Papuan/Green-winged King Parrot

Alisterus chloropterus 

The Papuan or Green-winged King Parrot comes from Papua New Guinea. The male has much more vivid colours including a brighter red, a brighter blue and (despite its name) more blue in its dark green wings which gives more contrast to the almost luminous light green streak.

The parrot illustrated above is one of three sub-species with distinct ranges: Alisterus chloropterus moszkowskii. Unlike the two other sub-species, the female resembles the male with a red head, but is paler and has a much less contrasting wing-stripe. The females of the other two sub-species (chloropterus and callopterus) have green heads.

Moluccan/Amboina King Parrot

Alisterus amboinensis 

The six sub-species of the Moluccan King Parrot come from various islands of Indonesia (also called the Ambon/Amboina King Parrot although only the nominate sub-species (above) comes from Ambon Island). Unlike the two other King Parrots, the male and female Moluccans have similar plumage and lack the pale green wing-stripe.

The parrot above is the Moluccan sub-species known as the Buru King Parrot, Alisterus amboinensis buruensis, from Buru Island, central Moluccas.
It has a wholly black beak rather than the red and black. It also has a blue nape.
