Ardeidae

The species in the Ardeidae which are named as bitterns tend to be the shorter necked, often more secretive members of this family. The herons are the longer-necked species.

The members of this family are all primarily associated with wetlands, and predate fish, frogs and other aquatic species. Some, like the Cattle Egret, also take large insects, and are less tied to watery environments.

A variety of techniques are used for hunting, and these are dealt with in the species' accounts.

Some members of this group nest colonially in trees, others, notably the bitterns, use reedbeds.
