Detailed description

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.

Lives in the form of large - up to hundreds of thousands of individuals - colonies, inhabiting the shores of ponds and lagoons. This sedentary bird - only northern populations migrating.

Flamingo unpretentious and can survive where other birds are killed - by saline and alkaline lakes. They have a thick skin on the legs, but still need to fly in fresh water to wash off the salt. There are flamingos and alpine lakes. Able to tolerate large temperature differences.

Living in Africa, the Caucasus, in Asia. Natural enemies - foxes, wolves and large birds of prey.

Compacted silt and erecting a cone-shaped nest, usually one female incubates (three - max) large white egg. The chicks are well developed and active - a few days longer leave the house. Parents feed them the bird's milk, colored in pink, because 23% of it consists of the parent blood. Provided esophageal glands and nutritionally comparable to mammalian milk. Only 2 months beak chick will grow, and he himself will be able to filter food.

Standing on one leg helps leggy birds to reduce heat loss. Apparent and difficult position does not require any effort from the birds.

Birds are in the red books of many countries, including Russia.
