A brightly colored, slender, long-tailed parrot of forest and clearings from the lowlands to mid-mountains in the northwest. Red head and underparts, long bluish tail, blue back, and green or bluish wings depending on the race. Similar to Papuan King-Parrot with little overlap, but Moluccan lacks the pale green shoulder bar of the male and green head of the female. Somewhat similar to Chattering Lory but Moluccan King-Parrot has a blue rather than red back and a longer tail. Gives clear, high-pitched, upslurred piping and harsh scolding calls.
