The Jacanas are a group of tropical waders in the family Jacanidae. They are found worldwide within the tropical zone.
They 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.
The females are larger than the males; the latter, as in some other wader families like the phalaropes take responsibility for incubation, and some species (notably the Northern Jacana) are polyandrous. However, adults of both sexes look identical, as with most shorebirds.
Food is insects and other invertebrates picked from the floating vegetation or the water’s surface.
Most species are sedentary, but Pheasant-tailed Jacana migrates from the north of its range into peninsular India and southeast Asia.
