What is Jacan?

Jacan is a water bird found in the southern hemisphere. In one of the main examples of reversal of the gender role of the animal, Jacana has a season of mating and reproduction very different from most other birds. Jacanas rarely wandered far from the water and lived most of their alternative lifestyle that passed lily pillows or hid underwater from predators.

Unlike many birds, a woman has almost twice the size of a male. A woman can reach a mature size of up to 23 inches (58 cm) in length, while the male is usually between 6 and 15 inches (about 15 to 39 cm) in length. Both have compact bodies, long necks and heads similar to swans. Are well adapted to life on the water; Jacana notes are long and can be spread to cover up to 8 inches (about 20 cm) wide. This allows them to walk through floating plants such as lilies pillows, leading to their nickname, Lily-Trotter.

found in parts of South America, Africa, India and Australia, this type of bird includes severaldifferent kinds. These include Bažant-Ocas, Madagascar and Wattled. Opposite the species, however, dominates women Jacanas.

During the period of reproduction, the task of female is to associate with as many different men as they can, and lay four eggs in each man's nest in the nest. Eggs are abandoned when she moves in finding her next friend, and they are hatched, fed and care for him. Women were even known to produce other nests, break eggs or kill young people, and then seize the man who watched the nest to join and lay his own eggs. Among the young people is extremely high mortality and it is assumed that this breeding with women's control in Jacana to create more eggs and ensure the success of species.

jacan can only fly short distances and more often find a walk on the surface of water of swamps or marshy areas in search of insects or along the coast and seeking no čErvy and crabs. Often you can see how they look at food under the floating leaves. When the bird threatens, it can dive underwater and stay there until the danger passes, with the tip of the beak showing enough to allow it to breathe. In sharp contrast to a woman man aggressively protects his young; Even if they can feed and travel, they will stay with them up to 70 days after hatching.
