A fourth gray wolf that was brought to Colorado from Canada as part of the state’s reintroduction program has died, Colorado and federal officials confirmed on Friday morning.
This wolf was a female and died in northwest Colorado in an unknown location on Thursday, Colorado Parks and Wildlife (CPW) and the U.S. Fish and Wildlife Service (USFWS) said.
As with any wolf death in Colorado, the USFWS is investigating because gray wolves are a federally listed species under the Endangered Species Act. The USFWS will determine its cause of death. That investigation is ongoing.
No other details were available from either agency.
Fifteen wolves were brought to Colorado from Canada in January 2025 during the second round of reintroductions. As of publishing time, two males and two females have died:
