Bronze-winged Jacana


The Bronze-winged Jacana, Metopidius indicus, is a jacana. It is the only member of the genus Metopidius. The jacanas are a group of waders in the family Charadriidae, which are identifiable by their huge feet and claws which enable them to walk on floating vegetation in the shallow lakes that are their preferred habitat. They are found worldwide within the tropical zone.
The Bronze-winged Jacana breeds in India and southeast Asia. It is sedentary apart from seasonal dispersion. It lays four black-marked brown eggs in a floating nest. The males, as in some other wader families like the phalaropes, take responsibility for incubation.
These are conspicuous and unmistakable birds. They are 29cm long, but the females are larger than the males. They are mainly black, although the inner wings are very dark brown and the tail is red. There is a striking white eyestripe. The yellow bill extends up as a red coot-like head shield, and the legs and very long toes are grey.
Measurements (from Rasmussen and Anderton, 2005) Length 280-310 mm Wing 150-197 mm (males 150-180mm , females 167-187 mm) Bill from tip to top of frontal shield 34-46 mm (adults) 32-38 (juveniles) Tarsus 61-76 mm Tail 40-52 mm.
