Flamingos or flamingoes[a] /fləˈmɪŋɡoʊz/ are a type of wading bird in the family Phoenicopteridae, which is the only extant family in the order Phoenicopteriformes. There are four flamingo species distributed throughout the Americas (including the Caribbean), and two species native to Afro-Eurasia.
Traditionally, the long-legged Ciconiiformes, probably a paraphyletic assemblage, have been considered the flamingos' closest relatives and the family was included in the order. Usually, the ibises and spoonbills of the Threskiornithidae were considered their closest relatives within this order. Earlier genetic studies, such as those of Charles Sibley and colleagues, also supported this relationship.[6] Relationships to the waterfowl were considered as well,[7] especially as flamingos are parasitized by feather lice of the genus Anaticola, which are otherwise exclusively found on ducks and geese.[8] The peculiar presbyornithids were used to argue for a close relationship between flamingos, waterfowl, and waders.[9] A 2002 paper concluded they are waterfowl,[10] but a 2014 comprehensive study of bird orders found that flamingos and grebes are not waterfowl, but rather are part of Columbea, along with doves, sandgrouse, and mesites.[11]
Recent molecular studies have suggested a relation with grebes,[12][13][14] while morphological evidence also strongly supports a relationship between flamingos and grebes. They hold at least 11 morphological traits in common, which are not found in other birds. Many of these characteristics have been previously identified on flamingos, but not on grebes.[15] The fossil palaelodids can be considered evolutionarily, and ecologically, intermediate between flamingos and grebes.[16]
For the grebe-flamingo clade, the taxon Mirandornithes ("miraculous birds" due to their extreme divergence and apomorphies) has been proposed. Alternatively, they could be placed in one order, with Phoenocopteriformes taking priority.[16]
Flamingos usually stand on one leg with the other tucked beneath the body. The reason for this behaviour is not fully understood. One theory is that standing on one leg allows the birds to conserve more body heat, given that they spend a significant amount of time wading in cold water.[31] However, the behaviour also takes place in warm water and is also observed in birds that do not typically stand in water. An alternative theory is that standing on one leg reduces the energy expenditure for producing muscular effort to stand and balance on one leg. A study on cadavers showed that the one-legged pose could be held without any muscle activity, while living flamingos demonstrate substantially less body sway in a one-legged posture.[32] As well as standing in the water, flamingos may stamp their webbed feet in the mud to stir up food from the bottom.[33]
Flamingos are capable flyers, and flamingos in captivity often require wing clipping to prevent escape. A pair of African flamingos which had not yet had their wings clipped escaped from the Wichita, Kansas, zoo in 2005. One was spotted in Texas 14 years later. It had been seen previously by birders in Texas, Wisconsin and Louisiana.[34]
Young flamingos hatch with grayish-red plumage, but adults range from light pink to bright red due to aqueous bacteria and beta-carotene obtained from their food supply. A well-fed, healthy flamingo is more vibrantly colored, thus a more desirable mate; a white or pale flamingo, however, is usually unhealthy or malnourished. Captive flamingos are a notable exception; even if adequately nourished, they may turn a pale pink if they are not fed carotene at levels comparable to the wild.[35]
The greater flamingo is the tallest of the six different species of flamingos, standing at 3.9 to 4.7 feet (1.2 to 1.4 m) with a weight up to 7.7 pounds (3.5 kg), and the shortest flamingo species (the lesser) has a height of 2.6 feet (0.8 m) and weighs 5.5 pounds (2.5 kg). Flamingos can have a wingspan as small as 37 inches (94 cm) to as big as 59 inches (150 cm).[36]
Flamingos filter-feed on brine shrimp and blue-green algae as well as insect larvae, small insects, mollusks and crustaceans, making them omnivores. Their bills are specially adapted to separate mud and silt from the food they eat, and are uniquely used upside-down. The filtering of food items is assisted by hairy structures called lamellae, which line the mandibles, and the large, rough-surfaced tongue. The pink or reddish color of flamingos comes from carotenoids in their diet of animal and plant plankton. American flamingos are a brighter red color because of the beta carotene availability in their food while the lesser flamingos are a paler pink due to ingesting a smaller amount of this pigment. These carotenoids are broken down into pigments by liver enzymes.[38] The source of this varies by species, and affects the color saturation. Flamingos whose sole diet is blue-green algae are darker than those that get it second-hand by eating animals that have digested blue-green algae.[39]
Flamingos are considered very noisy birds with their noises and vocalizations ranging from grunting or growling to nasal honking. Vocalizations play an important role in parent-chick recognition, ritualized displays, and keeping large flocks together. Variations in vocalizations exist in the voices of different species of flamingos.[40][41]
Flamingos are very social birds; they live in colonies whose population can number in the thousands. These large colonies are believed to serve three purposes for the flamingos: avoiding predators, maximizing food intake, and using scarce suitable nesting sites more efficiently.[42] Before breeding, flamingo colonies split into breeding groups of about 15 to 50 birds. Both males and females in these groups perform synchronized ritual displays.[43] The members of a group stand together and display to each other by stretching their necks upwards, then uttering calls while head-flagging, and then flapping their wings.[44] The displays do not seem directed towards an individual, but occur randomly.[44] These displays stimulate "synchronous nesting" (see below) and help pair up those birds that do not already have mates.[43]
Flamingos form strong pair bonds, although in larger colonies, flamingos sometimes change mates, presumably because more mates are available to choose.[45] Flamingo pairs establish and defend nesting territories. They locate a suitable spot on the mudflat to build a nest (the female usually selects the place).[44] Copulation usually occurs during nest building, which is sometimes interrupted by another flamingo pair trying to commandeer the nesting site for their use. Flamingos aggressively defend their nesting sites. Both the male and the female contribute to building the nest, and to protecting the nest and egg.[46] Same-sex pairs have been reported.[47]
The first flamingo hatched in a European zoo was a Chilean flamingo at Zoo Basel in Switzerland in 1958. Since then, over 389 flamingos have grown up in Basel and been distributed to other zoos around the globe.[52]
While many different kinds of birds were valued items in Roman food, flamingos were among the most prized in Ancient Roman cuisine. An early reference to their consumption, and especially of their tongues, is found in Pliny the Elder, who states in the Natural History:
Although a few recipes for flamingos are found in Apicius' extant works, none refer specifically to flamingo tongues. The three flamingo recipes in the De re coquinaria (On the Subject of Cooking) involve the whole creature:
Most notorious of all was the dinner given by his brother to celebrate the emperor's arrival in Rome, at which two thousand of the choicest fishes and seven thousand birds are said to have been served. He himself eclipsed even this at the dedication of a platter, which on account of its enormous size he called the "Shield of Minerva, Defender of the City." In this he mingled the livers of pike, the brains of pheasants and peacocks, the tongues of flamingoes and the milt of lampreys, brought by his captains and triremes from the whole empire, from Parthia to the Spanish strait.
There is also a mention of flamingo brains in a later, highly contentious source, detailing, in the life of Elagabalus, a food item not apparently to his liking as much as camels' heels and parrot tongues, in the belief that the latter was a prophylactic:
In imitation of Apicius he frequently ate camels-heels and also cocks-combs taken from the living birds, and the tongues of peacocks and nightingales, because he was told that one who ate them was immune from the plague. He served to the palace-attendants, moreover, huge platters heaped up with the viscera of mullets, and flamingo-brains, partridge-eggs, thrush-brains, and the heads of parrots, pheasants, and peacocks.[62]
Flamingo young are born white, with soft, downy feathers and a straight bill. The bill gradually curves downward as the flamingo matures. Both parents take care of the newborn flamingo, feeding it a fluid produced in their digestive systems. The young leave the nest after about five days to join other young flamingos in small groups, returning to the parents for food. The parents identify their chick by its voice. After about three weeks, the adults herd young flamingos into large groups called crèches where they start to look for food on their own.
You can use plain text and mail-tags in the value for each line. You can also use multiple mail-tags in a line; if you have input fields for first name and last name instead of a single name field, you may want to set up the flamingo_name like this:
In order to fly, flamingos need to run a few paces to gather speed. This speed is not related to the ground but rather to the air, so they usually take off facing into the wind. In flight, flamingos are quite distinctive, with their long necks stretched out in front and the equally long legs trailing behind. Their outstretched wings showcase the pretty black and red (or pink) coloration that, with slight variations, is shared by all flamingo species. When flying, flamingos flap their wings fairly rapidly and almost continuously. And, as with most other flamingo activities, they usually fly together in large flocks. The flamingos follow each other closely, using a variety of formations that help them take advantage of the wind currents.
