- Egretta rufescens
Dichromanassa rufescens
Identification
Length: 26-31¾" (66–81 cm). Wingspan: 46" (117cm), Weight: 1lb (450gm)
A large polymorphic wading bird with long, flexible neck and long legs characteristic of the family. Most birds are the dark morph, and are easy to identify with their reddish heads and fronts, and reddish-gray rear half. Immatures are greyish-brown, pale below with reddish tinge to neck faint or absent; bill mostly black.
Variations
The Pacific coast subspecies has paler head and neck than eastern birds. In the Gulf of Mexico there is a small population (no more than 7%) of the white morph, more common further south in the Caribbean. It can be difficult to distinguish from other egrets: note the completely dark legs, dark lores , and long dark heavy bill that however is conspicuously two-toned in breeding season, pink with dark tip.
Distribution
North America, Central America, and northern South America as well as in the Caribbean.
In North America breeds on the Gulf Coast of the USA, Mexico and on the Pacific Coast of Mexico; outside breeding season spreads to California (where it may also breed) as well as north along the Atlantic coast.
In Central America is found in summer along the coast of Yucatan in Mexico and Honduras and on the Pacific coast down to Costa Rica. More widespread outside of breeding season.
In northern South America is found on the caribbean coast of Colombia and Venezuela.
In the Caribbean, it is expected to be breeding in Bahamas and Cuba, with recent summer records also from Hispaniola and Puerto Rico. Extirpated as breeding bird in Jamaica, but occurs there outside of breeding season.
Vagrant in Panama.
Taxonomy
Subspecies
Two subspecies are recognized:[1]
- E.r. rufescens - Gulf Coast of US, West Indies, winters to northwest South America
- E.r. dickeyi - southern half of Baja California, wintering into Guatemala and El Salvador: paler head and neck; no white morph.
Habitat
Mainly coastal, found on tidal mudflats and estuaries, rarely inland.
Behaviour
Breeding
They nest on coastal islands almost year round in Florida, with peaks in November to January and February to May; March to June in Texas; and summer in Baja California. The nest is quite flat and large for the size of the bird. It is composed of dry sticks, interspersed with grass and leaves. They form colonies alongside other herons, spoonbills or cormorants. On arid islands they nest on low shrubs, cactus or on ground but in mangroves they use trees or high bushes. Clutch is typically 3-4 eggs; incubation period is 25-26 days. Chicks of white morph have white down, while those of dark morph have smoky grey down with greyish cinnamon head and neck. The young fledge in about 45 days.
Diet
Forages in shallow coastal areas and estuaries for small fish, usually no more than 10 cm/4 inch long. Usually solitary, they move quickly compared to other wading birds. They have a variety of feeding techniques either holding or flicking their wings open when feeding, presumably to either cast shadow and attracting fish or to scare the fish into movement which makes them easier to see.
Vocalisations
Usually silent. Most common call is a throaty awwwwh or AWWH-uhh.
