Taxonomy

The species was originally described by ornithologist John Gould in 1845. Recent taxonomists put this species in the genus Egretta. There are no recognised subspecies.[4]
Description
It is a small heron, 43–55 cm (17–22 in) long, with dark slaty wings, body, and crested head, with a white throat and neck. The appearance is similar to the white-necked heron.[3] Males (247–280 g (8.7–9.9 oz)) are heavier than females (225–242 g (7.9–8.5 oz)), but the two are similar in appearance.[5]
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.[5]
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.[3] Soft cooing is given around the nest.[5] Little else is known about vocalisations.[5]
Breeding
Breeding takes place from February to May.[3] 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.[3]
Feeding
It feeds on insects, frogs, crabs, fish and other small aquatic animals. Insects are the most important source of food.[5] It may feed alone or in groups of up to a thousand individuals.[5]
