King Bird of paradise
The king bird-of-paradise (Cicinnurus regius) is a passerine bird of the Paradisaeidae (Bird-of-paradise) family.
The king bird-of-paradise is distributed throughout lowland forests of New Guinea and nearby islands. The diet consists mainly of fruits and arthropods.
An extraordinary courtship display is performed by the male with a series of tail swinging, fluffing of its white abdominal feathers that makes the bird look like a cottonball, and acrobatic movements of its elongated tail wires. source
