The
Snowy Egret (
Egretta thula) is a small white
heron. It is the American counterpart to the very similar Old World
Little Egret, which has established a foothold in the
Bahamas.
Adults are typically 61 centimetres (24 in) long and weigh 375 grams
(13.2 oz) They have a slim black bill and long black legs with yellow
feet. The area of the upper bill, in front of the eyes, is yellow but
turns red during the breeding season, when the adults also gain recurved
plumes on the back, making for a "shaggy" effect. The juvenile looks
similar to the adult, but the base of the bill is paler, and a green or
yellow line runs down the back of the legs.
Their breeding habitat is large inland and coastal wetlands from the lower
Great Lakes and southwestern
United States to
South America.
The breeding range in eastern North America extends along the Atlantic
and Gulf Coasts from Maine to Texas, and inland along major rivers and
lakes. They nest in colonies, often with other waders, usually on
platforms of sticks in trees or shrubs. Their flat, shallow nests are
made of sticks and lined with fine twigs and rushes. Three to four
greenish-blue, oval eggs are incubated by both adults. The young leave
the nest in 20 to 25 days and hop about on branches near the nest before
finally departing.
In warmer locations, some Snowy Egret are permanent residents; northern populations
migrate to
Central America and the
West Indies.
They may wander north after the breeding season, very rarely venturing
to western Europe—the first bird sighted in Britain wintered in
Scotland from 2001–2002.
The birds eat
fish,
crustaceans,
insects and small
reptiles.
They stalk prey in shallow water, often running or shuffling their
feet, flushing prey into view, as well "dip-fishing" by flying with
their feet just over the water. Snowy Egrets may also stand still and
wait to ambush prey, or hunt for
insects stirred up by domestic animals in open fields.
At one time, the beautiful plumes of the Snowy Egret were in great
demand by market hunters as decorations for women's hats. This reduced
the population of the species to dangerously low levels.
Now protected in the USA by law, under the
Migratory Bird Treaty Act, this bird's population has rebounded.
