Their pink plumage comes from their diets.

Flamingos are brightly colored birds that live in tropical areas around the world. They are known for their pink plumage, long, slender legs, and downward-bending beaks. The name flamingo comes from the Portuguese or Spanish word “flamengo,” which means flame-colored. The six species of flamingo each sport its own shade of pink. Overall, the birds are not in danger of extinction, though the population of some species is considered near threatened.

Facts on Flamingos

Flamingos are omnivores (animals that eat both meat and plant matter) that live in different tropical parts of the world. The Andean flamingo can be found in southern Peru, western Bolivia, north-central Chile, and northwestern Argentina. The greater flamingo (the most widespread of all flamingo species) is located in northwest India, the Middle East, the western Mediterranean, and Africa. The lesser flamingo lives in different parts of Africa and India. The James’s flamingo lives in areas similar to those of the Andean species – Peru, Chile, Bolivia, and Argentina. American flamingos reside in the Caribbean, the Galapagos Islands, and the northern regions of South America. Finally, the Chilean flamingo can be found in Peru, Argentina, Uruguay, Paraguay, Bolivia, and Brazil.

The colorful birds live in large groups called a flamboyance or a stand. Each group can have thousands or even millions of flamingos. The large groups help to keep the birds safe from predators and offer them the ability to locate food more effectively. Every year in Kenya, a large stand of over 1 million lesser flamingos gathers at Lake Bogoria to feed on a special blue-green algae, one of the foods that contributes to the birds’ pink plumage. They spend hours at the lake feeding and drinking until they begin departing in flocks of around 100,000 flamingos at a time.

Gathering in such large groups, it is important to note that flamingos are incredibly social creatures. They use a wide range of vocal calls to communicate. The sounds can be grunts or growls, to horns and honks. Flamingo parents can recognize and locate their young by the sounds they produce.

Though the adults are often pink or crimson, baby flamingos are born with soft, white, downy feathers. Initially, they have straight bills that begin to fold downward as they age. Both parents care for the babies by feeding them a special milk-like fluid produced by their digestive systems. Within about five days, baby flamingos begin to leave the nest and return to feed. Around three weeks old, babies form groups called crèches and begin learning to find food on their own. At about three months old, they have grown their flying feathers and are ready to leave their parents for good.

Depending on their species, the color of adult flamingos ranges from pink to crimson. Their color is dependent on their diets. Their favorite foods are shrimp, snails, and algae. They eat by turning their heads upside down in the water and filtering the food through their tongues and bills using a special hair-like structures called lamellae.

A flamingo’s body is slender, and their necks and legs are long and flexible. Their legs appear to bend backwards; however, what appears to be their knees is actually their ankles. They have webbed feet that they use to gain speed on the water’s surface before taking flight. Each species is slightly different in height and weight. On average, flamingos stand nearly 4 ft. tall and weigh approximately 5.5 pounds.

A strange and scientifically baffling behavior is a flamingo’s habit of standing on one leg. Scientists remain unsure why the animals do this. However, a couple of potential reasons are that it conserves body heat or that it reduces the amount of energy used by standing on both legs. Some studies have shown that the effort required to stand on one leg is minimal, and the birds can easily balance in that position.

Lifespan and Predators

In the wild, it is common for a flamingo to live between 20 and 30 years old. Those in captivity that are properly cared for can live to be around 50. The oldest recorded flamingo was a greater flamingo that lived in the Adelaide Zoo in Australia. It lived to be 83 years old.

Flamingos are vulnerable to many predators. Eggs and babies are especially vulnerable to large birds of prey, as well as snakes, vultures, storks, and gulls. Other small mammals like foxes, mongoose, and wild cats can be potential predators for the animals as well.

Adult flamingos are at the highest risk of being hunted while they are feeding in shallow waters. The weak or injured ones of the flamboyance, or the ones who find themselves isolated from the group, are at the highest risk of becoming dinner for crocodiles and large birds of prey like eagles or falcons; though these are not incredibly common occurrences.

Flamingos are beautifully odd creatures with mannerisms that even scientists can’t always explain. Their quirky appearance and strange behaviors have captured the attention of people for many decades. Thankfully, there are plenty of them in existence so they can continue to be studied and evaluated for years to come.
