Actophilornis africanus
Family Jacanidae. A vader with long toes and long claws that enable them to walk on floating vegetation in shallow lakes, their preferred habitat.
Spotted at a river close to Malelane gate in Kruger National Park. Dry season. (http://birding.krugerpark.co.za/best-bir...)
The jacana has evolved a highly unusually polyandrous mating system, meaning that one female mates with multiple males and the male alone cares for the chicks. Such a system has evolved due to a combination of two factors: firstly, the lakes that the jacana lives on are so resource-rich that the relative energy expended by the female in producing each egg is effectively negligible. Secondly the jacana, as a bird, lays egg and eggs can be equally well incubated and cared for by a parent bird of either gender. This means that the rate-limiting factor of the jacana's breeding is the rate at which the males can raise and care for the chicks. Such a system of females forming harems of males is in direct contrast to the more usual system of leks seen in animals such as stags and grouse, where the males compete and display in order to gain harems of females.
