Description

The little blue heron (Egretta caerulea) is a small heron of the genus Egretta. It is a small, darkly colored heron with a two-toned bill. Juveniles are entirely white, bearing resemblance to the snowy egret. During the breeding season, adults develop different coloration on the head, legs, and feet.
They have a range that encompasses much of the Americas, from the United States to northern South America. Some populations are migratory. Climate change will probably cause their distribution to spread north. They can be found in both saltwater and freshwater ecosystems. Their preference for either one depends on where they live.
Nesting behaviors are documented by numerous sources. The adults build nests in trees, in colonies with other bird species. The number of eggs laid varies from place to place. The young mature quickly, requiring little attention from adults after about nineteen days of age. Both young and adults are sometimes preyed on by other species. Adults hunt fish, crabs, and other small animals. As with clutch sizes, diet can vary regionally.
The population of E. caerulea is declining. Many possible reasons for this have been proposed. Exposure to heavy metals has been found to have detrimental effects on young birds.
Males and females have the same coloration. The adults are darkly colored, with purple-maroon heads and blue bodies. During the breeding season, their heads turn dark red. They have two-toned bills, which are a light blue at the base, with black tips. Their eyes are yellow and their legs are greenish. Juveniles are almost completely white, although the upper primaries are somewhat dark in color. Like adults, their bills are two-toned. Immature birds transitioning from the juvenile to adult phase have a combination of light and dark feathers. Both sexes are about 56–74 centimetres (22–29 in), with a wingspan of 100–105 centimetres (39–41 in). They weigh about 397 grams (14.0 oz).
Little blue herons are prefer to stay still and wait when hunting, rather than chase after prey. They walk slowly and search for fish and other prey items, flying to different spots if needed. They tend to move slower than other related species, which can help distinguish them. They are not usually found in large numbers at any body of water. Occasionally, however, they will gather with other herons, especially if they have found a school of fish trapped in shallow water. They sometimes also feeds in grassy fields.
