Great Egret
The Great Egret is the symbol of the National Audubon Society, one of the oldest environmental organizations in North America. Audubon was founded to protect birds from being killed for their feathers.
Not all young that hatch survive the nestling period. Aggression among nestlings is common and large chicks frequently kill their smaller siblings. This behavior, known as siblicide, is not uncommon among birds such as hawks, owls, and herons, and is often a result of poor breeding conditions in a given year.
The oldest known Great Egret was 22 years, 10 months old and was banded in Ohio.
The pristinely white Great Egret gets even more dressed up for the breeding season. A patch of skin on its face turns neon green, and long plumes grow from its back. Called aigrettes, those plumes were the bane of egrets in the late nineteenth century, when such adornments were prized for ladies’ hats.
In mixed-species colonies, Great Egrets are often the first species to arrive, and their presence may induce nesting among other species.
Great Egrets fly slowly but powerfully: with just two wingbeats per second their cruising speed is around 25 miles an hour.
Though it mainly hunts while wading, the Great Egret occasionally swims to capture prey or hovers (somewhat laboriously) over the water and dips for fish.
Great Egrets live in freshwater, brackish, and marine wetlands. During the breeding season they live in colonies in trees or shrubs with other waterbirds, ranging across the southeastern states and in scattered spots throughout the rest of the U.S. and southern Canada. The colonies are located on lakes, ponds, marshes, estuaries, impoundments, and islands. Great Egrets use similar habitats for migration stopover sites and wintering grounds. They hunt in marshes, swamps, streams, rivers, ponds, lakes, impoundments, lagoons, tidal flats, canals, ditches, fish-rearing ponds, flooded farm fields, and sometimes upland habitats.
The Great Egret eats mainly small fish but also eats amphibians, reptiles, birds, small mammals and invertebrates such as crayfish, prawns, shrimp, polychaete worms, isopods, dragonflies and damselflies, whirligig beetles, giant water bugs, and grasshoppers. It hunts in belly-deep or shallower water in marine, brackish, and freshwater wetlands, alone or in groups. It wades as it searches for prey, or simply stands still to wait for prey to approach.
The male builds a nest platform from long sticks and twigs before pairing up with a female, and then both members of the pair may collaborate to complete the nest, though the male sometimes finishes it himself. The nest is up to 3 feet across and 1 foot deep. It is lined with pliable plant material that dries to form a cup structure. They don’t typically reuse nests from year to year.
Males choose the display areas, where nests are later constructed. The nest itself is up to 100 feet off the ground, often over water, usually in or near the top of a shrub or tree such as a redwood, tamarisk, live oak, eastern redcedar, yaupon holly, wax myrtle, mangrove, Australian pine, buttonwood, Brazilian pepper, black willow, or privet. Great Egrets occasionally nest on the ground or on artificial platforms.
The Great Egret walks with its neck extended and its wings held close to its body. In flight, it is graceful and buoyant, with its neck tucked back against its shoulders and its legs trailing behind. Great Egrets form monogamous pairs each breeding season, though it’s not known whether the pair bond lasts through multiple years. Early in the breeding season adults grow long plumes on their backs, which they raise in courtship displays. Males perform most of the displays, which can involve preening the wings, ducking the head, holding and shaking twigs in the bill, and stretching the neck. Nestlings compete fiercely with each other, and dominant chicks sometimes end up stabbing the youngest siblings to death. The chicks also threaten and attack intruders.
