The Great Blue Heron is found throughout most of North America, as far north as Alaska and the southern Canadian provinces. Birds east of the Rocky Mountains are migratory and winter in Central America or northern South America. The Great Blue Heron uses its long legs to wade through shallow water, spearing fish or frogs with its long sharp bill, especially at dawn and dusk. It breeds in colonies close to lakes or other wetlands called heronry, which average between 5 and several hundred nests per colony. Adult herons, due to their size, have few natural predators, but can be taken by Bald Eagles, Great Horned Owls and Red-Tailed Hawks. Its call is a harsh croak.
The Great Blue Heron is a “Species of Concern” and is fully protected by federal and state laws under the Migratory Bird Act. – Petra Press
