Adult eastern gray squirrels influence recruitment into local populations by directing aggression at juveniles and nonresidents. However, the role of juveniles in the social dynamics of squirrel populations is poorly understood. Field interactions among juvenile squirrels were studied between littermates and nonlittermates. Amicable interactions occurred only between littermates, while aggression was directed almost exclusively at nonlittermates. Juveniles within their own natal areas dominated nonresident juveniles. Interactions among juveniles appear to be influenced by kinship and may be important in determining recruitment patterns in squirrel populations.
