Pink flamingo - bird, which can be called beautiful. Its plumage with shades of pink, red with white, long thin legs, very flexible and very long neck create an unusual appearance. Even a special distinguishing feature - a massive beak curved down - does not spoil the birds grace. Beak it filters food from the mud and water - movable part of the upper part unlike other flamingovyh. Unusual coloring give lipochromes - colorants from food - small crustaceans. The front toes are swimming membranes. When the danger of a bird takes off, revealing the black feathers of the wings.
