Great Blue Heron

The Great Blue Heron is found throughout most of North America, as far north as Alaska and the southern Canadian provinces. The range extends south through Florida, Mexico and the Caribbean to South America. Birds east of the Rocky Mountains in the northern part of their range are migratory and winter in Central America or northern South America. From the southern United States southwards, and on the Pacific coast, they are year-round residents. However their hardiness is such that individuals often remain through cold northern winters, as well.

The Great Blue Heron can adapt to almost any wetland habitat in its range. They may be found in numbers in fresh and saltwater marshes, mangrove swamps, flooded meadows, lake edges, or shorelines. They are quite adaptable and may be seen in heavily developed areas as long as they hold bodies of water bearing fish. Great Blue Herons rarely venture far from bodies of water but are occasionally seen flying over upland areas. They usually nest in trees or bushes near water's edge, often on island (which minimizes the potential for predation) or partially isolated spots.

It has been recorded as a vagrant in England, Greenland, Hawaii, and the Azores.
