Sylvilagus nuttallii Nuttall's Cottontail Sylvilagus nuttallii occurs over much of the western United States. In Colorado, it characteristically inhabits edge situations in forests at moderate elevations. In the north- western part of the state and in the San Luis Valley, treeless areas are occupied, but typi- cally only where a cover of brush is well de- veloped. Seldom are areas utilized as open as those favored by Sylvilagus audubonii.
