Diet

The great egret feeds alone in shallow water. It stalks prey like
frogs, crayfish, snakes, snails, and fish. When it spots its prey, it pulls its head and long neck back and then quickly stabs at the prey. On land it sometimes stalks small mammals like moles and mice. The great egret usually feeds in the early morning and evening hours.
Life Cycle

The male great egret chooses the nesting site and builds a nest platform of sticks and twigs in a tree or bush before he selects a mate. Occasionally, the great egret builds its nest on dry ground near a marsh.

The female great egret lays three to five pale green-blue eggs. The eggs take about three to four weeks to incubate. Both parents incubate the eggs and feed the chicks. The chicks fledge in about six weeks. If the nest is on the ground, the chicks walk around the nest before they fledge. Both the male and female aggressively defend the nesting territory. Great egrets nest in colonies, often with herons and ibis.
Behavior

In the early 20th century, the long feathers of the great egret were used on
ladies hats. The species was almost hunted into extinction.
