Jacanas have a highly unusual mating system. In all species of jacana, the female is larger and more aggressive than the male, and is sometimes more colourful. She will control a large territory that encompasses the territories of one to four males, and defend them from other females. These males make up her harem, and she will copulate with all of them during the breeding season. One particular male will receive most of her attention; this male will be the one chosen to incubate the eggs and care for the chicks, and is called the receiver. If the receiver feels that he has not received enough sexual attention from the female, and thus may not be the father of enough of the eggs, he may destroy the nest and eggs. In turn, however, if a female finds one of her males incubating a nest from a strange female, she will destroy it.
