"Standing Over" and "Hugging" in Wild Wolves, Canis lupus

L. David Mech

Abstract: During six summers, I observed "standing over" (SO) and "hugging" in a pack of wild Wolves (Canis lupus) habituated to me. In SO, one Wolf positions its groin above a recumbent Wolf's nose. I observed SO among all yearling and older Wolves for 1-180 seconds ( mean of X

= 69 ± 46 S.D.; N = 16). SO appeared to be primarily female-oriented and may inform each Wolf of the reproductive status of the other. I observed "hugging" five times and only during years when food competition was minimal.

Key Words: Wolf, Canis lupus, behavior, standing over, affection, reproduction.
