SPECIES BELONGING TO the birds-of-paradise family Paradisaeidae are decidedly the most beautiful birds in the world.
So when you’re considered one of the most iconic members of this family, you’re doing pretty well for yourself.
But like an unattainable muse, the stunning Wilson’s bird-of-paradise (Cicinnurus respublica) from New Guinea remains one of the most poorly known species of the family.
Confined to the tiny islands of Waigeo and Batanta in the Raja Ampat, or ‘Four Kings’, archipelago off the west coast of the Bird’s Head Peninsula in West Papua, the Wilson’s bird-of-paradise is unmistakable with its bright crimson back, yellow cape, shimmering green chest, blue feet, and most of all, its remarkable turquoise crown.
This segmented cap isn’t feathered, but is actually a patch of bare skin, and together with the species’ spiralled twin tail feathers, plays a crucial role in its complex courtship displays.
Male birds of paradise are the pretty ones
As with many birds-of-paradise, Wilson’s bird-of-paradise males alone carry this suite of striking colours, while the females are more plainly dressed in a light brown plumage with a darker blue crown.
To capture a female’s attention, a male will create an arena, or court, on the forest floor by clearing away leaves and other debris.
Against this suitably plain background, he will perch in front of an interested female, flitting from one vertical sapling to another, as he calls, chatters, and buzzes at her, distorting his body shape in various ways by puffing up his iridescent plumage.
He’ll flick his head, stretch his neck, and cock his tail and sometimes gape at her in an effort to win her affections.
