This is the variety most often seen in zoos and parks.
Males are predominantly dark, royal blue with green iridescence through the tail.
The shoulders and sides of the blue male are checkered black and white. The hen is brown with a green neck. The cock and hen are identically colored like the blue. Through the plumage, white feathering, irregularly patterned, makes the bird look as though white paint has been thrown on the bird. This is a very attractive mutation of the blue.
