It is mainly resident, but some west African birds move further north in the rainy season.

This species usually breeds in the wet season in colonies in trees, reedbeds or cliffs.

It often feeds in shallow water, spearing fish or frogs with its long, sharp bill.

It also hunts well away from water, taking large insects, small mammals, and birds.

This is characteristic of herons and bitterns, and distinguishes them from storks, cranes, and spoonbills, which extend their necks.
