Description

It is a small heron, 43–55 cm long, with dark slaty wings, body, and crested head, with a white throat and neck. The appearance is similar to the white-necked heron. Males (247–280 g) are heavier than females (225–242 g), but the two are similar in appearance.

Immature birds lack the crest as well as the dark colouring on the head and may look like small versions of the white-necked heron. The juveniles were once classified as a separate species.

Distribution and habitat

Its habitat mainly comprises a range of wetlands and wet grasslands.

Behaviour

Call

The call of the pied heron is a loud 'awk' or 'ohrk' in flight. Soft cooing is given around the nest. Little else is known about vocalisations.

Breeding

Breeding takes place from February to May. It nests in trees above the water, including mangroves, often colonially with other species of heron. 1–2 blue-green eggs are laid in a shallow platform of sticks.

Feeding

It feeds on insects, frogs, crabs, fish and other small aquatic animals. Insects are the most important source of food. It may feed alone or in groups of up to a thousand individuals.
