![]() This species displays little sexual dimorphism. When not in breeding plumage, it is usually easily identified by its combination of three colors: black, white, and gray. In inbreeding conditions, adults have blue-gray upperparts, brown wings with chestnut coverts showing as speckles on the closed wing (visible only in flight), and whitish-gray underparts. The head is proportionately smaller than in most other large herons. ![]() It has the typical aegithognathous shape of medium-sized herons, with a long neck, straight sharp bill, stocky body, and long legs. The tricolored heron is a small heron, measuring 55-63 cm tall and weighing 0.33 to 1 kg. Like most herons it is fairly sedentary, seldom moving more than 100 km in a given year even when not breeding. Its main prey items include small fish such as cyprinids as well as frogs, insects, and crabs. The species breeds colonially in trees close to water bodies and feeds daily (diurnal), often well away from large rivers thus it appears rather sporadic at fish ponds or flooded pastures far from wetlands. The legs are dark grey or black and unfeathered to the toes. Unlike most other white egrets, it lacks any yellow in its plumage and does not show black on the upper mandible in flight. Like most typical egrets, it has a gular pouch for catching prey. It gets its name from the largely white plumage of breeding adults, especially those of the nominate subspecies. It is often seen standing on roads or on levees during the breeding season.Įxpert Tip: They nest colonially on trees close to water bodies typically mangrove swamp forests, laying 2-6 eggs each mating season. Cattle egrets exploit drier and open habitats more than other heron species. The adult cattle egret has few predators although it may be hunted by large raptors. Although it is often presumed to be named because of its association with cattle, which it accompanies in order to feed on insects flushed by them, this proposed explanation may be a folk etymology. The cattle egret is a non-migratory bird found widely in the Old World, Asia, and the Pacific region. Green Herons eat small fish, amphibians, and insects. Males can be distinguished from females by their brighter plumes during the breeding season. In-flight, distinct white patches show on the wings, which are otherwise similar to the greater yellowlegs. They have dull greenish-gray plumage all over, but this is largely concealed by their always partially retracted neck and short crest feathers unless they are breeding or displaying. Green Herons are small stocky herons with a short neck and a long thick bill with a slight downward curve. It can also be found in Florida, where it is a non-breeding bird that further north migrates to the southern United States for wintering. The green heron breeds in much of the temperate and warmer parts of the Eastern Hemisphere. The birds return to their breeding grounds in late February and early March. Large concentrations begin to leave northern areas in August, shifting to more southern locations by October and November. They have been recorded as far north as Alaska and all but central Canada in summer, though they generally do not travel far inland, being limited by warmer climate rather than food sources. ![]() Great blue herons can acclimate to all but the harshest environments. The Great Blue Heron was one of the many species originally described by Carl Linnaeus in his 18th-century work, Systema Naturae. As a member of the Ardeidae family, it is closely related to both the grey heron and night herons as well as the cocoi heron and little blue heron. The great blue heron is a wading bird of the heron family Ardeidae, common throughout North America. This conspicuous species has given rise to numerous folk tales and legends throughout its range. They frequently move about slowly stalking prey.
