Pheasants and Partridges (Phasianidae)

Ring-necked Pheasant (Phasianus colchicus) - HBW 2, p. 542

French: Faisan de Colchide German: Fasan Spanish: Faisán Vulgar
Other common names: Common Pheasant

Taxonomy: Phasianus colchicus Linnaeus, 1758, Africa, Asia = Rion River.
Sometimes considered conspecific with P. versicolor, which is thus relegated to subspecies level; however, the two are not now generally regarded as conspecific, because present species, when introduced to Japan, is apparently unable to survive, presumably due to competition with P. versicolor, and failure to hybridize successfully; nevertheless, they hybridize extensively where both introduced in Hawaii. Internal taxonomy of species requires extensive revision. Populations of E Asia sometimes considered to constitute a separate species, P. torquatus. Races currently acc.. View all taxonomy...

Taxonomy: Phasianus colchicus Linnaeus, 1758, Africa, Asia = Rion River.
Sometimes considered conspecific with P. versicolor, which is thus relegated to subspecies level; however, the two are not now generally regarded as conspecific, because present species, when introduced to Japan, is apparently unable to survive, presumably due to competition with P. versicolor, and failure to hybridize successfully; nevertheless, they hybridize extensively where both introduced in Hawaii. Internal taxonomy of species requires extensive revision. Populations of E Asia sometimes considered to constitute a separate species, P. torquatus. Races currently accepted can be split into five or six groups, which may be a better guide to geographical variation. Thirty one subspecies recognized.
