American Bittern
Botaurus lentiginosus
Bird · State-listed as a species of concern or endangered in Iowa due to the ongoing loss and degradation of wetland habitats.
Summary
The American Bittern is a secretive, medium-sized marsh bird known for its distinct, booming call during the breeding season. It relies heavily on cryptic plumage to blend into tall wetland vegetation. This species is an elusive resident and migrant across Iowa's suitable wetland habitats.
Identification tips
Features a stout body, brownish-buff streaked plumage, and a dark streak running down the sides of its neck. When alarmed, it freezes and points its bill straight up to mimic swaying reeds. It has a shorter neck and stockier build than other similar herons.
Habitat
Found primarily in freshwater marshes, shallow wetlands, and dense emergent vegetation like cattails and reeds. It requires secluded, undisturbed wetland areas with thick cover for foraging and nesting.
Similar species
