Subspecies
Colinus virginianus (Sibley and Monroe 1990, 1993) was provisionally split into Northern Bobwhite (Colinus virginianus) and Colinus ridgwayi by Stotz et al. (1996) but this treatment has not been adopted by BirdLife International (2005).

Sometimes considered conspecific with Black-throated Bobwhite (Colinus nigrogularis). Several subspecies have at times been considered full species. Validity of subspecies nelsoni questionable.

The following 23 subspecies are recognised:

  • marilandicus (Linnaeus, 1758)   -  South-eastern Maine to central Virginia, north-eastern USA.
  • virginianus (Linnaeus, 1758)   -  Virginia to northern Florida and west to Alabama, eastern USA.
  • floridanus (Coues, 1872)   -  Peninsular Florida, eastern USA.
  • cubanensis (Gray, GR, 1846)   -  Cuba and I of Pines.

  • ridgwayi Brewster, 1885   -  North-central Sonora, Mexico; reintroduced to south-eastern Arizona, south-western USA, where extirpated in past. Considered by some authors to be a distinct species, Masked Bobwhite (Colinus ridgwayi).
