Gray wolves are currently federally listed under the Endangered Species Act in Colorado. As such, when a wolf dies in the state, the necropsy and investigation into the death are performed by the U.S. Fish and Wildlife Service. Initial results from necropies have taken anywhere from 1 month to 4 months to be released by the federal agency.
