The Little Blue HeronThe herons are long-legged freshwater and coastal birds in the Ardeidae family. There are 64 recognised species in this family. Some are called egrets or bitterns instead of herons. Within the family, all members of the genera Botaurus and Ixobrychus are referred to as bitterns, and—including the Zigzag Heron or Zigzag Bittern—are a monophyletic group within the Ardeidae. However, egrets are not a biologically distinct group from the herons, and tend to be named differently because they are mainly white and/or have decorative plumes. Although egrets have the same build as the larger herons, they tend to be smaller. The classification of the individual heron/egret species is fraught with difficulty, and there is still no clear consensus about the correct placement of many species into either of the two major genera, Ardea and Egretta. Similarly, the relationship of the genera in the family is not completely resolved. However, one species formerly considered to constitute a separate monotypic family Cochlearidae, the Boat-billed Heron, is now regarded as a member of the Ardeidae. Although herons resemble birds in some other families, such as the storks, ibises and spoonbills, they differ from these in flying with their necks retracted, not outstretched. They are also one of the bird groups that have powder down. Some members of this group nest colonially in trees; others, notably the bitterns, use reedbeds. , Egretta caerulea, is a small heronThe herons are long-legged freshwater and coastal birds in the Ardeidae family.

It breeds from the Gulf states of the USA through Central America and the Caribbean south to Peru and Uruguay. It is a resident breeder in most of its range, but some northern breeders migrate to the southeastern USA or beyond in winter. There is post-breeding dispersal to well north of the nesting range, as far as the border between the US and Canada.

It nests in colonies, often with other herons, usually on platforms of sticks in trees or shrubs. 3-7 light blue eggs are laid.

This species is about 60 cm (24 in.) long, with a 102 cm (40 in.) wingspan, and weighs 325 g (11.5 oz/0.72 lbs).

Breeding adult birds have blue-grey plumage except for the head and neck, which are purplish and have long blue filamentous plumes. The legs and feet are dark blue. Sexes are similar back.

Non-breeding adults have dark blue head and neck plumage and paler legs. Young birds are all white except for dark wing tips and have yellowish legs. They gradually acquire blue plumage as they mature.

It eats fish, frogs crustaceans, small rodents and insects.
