The tall, pink flamingos are an instantly recognizable group of birds, which have been known from earliest times and often celebrated in popular stories. They belong to one of the bird families, dating back at least 30 millions years, when their range extended to North America and Australia.
All species have a long, slender neck and tall, spindy legs, a fairly small body, and large, specially adopted, drooping bill. Their plumage varies between pale and deep rose-pink, with crimson and black wings.
Flamingos are extremely sociable and usually occur in large flocks. At times, they form the biggest concentration of non-passerine birds: on occasions, more than a million gather at feeding sites. The birds forage by wading knee-deep at the edges of alkaline or saline lakes and lagoons.
They turn their head upside down and sweep the bill through the water, sucking in mouthfuls. As they squeeze out excess water with their tongue, comb like structures called lamellae trap tiny particles of food.
Flamingos breed in large colonies at the edge of lakes or on island. In East Africa, the only reliable breeding site is Lake Natron in Northern Tanzania. The nest is circular mound of mud baked hard by the sun, into which the female lays on white egg. The chicks look like fluffy duck-lings on hatching, and are fed on a milky mash regurgitated by their parents.
After a few days, they join a large group of youngsters within the colony, but continue to be fed by their parents for about 10 weeks longer, until they can fly and become fully independent.
