Herons, Egrets, and Bitterns
Ardea alba
The Great Egret is a large, elegant wading bird with brilliant white plumage, a long, S-shaped neck, and a commanding presence in wetlands. This widely distributed species is a familiar sight across much of the world, often seen patiently stalking prey in shallow waters. Its striking appearance and graceful movements make it a captivating subject for birdwatchers and nature enthusiasts alike.

Individuals and populations vary.
01 / The telltale details
Start with shape and behavior. Then look for the smaller details.
Entirely white feathers, giving it a pristine appearance.
Typically a long, sharp yellow bill; however, some subspecies in the Old World may have a dark bill during breeding season.
Long, dark gray to black legs and feet.
During breeding season, adults develop long, delicate, lacy plumes on their backs that extend past the tail.
02 / A place in the world
Great Egrets inhabit a variety of aquatic environments, including freshwater and saltwater marshes, ponds, lakes, rivers, and coastal areas. They prefer shallow water for foraging and often nest in trees or shrubs near these water sources.
This species has a vast global distribution, found across tropical and warmer temperate regions of the world, including Asia, Africa, the Americas (from southern Canada to Tierra del Fuego), and southern Europe. It has also expanded its range into more northern European areas.
Great Egrets can be resident in warmer climates, but northern populations are migratory, moving south for the winter. Extensive post-breeding dispersal is common, with individuals sometimes wandering far north before migrating to their wintering grounds.
03 / Listen a little closer
Great Egrets are not typically vocal, but they produce a low, hoarse croak when disturbed. At breeding colonies, they may emit louder croaking sounds and higher-pitched squawks.
04 / The life behind the feathers
Their diet primarily consists of fish, frogs, and other small aquatic animals. They also consume crustaceans, snakes, salamanders, and various insects. Occasionally, they may prey on small mammals like mice.
Great Egrets are patient and precise hunters. They typically wade slowly or stand motionless in shallow water, waiting for unsuspecting prey. With a rapid thrust of their long neck and bill, they spear their catch.
Nests are bulky platforms made of sticks and twigs, often built in trees or shrubs, usually in colonies with other water birds. Both parents incubate the 3-5 pale greenish-blue eggs for about 23-30 days and care for the chicks until they fledge in approximately six weeks.
These birds are generally solitary foragers but gather in communal roosts at dusk. During the breeding season, males perform elaborate courtship displays, showcasing their plumes to attract females. They are territorial and can be aggressive, especially when defending their nesting sites.
One more reason to pay attention
The Great Egret is the symbol of the National Audubon Society, an organization founded to protect birds from being hunted for their feathers.
In the late 19th century, Great Egrets were hunted almost to extinction for their elegant plumes, which were highly prized for ladies' hats.
Aggression among nestlings is common, and larger chicks may kill their smaller siblings, a behavior known as siblicide.
05 / An eye for the difference
Snowy Egrets are smaller, have a black bill with a yellow lore (patch of skin between the bill and eye), and yellow feet.
