This bird is a large wading bird common near the shores of open water and in wetlands over most of North and Central America as well as the West Indies and the Galápagos Islands.
From head-to-tail it measures 91–140 cm; wingspan: 167–201 cm and weight: 2–3.6 kg. The heron's stride is around 22 cm, almost in a straight line.
Herons locate their food by sight and usually swallow it whole. Herons have been known to choke on prey that is too large. This species usually breeds in colonies, in trees close to lakes or other wetlands. Great Blue Herons build a bulky stick nest, and the female lays three to six pale blue eggs. Both parents feed the young at the nest by regurgitating food.
The voice of Ardea herodias is a harsh croak. The heron is most vocal during the breeding season, but will call occasionally at any time of the year in territorial disputes or if disturbed.
