not on bird list, but hes real

|You wont find the name
Louisiana Heron in any modern birding field guide.
Thats because, in its infinite wisdom, the American
Ornithological Union changed its name to Tricolored Heron
over 40 years ago. Thats a real shame because the
bird was known as the Louisiana Heron for at least 175
years prior to that time!
Today, the Tricolored Herons common name is based, presumably on its combination of blue, brown, and white colors of various hues. Theoretically, common names should be descriptive and not geographically limiting accounting for the name. But, both the Great Blue Heron and the diminutive Green Heron share similar color patterns with the Tricolored Heron although its intermediate size alone permits easy separation of the three species.
In the 1800s, John James Audubon described the Louisiana Heron thusly Delicate in form, beautiful in plumage, and graceful in its movements, I never see this interesting Heron, without calling it the Lady of the Waters.... Audubon wrote hundreds of words about this bird but most current accounts are very short! These herons have conspicuously long, slender bills as well as long graceful necks.
Both sexes of Tricolored Herons resemble each other but there are two color phases, breeding and non-breeding. During the breeding season the birds have blue bills with black tips and pink legs. Legs turn yellow during the non-breeding season. Bodies have dark bluish gray color during both breeding and non-breeding seasons. Bellies and underwings are contrasting white. There are white lines on the bottoms of their necks. Breeding birds have distinct white crests.
Juvenile Tricolored Herons resemble adults in color.
However, there is much rufous and reddish brown color in
their necks, shoulder areas, and wings. Legs and bills
are yellow and backs are bluish gray and bellies are
Tricolored Herons tend to be solitary feeders. They
typically stand in shallow water searching for food and,
once prey is spotted, run toward it with wings open.
Sometimes they will slowly stalk prey. Unlike other
medium-sized herons and egrets, Tricolored Herons will
wade well into water up to their breasts in search of
Tricolored Herons are most commonly found along the coasts of the Gulf of Mexico and the Atlantic Ocean. Some do nest well inland from the coast and there seems to have been a general inland movement of nesting birds over the past half century. Post breeding dispersal in the summer accounts for occasional reports of Tricolored Herons well into the USAs interior.
