This is a mexican grey wolf or lobo. Yuma, a female mexican wolf that resides at Los Coyotes zoo in Mexico city was born at the Arizona Sonora Desert Museum. Yuma was the mother of 3 lobitos just last year. If you check out their pictures in the mexico gallery the family resemblance to the wolf in this picture ( which is lovely by the way) is evident. ASDM has one of the best records for breeding the endangered mexican grey wolves.
