Defending a Territory

Winter Range: Not all Bald Eagles migrate—only those in the farthest northern and southern ranges are truly migratory, though resident eagles in between may travel considerable distances in winter seeking food. In general, eagles that nest south of the upper Great Lakes plus most eagles living in the maritime provinces and New England do not migrate.

Bald eagles select a breeding territory based upon an evaluation of all the things they are looking for; food supply, suitable nesting and perching trees, and isolation from excessive human activity. These areas are usually near where they themselves fledged as youngsters. Wintering birds do not establish a territory, but usually do use the same area each winter.

Caption Page: Dealing with Neighbors
Eagles spend their first days dealing with their neighbors, if any. They will often position themselves at the edge of their territories as a signal to others to stay out. When an eagle inadvertently flies too close or through an occupied territory, the resident adults will give chase, and in extreme cases, engage in aerial tumbling and even talon-locking.
