Pheasants (/ˈfɛzənt/) are birds of several genera within the subfamily Phasianinae, of the family Phasianidae in the order Galliformes. Though they can be found world over in introduced (and captive) populations, the pheasant genera native range is restricted to Asia. Pheasants are characterised by strong sexual dimorphism, males being highly decorated with bright colors and adornments such as wattles. Males are usually larger than females and have longer tails. Males play no part in rearing the young.
