Summer Range: Bald Eagles’ breeding range spans the continent from Alaska to Newfoundland, and south to Baja California and Florida. In spring, eagles migrate in two stages: adults first, then immatures. They fly during daylight and often over ranges of hills and other areas of high relief where thermal updrafts facilitate their flight.
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.
