Description

•The Great Blue Heron belongs to a large family that includes herons, egrets, and bitterns. This world-wide family has about 60 species. The Great White Heron of Florida is a local color variation of the Great Blue and belongs to the same species.

•The Great Blue Heron’s long legs allow it to hunt in deeper water than most other herons and egrets.

•Herons have special patches of powder down feathers, which they rake with a foot, causing the powder to fall on fish it has caught. The powder causes the fish slime and oil to clump up so that the herons then can simply brush it off with a foot. Herons also rub the powder especially on the underside of their bodies to repel swamp slime and oils.
•The Great Blue Heron can swallow a fish many times wider than its narrow neck.

•Herons look for food anytime there is enough light. Studies suggest that cloudy weather is ideal for the birds to look for fish. Herons don’t just eat fish, however. They eat a wide variety of prey, including frogs, salamanders, turtles, snakes, insects, rodents, and small birds.
•In catching fish, the Great Blue Heron grabs smaller fish between the two mandibles of its bill; with a quick strike it stabs the larger fish.

•In the Pacific Northwest, eelgrass beds are important foraging sites for the Great Blue Heron.
•Herons nest in colonies. One of the largest colonies in Washington is located in Renton; last year there were approximately 135 active nests there.

•Great Blue Herons often reuse a nest, adding sticks to it each year. The male brings sticks and the female works them into the nest. Older nests can be recognized by their large size.

•Great Blue Herons lay from three to seven eggs, but the usual number is four.

•Young Great Blue Herons are semialtrical: they emerge from the eggs with a downy coat and their eyes open, but they aren’t able to move about and must be fed by their parents. They grow to adult size in about six weeks.

•Heron chicks are often aggressive toward each other, and some are pushed out of the nest.

•Adult Great Blue Herons have no natural predators, although bobcats and coyotes occasionally kill one while feeding on the ground. Young herons in the nest are often killed by crows, ravens, gulls, hawks, eagles, and raccoons. Eagles have been known to cause entire heron colonies to fail.

•It is dangerous to handle a Great Blue Heron. It can strike quickly; its bill is strong and very sharp and can cause serious injury.
