Little Blue Heron -- South Dakota Birds

Little Blue Heron

Egretta caerulea

A smaller heron that is normally found in the southeastern United States.  Little Blue Herons are generally quite wary and difficult to approach as they wade in shallow marshes and sloughs.  Immatures in their all-white plumage, as with the bird shown to the right, are quite similar to Snowy Egrets.  Mature birds are dark bluish gray overall.  Little Blue Herons have been expanding their range to the north in recent decades, and are becoming more commonly seen in the upper Great Plains.

Habitat: Marshes and sloughs, margins of shallow ponds and lakes with emergent vegetation. 

Diet: Mostly fish and crustaceans, also frogs, tadpoles, insects, snakes, lizards, and small rodents.

Breeding: Rare breeder in South Dakota.

Song: Aah-oo-ah-ah-ah by male during courtship.  

Migrations: Summers in the Southeastern U.S., and in scattered locations elsewhere in the U.S.  Winters along Gulf Coast, Florida, Mexico, Central America, and South America.

Similar Species: Tricolored Heron.  Immatures similar to Snowy Egret, Great Egret, and Cattle Egret.  See Identification Tips page for differentiating between the white Egrets and the immature Little Blue Heron.

Status: Has been increasing range northward and expanding in population.
