A field team tracking the comings and goings of Mexican wolf packs in eastern Arizona has recovered a dead female wolf.

The Arizona Game and Fish Department says a Mexican wolf Interagency Field Team made the discovery Aug. 22 during routine pack monitoring activities.

The field team was alerted when a signal went off from a collar attached to the female wolf’s neck.

The wolf was recovered by a U.S. Fish and Wildlife Service agent and Game and Fish personnel the following day in the pack’s traditional territory on the Apache-Sitgreaves National Forest.

A preliminary exam by Mexican wolf project personnel failed to reveal an obvious cause of death. The wolf was sent to the National Fish and Wildlife Forensics Lab in Oregon for a complete necropsy.
