Monitoring flights have picked up pups in all 12 Yellowstone National Park wolf packs this year and so far pup survival looks good through July, according to the U.S. Fish and Wildlife Service.
Yellowstone National Park researchers also report that the summer predation study is going well. Approximately 31 kills have been found from mid-May through mid-July. The kills consisted of 20 bull elk, five cow elk, five calf elk, and one mule deer. The results thus indicate that rather than killing a lot of calves, wolves are preying on a lot of bulls.
