot show sexual dimorphism in their plumage and beak colouration, which contrast to the Moluccan king parrot, where the male and female have an identical external appearance.
The two subspecies of the Australian king parrot are similar except in size. The male has a red head and neck, red lower parts, blue back and rump, and green wings, each with a pale-green band (resembling a shoulder stripe). In the female, the head is green, the green being continuous over the neck, chest, and back. Red plumage covers the lower abdomen, and the pale-green wing band is small or absent. Juvenile males also have a green neck and head.
The three subspecies of the Papuan king parrot all show sexual dimorphism and in all three subspecies, the male can be identified by a prominent broad pale-green band on each wing. The differences in the females between subspecies are more marked than the differences in the males. The female of subspecies A. c. moszkowskii has green wings, and a red head, neck, chest, and abdomen resembling the male, and differs from the male with its much smaller pale-green wing band. The females of A. c. chloropterus and A. c. calloterus differ from the males with broadly similar sexual dimorphism to the Australian king parrot with extended green plumage, except the chests of the females of these two Papuan king parrot subspecies have vague transverse green and red striations.
