Pheasant
Pheasants () are birds of several genera within the family Phasianidae in the order Galliformes. Although they can be found all over the world in introduced (and captive) populations, the pheasant genera native range is restricted to Eurasia. The classification "pheasant" is paraphyletic, as birds referred to as pheasants are included within both the subfamilies Phasianinae and Pavoninae, and in many cases are more closely related to smaller phasianids, grouse, and turkey (formerly classified in Perdicinae, Tetraoninae, and Meleagridinae) than to other pheasants. Pheasants are characterised by strong sexual dimorphism, males being highly decorated with bright colours and adornments such  as wattles. Males are usually larger than females and have longer tails. Males play no part in rearing the young. Pheasants eat mostly seeds, grains, roots, and berries, while in the summer they take advantage of insects, fresh green shoots, spiders, earthworms, and snails. The best-known is the common pheasant, which is widespread throughout the world, in introduced feral populations and in farm operations. Various other pheasant species are popular in aviaries, such as the golden pheasant ("Chrysolophus pictus"). Etymology. According to the "Oxford English Dictionary", the word "pheasant" ultimately comes from Phasis, the ancient name of what is  now called the Rioni River in Georgia. It passed from Greek to Latin to French (spelled with an initial "f") then to English, appearing for the first time in English around 1299. Species in taxonomic order.
