The first captive breeding of this species was by Sten Bergman of Sweden in 1958. He was awarded a commemorative medal by the Foreign Bird League to mark this achievement.

Description

This so-called "living gem" is the smallest and most vividly colored among birds-of-paradise. The king bird-of-paradise is small, measuring approximately long, but if central rectrices of adult males included. Females weigh about , males . The adult male has an overall metallic crimson color, slightly orange under certain lights, and more particularly so in the crown. They have a narrow, dark green iridescent breast band with whitish lower breast, and green-tipped fan-like plumes on the shoulder. The feathers of the undertail and mantle are olive-brown, with iridescent green tips, and violet legs. Bills are ivory-yellow. Females have dull olive heads and upperparts with yellowish underparts and violet legs.

Ecology and behaviour

There is little information available about this species' behavior. They are inconspicuous and may be hard to locate, except for males at their display trees.


Courtship and breeding

, with the promiscuous adult males displaying in isolation at exploded leks and in groups at traditional arboreal courts. They are perhaps more persistent callers than any other birds of paradise. Courtship involves complex vocalizations, feather manipulations, and a variety of body posturing and movements, including hanging fully inverted and pendulum-like swinging. An extraordinary

occurs at least during March through October. The open cup nest is built into a tree cavity (unique within the family), within which two eggs are laid. The female builds the nest and cares for the young without male assistance. In captivity, incubation lasted 17 days and the nestling period was 14 days.

. Foraging occurs at all forest levels, where birds often join mixed-species foraging flocks to seek arthropods in the lower forest.


Conservation status

The species is tentatively assessed as being in decline due to habitat loss and unsustainable levels of hunting. However, despite the fact that the population trend appears to be decreasing, being a widespread and abundant species throughout their large habitat range, the king bird-of-paradise is evaluated as Least Concern on the
