Pneumonia in Rocky Mountain Bighorn Sheep
Marsh HH. 1938. Pneumonia in Rocky Mountain Bighorn Sheep. Journal of Mammalogy. 19(2):214-219
For the past 13 years, reports have come to the Montana veterinary laboratories in Helena and Bozeman of disease losses in the Rocky Mountain bighorn sheep. The first investigation to determine the cause of the losses was made in 1924 in the Sun River Game Preserve, and since that time several investigations have been made in that region and in Glacier National Park, Yellowstone National Park, and the National Bison Range. The work has been done by the Montana Livestock Sanitary Board and the Montana Veterinary Research Laboratory, in cooperation with the U. S. Bureau of Animal Industry, the National Park Service, U. S. Forest Service, and the Montana Fish and Game Commission. Recently in an independent study of the bighorn losses in Glacier National Park has been made by Wildlife Technician R. M. Bond, of the National Park Service, in which the Montana Veterinary Research Laboratory participated in a consulting capacity. These investigations show that the losses have been caused by respiratory diseases of two types. The condition that has been the most prevalent has been somewhat chronic pneumonia that has caused death principally in mature sheep. The second type of disease has been observed on the National Bison Range, where an acute pneumonia has killed lambs at the age of two to three months.
