. Ecology of sympatric populations of mule deer and white-tailed deer in a prairie environment . 1 2 3 4 5 6 7 8 9 10 11 12 MONTH Fig. 18. Monthly patterns of habitat use by radioed female white-tailed deer on the Cherry Creek area, 1983-1985, relative to habitat availability. Habitat use and selection during autumn generally followed that for summer (Table 20), except that grainfields received increased use and were highly selected. This autumn shift to grainfields was the most significant change in habitat use by white-tailed deer through the year, and reflected movement of many deer to harvested fields to feed on waste grain. It involved large shifts in centers of activity and increased home range size among radioed females. Overall, hardwood draws continued to receive heaviest use; mesic shrublands received moderate use and were selected. Although sagebrush grasslands and legume hayfields also were selected, use of both was relatively minor. Mixed prairies, which received moderate use, bunchgrass prairies, and badlands were generally avoided. During winter, whitetails heavily and selectively used hardwood draws (Table 20). Bunchgrass prairies and grainfields also appeared to be generally selected. Use of mesic shrublands and sagebrush grasslands was only in proportion to availability. Mixed prairies and badlands were avoided, though both received moderate use. Legume hayfields appeared to be used only rarely in winter. 65
