With an estimated 2,000 pairs, the Reddish
Egret is North America’s rarest heron. Before 1900 it
was nearly extirpated from the U.S. by plume hunters. A present
as a resident in the U.S., it is virtually limited to coastal
lagoons in the Gulf States, with the greatest number, some
1,500 pairs, in Texas. In Florida, where it was unreported
from 1927 to 1937, there are now some 350-400 pairs. It breeds
also in the West Indies and the Bahamas, and in scattered
localities on both coasts of Mexico. Some birds withdraw from
the breeding range as far as Venezuela.
Since 1970 there have been increased sightings
of the bird in Central and South America which may reflect
increasing numbers but which also could be the result of more
observers. The bird has a dark morph, predominating in the
U.S. and Mexico, and a white morph, more common in the Bahamas
and Greater Antilles. Nesting habitat in Florida and the West
Indies are mangrove keys and dredge islands in mangroves but
in Texas it nests on natural and artificial islands in low
vegetation, often in mixed colonies with other herons. It
forages on shallow flats, ponds and lagoons near the coast,
often in hypersaline flats and lagoons. Its food is primarily
small fish.
Coastal development and consequent loss
of habitat is the most important threat to the species.
