Northern jacana
The northern jacana or northern jaçana (''Jacana spinosa'') is a wader which is a resident breeder from coastal Mexico to western Panama, and on Cuba, Jamaica and Hispaniola. It sometimes breeds in Texas, USA, and has also been recorded on several occasions as a vagrant in Arizona (). The jacanas are a group of wetland birds, 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. In Jamaica this bird is also known as the 'Jesus bird', as it appears to walk on water.〔(Great Adventures, Saint Elizabeth, Jamaica )〕 Jacana is Linnæus' scientific Latin spelling of the Brazilian Portuguese ''jaçanã,'' pronounced (:ʒasaˈnɐ̃), from the Tupi name of the bird. See jacana for pronunciations.
==Description==
The northern jacana has a dark brown body with a black head and neck. In addition its bill has yellow patches and its forehead has a wattle.〔Janzen, D.H., Ed. (1983). Costa Rican Natural History. Chicago and London, U Chicago Press.〕 Its bill has a white base. When a jacana is in flight, its yellow primary and secondary feathers are visible. Juveniles have a white supercilium and white lores. The female jacana is around twice as big as the male, averaging (145.4g) compared to (86.9g).〔Jenni, D.A. and Collier, G. (1972). "Polyandry in the American Jacana (Jacana spinosa)."
