Great Blue Heron Ardea herodias

Order: Ciconiiformes — Family: Ardeidae


Tall blue-gray bird, much larger than all the other herons except the all-white Great Egret. The white face, black crown stripe and yellowish bill further separate it from all the medium-sized herons. Two distinct, identifiable varieties also occur: The 'Great White Heron', an all white morph, found in southern Florida, resembles Great Egret but has yellowish legs and 'Wurdeman's Heron', a morph found primarily in the Florida Keys, has an all white head. The juvenile has a black crown and lacks the plumes of the breeding plumage adult.


Hoarse, croaking, 'kraank-kraank-kraank', usually heard when the bird is alarmed.




Capable of feeding on remarkably large prey items such as fish or snakes since the gullet can expand to take in very large items.


Canadian and northern United States birds move south, primarily in October, to winter from the southern U.S. to South America, returning north in April. Southern U.S. birds are non-migratory.


Coastal bays, mud flats, inland ponds, lakes, rivers, marshes and swamps.


Varied - fish, amphibians, reptiles, insects, rodents and birds.
