The number of poults per brood and poults per female was higher than the respective figures for the previous two years (Dusek and McCann 1973 and 1974). Pronghorn Distribution and population data concerning pronghorn antelope during the report period were obtained from aerial surveys during July 1974. Observations of this species in the Bull Mountains during fall and winter were Distribution During the report period data were gathered only in hunting district 540. Most observations were obtained in the Buffalo Creek and Railroad Creek drainages in northern Yellowstone County. That area was characterized by rolling topography with big sagebrush-grasslands and grasslands inter- spersed with timbered ridges. Fewer observations of pronghorn were ob- tained in southern Musselshell County which was characterized by rougher topography and more timber than occurred in Yellowstone County. The distribution of pronghorn followed a pattern similar to that observed during the previous summer (Dusek and McCann 1974). Population Characteristics Fawn:doe and fawn:adult ratios for hunting district 540 during July 1974 were 25:100 and 17:100 based on a sample of 164 animals (Table 24). These production figures were less than those reported for the previous summer (Dusek and McCann 1974). -41-.
