American flamingos are waders and good swimmers. They congregate in large flocks. This bent bill is an adaptation for feeding, and designed so that the bent portion is parallel with the bottom of the pond, lake or flats in which they are feeding. The legs of the American flamingo are long, which enables them to wade into much deeper water than most other birds. Webbed feet support them on soft mud.
Flamingos frequently stand on one leg.
Being able to curl the leg under the body, American flamingo keeps the foot warm and conserves body heat. Flamingo stand on one leg in both cool and warm environments. American flamingos reach sexual maturity several years after birth. Breeding can occur in any season, and a flamingo may breed twice in a year. Breeding and nest building may depend on rainfall and its effect on food supply.
