[edit] Similar Species

Smaller than Western Reef Heron and can be distiguished from that and a melanistic Little Egret in flight by faster wing beats and feeding method (see Behaviour)

[edit] Distribution

Sub-Saharan Africa: breeds widely but discontinuously from Senegal to Sudan and south, mainly through the eastern half of the continent, to South Africa.

Probably dispersive rather than migratory, perhaps nomadic in response to rains in some areas.

Monotypic[1]

[edit] Habitat

Lake margins and riverbanks, tidal creeks, rice fields and flooded grasslands.
