Description

Blacksmith lapwings are very boldly patterned in black, grey and white, possibly warning colours to predators. It is one of five lapwing species (two African, one Asian and two Neotropical) that share the characteristics of red eyes and a bold pied plumage, with a carpal (wing) spur adorning the wrist joint; a sharp black protrusion which they use to aggressively defend their young from potential threats, through persistent aerial dives typically targeting the head. The portions of the bird's body bare to plumage average a black coloration for the bill, and either a black or white-grey dappling on the legs. Females average larger and heavier but the sexes are generally alike.

Habitat and numbers

The blacksmith lapwing occurs in association with wetlands of all sizes. Even very small damp areas caused by a spilling water trough can attract them. In South Africa they are most numerous in the mesic grassland region, less so in higher-rainfall grasslands. Like the crowned lapwing, this species may leave Zambia and Zimbabwe in years of high rainfall and return in dry years. It avoids mountains of any type. Blacksmith lapwings expanded their range in the 20th century into areas where dams were built and where

Ecology

During the breeding season, the species often reacts aggressively to other lapwings or African jacanas that may enter its wetland habitat. Nests are shallow depressions on bare ground or short grass, close to water, and tend to be spaced at least 400 m apart. The blacksmith lapwing breeds in spring, but its choice of nesting site and timing may be opportunistic. The young separate gradually from their parents and do not return to natal areas afterwards. This lapwing feeds on aquatic and terrestrial invertebrates.
