Description

Great Blue Heron (Ardea herodias)

The Great Blue Heron is a wading bird in the heron family Ardeidae, common over most of North and Central America as well as the West Indies and the Galapagos Islands, except for the far north and deserts and high mountains where there is no water for it to feed in. It is an extremely rare vagrant to Europe, with records from Spain, the Azores and England.

It is the largest North American heron, with a head-to-tail length of 91-137 cm (36-54 in), a wingspan of 180 cm (71 in), and a weight of 2.2-3.6 kg (4.8-8 lbs). It is blue-gray overall, with black flight feathers, red-brown thighs, and a paired red-brown and black stripe up the flanks; the neck is rusty-gray, with black and white streaking down the front; the head is paler, with a nearly white face, and a pair of black plumes running from just above the eye to the back of the head. The feathers on the lower neck are long and plume-like; it also has plumes on the lower back at the start of the breeding season. The bill is dull yellowish, becoming orange briefly at the start of the breeding season, and the lower legs gray, also becoming orangey at the start of the breeding season. Immature birds are duller in color, with a dull blackish-gray crown, and the flank pattern only weakly defined; they have no plumes, and the bill is dull gray-yellow.

The primary food for Great Blue Heron is small fish, though they are also known to eat shellfish, insects, rodents, amphibians, reptiles, and small birds. It is generally a solitary feeder. Individuals usually forage while standing in water, but will also forage in fields or drop from the air, or a perch, into water. Herons locate their food by sight and generally swallow it whole. Herons have been known to choke on prey that is too large.
