title: Snowball construction by a feral troop of Japanese macaques (Macaca fuscata) living under seminatural conditions.
abstract: Feral Japanese macaques (Macaca fuscata) living under seminatural conditions in Oregon constructed several large snowballs in their two-acre corral. This behavior did not involve the basic reward systems connected with agonistic or feeding behavior which are most commonly associated with tool-using in nonhuman primates.
