Description:
The tricolored heron
is a medium sized wading bird that grows to a height of approximately 22 inches,
with a wingspan of 38 inches. The sexes are similar in appearance, with overall body
color gray along the neck, back and wings; and white along the foreneck and
much of the ventral area. The legs are greenish or yellow in color, and the
black-tipped bill can range from shades of blue to yellow.
Habitat:
The tricolored herons share habitat with other species of wading birds, particularly the
great blue heron, the little blue heron, and the snowy egret, but show a
preference for mangrove habitats and coastal marshes over inland marshes and
sloughs. They also seem to prefer small pools over larger bodies of
water. When inhabiting freshwater areas such as Lake Okeechobee,
Florida, tricolored herons are particularly attracted to areas where Hydrilla and
lotus (Nelumbo lutea) grow.
Similar Species:
Juvenile little blue herons in the process of molting may show dark blue
wings and a white belly, but would also have a scattering of white feathers
on the back and neck, which does not occur in tricolored herons.
Range:
Tricolored herons occur along the Atlantic coast from Massachusetts south through Florida, the
Gulf of Mexico and much of South America.

While other heron and egret species
such as the great blue heron and the little blue heron will alter their
diets in response to changes in prey concentration and habitat conditions, tricolored herons and snowy egrets do not. Rather, they change their
feeding strategies in order to continue to capture the prey they prefer.
