Distribution and Variation in the Native Sheep of North America
Cowan IM. 1940. Distribution and Variation in the Native Sheep of North America. The American Midland Naturalist. 24(3):505-580
This investigation examined 761 specimens of North American mountain sheep, forming the basis for a study of individual, seasonal, sex, age, and geographic variation in the genus. Ten geographic races were found to be recognizable on the basis of existing specimens. Published and unpublished material was used in an appraisal of the present distribution and abundance of the various races. Though mountain sheep populations are smaller, with localized extirpation in some regions, in North America some areas still exist where mountain sheep populations from which restoration of the species, up to the carrying capacity of the range, were available.
