Medium-length, sharp, black bill with olive-gray base. Long, broad wings. Short, square tail. Medium, green-yellow legs and feet. Feeds on reptiles, small fish, and insects.

Breeding and Nesting

Rufous Night-Heron: Two to five white-green eggs are laid in an untidy platform nest constructed with sticks and twigs. The nest is built in a tree or bush over a body of water. In some areas, it also nests on the ground, under rocky overhangs, or in caves. The eggs are incubated by both sexes for 21 days. This species nests in colonies.

Foraging and Feeding

Rufous Night-Heron: Feeds on reptiles, amphibians, small fish, and insects. This heron species mostly forages at night in shallow water. It catches prey with a quick thrust of its bill after waiting for food items to appear at the edge of or near the surface of the water.

Vocalization

Rufous Night-Heron: In flight, emits loud "wock" or "quok." Also produces "rok" when alarmed and "wak-wak-wak-wak" while roosting.
