Great Blue Heron Migration

Summer Range: Great Blue Herons breed across most of North America south of southern Canada to the Gulf states, Central America and the Caribbean.

Winter Range: Great Blue Herons migrate singly or in small flocks, mainly in daytime. They spend winters from southern Canada southward to northern South America, and along the continental ocean coasts as far north as temperate areas of Alaska and Nova Scotia. It is rare, though not unheard of, for an occasional Great Blue Heron to successfully survive a winter in the north if it can find open water.
