Herons are wading birds in the Ardeidae family. There are so far 64 species in this family. Another term for herons is “bitterns”. Egrets are similar to Herons, and tend to named differently because of their white coloring and decorative plumes. The Great Blue Heron is blue-gray overall, with black accent feathers.Herons look similar to some other birds, such as the storks, ibises and spoonbills, but they differ from these in flying with their necks pulled back. Most herons nest colonially in trees. The members of this family are mostly associated with wetlands, and prey on fish, frogs, invertebrates, rabbits, and snakes.
