Summer activity of mountain sheep on Mt Washburn, Yellowstone National Park
Davis WB. 1938. Summer activity of mountain sheep on Mt Washburn, Yellowstone National Park. Journal of Mammalogy. 19(1):88-94
Records observations made on mountain sheep at Mt. Washburn from July 3 to July 21, 1934. A total of 138 hours was spent in following the sheep over their range, observations frequently beginning before dawn and ending after dark. Bighorn seemed to avoid forbs and sedges, preferring grasses, and to always prefer green vegetation over dried. Author estimates sheep grazed 95% of feeding time during July. Peak lambing was mid-June.
