The least bittern is the smallest heron in the Americas, adept at moving through dense reeds by gripping stems with long toes. It often freezes with bill pointed upward to blend with marsh vegetation. When threatened, it can compress its body to slip between cattails and sedges. Despite being widespread, it is hard to see due to its secretive habits.

Social Behavior
Typically solitary or in loose pairs during breeding. Nests are shallow platforms hidden in dense emergent plants; both sexes incubate and feed the young. Clutch sizes are moderate, and pairs may raise one or more broods depending on conditions.
Migratory Pattern
Partial migrant
Song Description
The song is a soft, repetitive cooing or chuckling series, often described as coo-coo-coo from within dense reeds. Calls include quiet clucks and ticks given at dawn and dusk. Vocalizations carry poorly, adding to its elusiveness.
