Great egret (Ardea alba)

Identification and behaviour

Adults are strikingly white with a long, tapering yellow bill and long black legs and feet. In flight they retract the neck into an S-shape and fly with slow, deliberate wing beats; their call is a low, croaking sound. Juveniles resemble adults but can show paler or duller bills during the first year.

• Length: typically around 90–104 cm from bill tip to tail.
• Key field marks: white plumage, yellow bill, black legs, S‑shaped neck in flight.
• Feeding style: stands still or slowly stalks prey, then spears with its bill.

Habitat and distribution

Great egrets use a wide range of wetland environments including marshes, mudflats, tidal shallows and flooded fields. They hunt in shallow water and along shorelines for fish, amphibians, crustaceans and insects. Populations in colder regions migrate seasonally, and in the Americas some birds winter as far south as Colombia. They are commonly associated with reedbeds, mangroves and agricultural wetlands such as rice paddies; see typical marsh habitats at wetland resources.

Reproduction and social life

Great egrets typically nest in colonies called heronries, often with other wading birds. Both parents help build the nest and care for the young. During the breeding season adults develop long ornamental plumes, sometimes called aigrettes, and perform visual displays to attract mates. Clutches usually contain several pale eggs, and chicks are fed by regurgitation.

Conservation and human interactions

Historically the great egret suffered heavy losses from plume hunting for the fashion trade in the late 19th and early 20th centuries. That decline helped spur early conservation movements and protective laws. Since protection, many populations have recovered and the species is considered widespread and relatively secure, though local threats such as habitat loss and pollution persist. Because of their visibility and dependence on healthy wetlands, great egrets are often used as indicators of wetland condition and are familiar to birdwatchers worldwide.

Notable distinctions

While similar to other large white egrets, the great egret is larger than species such as the snowy egret and is usually distinguished by its size, yellow bill and black legs. Several regional subspecies are recognized by ornithologists, reflecting variation across its broad range.
