A brightly-colored, long-tailed parrot of forest and clearings from the foothills to the mid-mountains. Males have a red head and underparts, blue rump and back of the neck, dark wings and a pale green shoulder bar. Females in the east have green head and upperparts with a red belly. In the west they more resemble the male. Similar to Moluccan King-Parrot but where the ranges meet, but Papuan King-Parrot has a pale green shoulder bar. Call, a series of clear, high, piping notes given at slightly different pitches.
