Region
Amazon Basin and Guianas
Typical Environment
Occurs in lowland tropical swamps and seasonally flooded forests (várzea and igapó) across northern South America, including the Guianas and much of the Amazon Basin. It favors dense understory along slow streams, oxbow lakes, and backwaters with overhanging roots and fallen logs. Often stays close to shaded margins and thickets where cover is abundant. Rarely ventures into open water or exposed shorelines, preferring concealed foraging sites.

The zigzag heron is the sole member of the genus Zebrilus and is one of the smallest herons in the Americas. It is extremely secretive, spending much of its time in dense flooded forest where it is more often heard than seen. Its finely barred plumage creates a zigzag pattern that provides excellent camouflage among roots and reed tangles. Most detections come at dusk or night when it gives distinctive frog-like calls.

Social Behavior
Typically solitary or in pairs, staying concealed in thick vegetation near water. Nests are small platforms placed low over water or in dense thickets. Clutches are usually small, and both parents are thought to share incubation and chick care. Territorial defense is mostly vocal and occurs at dusk or night.

Resident
Song Description
Gives a series of low, frog-like hoots and grunts, often in rhythmic sequences at dusk and during the night. Calls carry through flooded forest and can be mistaken for amphibians. Daytime vocalizations are infrequent.
