PEACOCK

A peacock is technically the male of any of various large pheasants. The name is most often used for the common peacock (Pavo cristatus), a bird of the pheasant family, native to southern Asia. It is rather larger than a pheasant. The male has a large fan-shaped tail, brightly coloured with blue, green, and purple 'eyes' on a chestnut background. The female (peahen) is brown with a small tail.
