Answer 1

Flamingos are a type of wading bird. There are four flamingo species in the Americas and two species in the Old World. Flamingos often stand on one leg, the other leg tucked beneath the body. The  reason for this behaviour is not fully understood. Recent research indicates that  standing on one leg may allow the birds to conserve more body heat, given that they spend a significant amount of time wading in cold water. However, the behaviour also takes place in warm water. As well as standing in the water, flamingos  may stamp their webbed feet in the mud to stir up food from the bottom.

Flamingos are very social birds; they live in colonies whose population can number  in the thousands. These large colonies are believed to serve three purposes for the flamingos: avoiding predators, maximizing food intake, and using scarce suitable nesting sites more efficiently. For the first six days after the chicks hatch, the adults and chicks stay in the nesting sites. At around seven to twelve days old, the chicks begin to move out of their nests and  explore their surroundings. When they are two weeks old, the chicks congregate in groups, called "microcreches", and their parents leave them alone. After a while, the microcreches merge into "creches" containing thousands of chicks. Chicks that do not stay in their creches are vulnerable to predators.
