Wattled Jacana, Pantanal, Brazil
Jacanas are odd birds to begin with. For one, they have enormous feet which enable them to walk on floating vegetation, like lily pads, without sinking. The females of the species are polyandrous — meaning they will take two or more (usually 4) mates at the same time. The males will incubate the eggs, while the females defend their various nests. But perhaps the most curious thing about certain jacanas, including this wattled jacana from Brazil, are the wing spurs. It remains uncertain as to what exactly the purpose of the spurs is.
