Taxonomy/Description
Snowy Egrets are in the family Ardeidae which consists
of herons. Snowy Egrets are about 24 inches (61cm) in size.
They have a white body with yellow facial skin. Snowy
Egrets have wispy plumes on the back of their neck
during the breeding season. They are wading birds which
means they have long legs and hold their neck in an "S"
shape when flying. Their legs and bill are black while
their feet are yellow, which distinguishes them from the
Great Egret which has a yellow bill and black legs and
feet. Both male and female Snowy Egrets look
similar.
Habitat/Diet
Snowy Egrets tend to like a variety
of wetlands of fresh, salt and brackish water. They are very common
both
along coasts and further inland. The wintering grounds of Snowy
Egrets include most of Mexico and Central America, West Indies and
Florida. They can been seen breeding in the West Indies, Florida,
and Oregon Coast. They are considered to be vagrants in Western New
York.
Snowy Egrets usually feed on smaller aquatic and
terrestrial insects and vertebrates. Snowy Egrets show
an active pursuit of prey in comparison to most other Herons and
Egrets. They use their yellow feet to stir mud and flush prey while
they are wading in the water. They can be seen feeding following the
Glossy Ibis as it stirs up food for the Snowy Egret to capture.

Behavior/Reproduction
Snowy Egrets are very ground-oriented when it comes
to courtship, nesting and feeding. At dusk, Snowy Egrets
gather from surrounding areas to form communal roosts.
Post-breeding dispersal is very common among Snowy
Egrets. After the young hatch, they accompany the adults
on long journeys. Many heron species rob other species
in order to obtain more food. Snowy Egrets steal a very
high percentage of their food items because they are highly
aggressive and additionally will do this even when food is not
limited.

Snowy Egrets have a monogamous mating
system and usually have one brood per year. They nest in colonies
and many times in mixed colonies that contain more than one species.
The male will collect nest material and the female will build it.
The female will lay 3-5 light bluish-green eggs and both sexes will
take turns incubating for 20-24 days. Snowy Egret young are semialtricial which means they are immobile, downy with their eyes
open and are fed. Both sexes will care for the young which are ready
to leave the nest about 30 days after hatching.
Where to see
them
in WNY
As a result of these birds being vagrants to this
area there is rarely more than a few individuals. If they are found
in WNY they will be seen in wetlands and large bodies of water.
Historically this species has been found near Buffalo near the water
front and more recently in Iroquois NWR.
