Peacock pheasants, named for their similarity to the eye feathers of the peacock, belong to the genus Polyplectron, which means many spurs. It is characteristic of peacock pheasants to have one or more sets of spurs on their legs. There are many species of peacock pheasants which inhabit various parts of Asia; therefore, they are tropical birds that require heat in northern climates. There is decent variation between the species, but the males of each species have moderately-sized tails marked with vibrant ocelli. During their breeding displays, the males open up their tails, just as a peacock fans his train.
