The red heron is a rather dainty heron with a body length of about 70 cm. It appears in a light and a dark morph . The dark blue heron is easy to confuse with the blue heron . Her plumage is also mostly blue-gray, but the neck and head are red-brown in color. However, the throat and chest are white. The light morph is almost entirely white in color. The legs and beak are gray or gray-blue in color.

Occurrence

Its habitat are the warm to subtropical swamps of southern North and North Central America . It breeds in Mexico , the southwestern United States, and some Caribbean islands such as Cuba , Jamaica, and Hispaniola .

The red heron is predominantly crepuscular. It often breeds in the company of other herons. Its nest consists of sticks and twigs and is built on trees or high bushes. In this the female lays three to seven green-blue eggs . In search of food, however, the red heron goes solitary. In the evening he walks through damp meadows and shallow waters in search of fish , amphibians , crustaceans and insects .

Etymology and history of research

The red heron was first described by Johann Friedrich Gmelin as Ardea rufescens in 1789 . He gave Louisiana as the location of the type specimen . It was not until 1817 that Thomas Ignatius Maria Forster introduced the genus Egretta for the little egret ( Egretta garzetta ). Only later was the red heron included in the genus. This name comes from the French aigrette for "heron". The specific epithet rufescens, rufescere, rufus is of Latin origin and means "reddish, become red, red". Dickeyi is dedicated to Donald Ryder Dickey (1887–1932).
