They appear stocky with a short neck, short thick bill and buff-brown back. In summer, adults have long neck feather. They are widespread and common but can be easily missed when they stalk prey at the edge of small water-bodies or even when they roost close to human habitations. They are however distinctive when put to flight, the bright white wings flashing in contrast to the cryptic streaked olive and brown colours of the body. The camouflage is so excellent that they will often allow humans to approach very close before taking to flight, and this has resulted in folk names and beliefs that the birds are short-sighted or blind. They are usually solitary foragers but numbers of them may sometimes feed in close proximity during the dry seasons when small wetlands have a high concentration of prey. They are semi-colonial breeders. They may also forage at garbage heaps. During dry seasons, they sometimes take to foraging on well watered lawns or even dry grassland. From Wikipedia.
