Hilary Cooley/U.S. Fish and Wildlife Service Colorado biologists say they have recorded multiple sightings of wolf pups born in Colorado. Note that, yes, this is a grey wolf pup, but not one of the recent sightings captured. It’s the pup-date Colorado wolf watchers have been waiting for. Colorado Parks and Wildlife on Wednesday confirmed that a litter of gray wolf pups is living in the state. The announcement marks the first evidence of wolf breeding in Colorado since the 1940s, when trappers and hunters eradicated the species with the support of the federal government. According to an agency news release, a state biologist and district wildlife manager observed multiple pups with a pair of adult wolves, known as M2101 and F1084. Other agency staff members have recorded three separate observations between June 4 and June 8.
