The Pheasant. 



Phasianus colchiciis, lyiXN. 



THE true Pheasants, of which our common species, the P. colchicus, of Linnaeus, 

 may be taken as the type, are all natives of Asia, extending from Asia 

 Minor as far east as Japan and Formosa. They are readih- distinguished from 

 other gallinaceous birds by the long wedge-shaped tail, composed of eighteen 

 feathers, the two central of which are much longer than the others, and in some 

 species, as the Reeves Pheasant, occasionally reach even six feet in length. There 

 is a large number of closely allied species, or local races, which readih' interbreed 

 with one another, and produce, not sterile hybrids, but fertile offspring. In 

 England, the species originally introduced was the Colchian Pheasant, P. colchicus, 

 from Asia ]\Iinor, which is now conimonlj^ known as the Old English Pheasant. 

 Since its introduction, which took place about a thousand years ago, the Chinese 

 Ring-necked Pheasant, P. torquatus, has been introduced, and also the Japanese 

 species, P. vcrsico/or. These having been introduced into our coverts, have interbred 

 freel}^ and now it is not easy to secure a specimen of either one of the races that 

 can be regarded as perfectly pure. 



Since its introduction from the east, the Pheasant has spread over the greater 

 part of Europe, except in the Arctic regions. It has also been introduced and 

 flourishes exceedingly well in North America, Australia, and in New Zealand.
