ghostcat's Identifications

Found on Arizona Scenic Highway 83 in the northbound lane, near milepost 53. Adult female. We also found the presence of hairless babies (pregnant?). Photographed by SIA volunteer Charlotte Cook.

Comment on the ID: In the Madrean Sky Islands and Sonora, Mexico this opossum is called tlacuache, or Mexican brown-nosed opossum, and I believe it is classified as Didelphis virginiana, subspecies californica. Evidence of these opossum expanding further north into Arizona have been documented. Anyone know more about the genetics of these?
