What is a flamingo?
The flamingo is a tall, pink wading bird with a thick downturned bill. They are social birds, often seen in flocks, and are known for standing on one leg, possibly to regulate body temperature or conserve energy. Their nests are made of muddy clay, where they incubate one or two chalky-white eggs.
Flamingos feed by stirring up organic matter in shallow waters and filtering food with comblike structures in their bills. Their diet includes algae, diatoms, and small invertebrates, which contain carotenoid pigments that give them their pink color. There are six species of flamingos found in various parts of the world.

Where do flamingos live?
Flamingos are wading birds with pink feathers that live in various places around the world. The greater flamingo breeds on the coasts of the Atlantic Ocean and Gulf of Mexico in tropical and subtropical America. The Chilean flamingo lives primarily inland. Two smaller species live high in the Andes Mountains of South America: the Andean flamingo and the puna flamingo. The lesser flamingo inhabits the lake district of East Africa and parts of South Africa, Madagascar, and India. Because habitat and food sources vary from place to place and season to season, the birds’ colors also vary.

What do flamingos eat?
Flamingos are wading birds that feed by stirring up shallow water with their webbed feet and using their bills to strain food. Their diet consists of various food types, such as minute mollusks, diatoms, algae, blue-green algae, and crustaceans. They have a highly specialized method for feeding that involves hairlike plates inside their mandibles that act as filters. The pink color that flamingos are known for comes from carotenoid pigments in the foods they eat. The color of a flamingo can vary based on habitat and food sources.

Why are flamingos pink?
Flamingos' bright pink color isn't hereditary; they're born dull gray. Their vibrant hue comes from beta-carotene, a red-orange pigment in the algae, brine fly larvae, and brine shrimp they eat in wetlands.
Enzymes break down carotenoids into pigments, absorbed by fats in the liver, and then deposited in the feathers and skin. The flamingo diet, rich in carotenoids, effortlessly colors them. Color variations occur among the six flamingo species due to differing habitats and food sources, resulting in shades from dark to bright pink, orange, red, or even white.

How do flamingos care for their young?
Flamingo parents build cone-shaped nests from mud in shallow lagoons for their eggs. Both parents participate in the month-long incubation of typically one or two chalky-white eggs.
After hatching, the downy white young leave the nest within a few days. They are fed by both parents, who regurgitate partly digested food. The young flamingos are grey and have red bills and legs that turn black in a few days. After a few days, flamingo chicks move around the colony but are still fed by their parents. The parents feed their young this way until their filtering system is developed at around two months old.

Flamingo, (order Phoenicopteriformes), any of six species of tall, pink wading birds with thick downturned bills. Flamingos have slender legs, long, graceful necks, large wings, and short tails. They range from about 90 to 150 cm (3 to 5 feet) tall.
Flamingos are highly gregarious birds. Flocks numbering in the hundreds may be seen in long, curving flight formations and in wading groups along the shore. On some of East Africa’s large lakes, more than a million lesser flamingos (Phoeniconaias minor) gather during the breeding season. In flight, flamingos present a striking and beautiful sight, with legs and neck stretched out straight, looking like white and rosy crosses with black arms. No less interesting is the flock at rest, with their long necks twisted or coiled upon the body in any conceivable position. Flamingos are often seen standing on one leg. Various reasons for this habit have been suggested, such as regulation of body temperature, conservation of energy, or merely to dry out the legs.
The nest is a truncated cone of muddy clay piled up a few inches in a shallow lagoon; both parents share the monthlong incubation of the one or two chalky-white eggs that are laid in the hollow of the cone. Downy white young leave the nest in two or three days and are fed by regurgitation of partly digested food by the adults. Subadults are whitish, acquiring the pink plumage with age.

To feed, flamingos tramp the shallows, head down and bill underwater, stirring up organic matter with their webbed feet. They eat various types of food, including diatoms, algae, blue-green algae, and invertebrates such as minute mollusks and crustaceans. While the head swings from side to side, food is strained from the muddy water with small comblike structures inside the bill. The bird’s pink colour comes from its food, which contains carotenoid pigments. The diet of flamingos kept in zoos is sometimes supplemented with food colouring to keep their plumage from fading.
The greater flamingo (Phoenicopterus roseus) breeds in large colonies on the coasts of the Atlantic Ocean and Gulf of Mexico in tropical and subtropical America. There are two subspecies of the greater flamingo: the Caribbean flamingo (P. ruber ruber) and the Old World flamingo (P. ruber roseus) of Africa and southern Europe and Asia. The Chilean flamingo (Phoenicopterus chilensis) is primarily an inland species. Two smaller species that live high in the Andes Mountains of South America are the Andean flamingo (Phoenicoparrus andinus) and the puna, or James’s, flamingo (Phoenicoparrus jamesi). The former has a pink band on each of its yellow legs, and the latter was thought extinct until a remote population was discovered in 1956.
The lesser flamingo (Phoeniconaias minor), which inhabits the lake district of East Africa and parts of South Africa, Madagascar, and India, is the most abundant. It is also the smallest and the deepest in colour. In ancient Rome, flamingo tongues were eaten as a rare delicacy.
Flamingos constitute the family Phoenicopteridae, which is the only family in the order Phoenicopteriformes. They are sometimes classified in the order Ciconiiformes (herons and storks) but also show similarities to anseriforms (ducks and geese), charadriiforms (shorebirds), and pelecaniforms (pelicans and cormorants).
