Ardea
See also: Ardea (homonymy)
Ardea is one of Héron S present in a great part of the world.
Carl von Linné described these birds as large will hérons, referring to the big size these birds, in general to 80 to 100 centimetres or sometimes more. These large will hérons are associated with the marshes where they nourish Poisson S, of Grenouille S and other watery species. The majority of the members of this race nest in large nests of branches established in the trees. The Scandinavian species such as the Large héron, the ashy Héron or the purple Héron migrate towards the south in winter, although the two first make it only if their place of wintering sees his cold stretches of water. They are powerful birds with long necks and long legs, which prédatent motionless above a not very deep water then are seized of their prey of a rapid blow of nozzle. They have a Vol regular and slow, with the retracted neck as it is characteristic of will hérons; this distinguishes them from the Cigogne S, the Grue S and the Spatule S, which them prolong their necks during the vol.
