Their life expectancy of 40 years is one of the longest in birds. Birds, however, lack a urinary bladder and must compensate using these three organs. In mammals, the kidneys and urinary bladder are the primary organs used in osmoregulation. ruber, the kidney, the lower gastrointestinal tract, and the salt glands work together to maintain the homeostasis between ions and fluids. It has evolved long legs and large webbed feet to wade and stir up the bottom of the water bed to bring up their food source to then be retrieved. The flamingos beak is equipped with tiny layers. The American flamingo has adapted to its shallow-water environment in several ways. Flamingos feed on insect larvae, algae, and a great variety of invertebrates that are obtained by filtration. The bill is pink and white with an extensive black tip. The wing coverts are red, and the primary and secondary flight feathers are black. Most of its plumage is pink, giving rise to its earlier name of rosy flamingo and differentiating adults from the much paler greater flamingo. Lesser, James' and Andean flamingos are more specialised in straining algae whereas Greater, Caribbean and Chilean flamingos are more adept at straining larger organisms such as crustaceans, larvae, molluscs and small fish.The American flamingo is a large wading bird with reddish-pink plumage. It’s a complex and highly adapted filtering system that can also be observed in some waterfowl such as Mallards. This upside-down stance allows flamingos to accurately scoop water in their high capacity upper bills and pump the water through hair-like lamellae which effectively strain even very small creatures like algae and diatoms. Their lower bill is actually much stronger than their upper bill and can move independently, enabling the flamingo to rapidly pump water through its internal filtering system. With a deep, fiery pink, the American Flamingo really stands out as one of the most beautiful among its peers. The color pink comes from beta-carotene in the crustaceans and plankton that flamingos eat. Their bill is adapted for this too and has quite a pronounced downwards curve. The American flamingo (Phoenicopterus ruber) is the only flamingo species native to North America.
The Andean Flamingo and the Jamess Flamingo are. Prior to feeding, flamingos often stomp their feet on the lake or lagoon bed to stir up mud and sediment, releasing algae and other foods in the process.įlamingos are known as filter feeders and feed with their heads upside down, facing backwards towards their bodies. The American Flamingo is also large but generally does not have such a pale plumage as the Greater Flamingo. Read on to discover more about the feeding habits of this quirky bird! Interestingly, their pink hues have come to affect them in other ways, too, as healthy mates are often selected based on how dark pink their plumage is, thus indicating that they have a particularly rich diet.
Whilst all species of flamingos have similar diets, the quantities and type of algae they consume have a bearing on how pink they are. Once metabolised, these carotenoids dye flamingos pink.
#American flamingo color full
Algae is full of carotenoids - naturally occurring nutrients and pigments that are also found in colourful vegetables like carrots, peppers and tomatoes. Their diet consists mainly of algae and shrimp, and other shellfish that also consume algae. These tall wading birds have an interesting diet to match their other funky characteristics, so what do flamingos eat?įlamingos are not born pink but instead turn pink throughout their lives due to their algae-rich diet. On the other hand, the lack of abundant beta-carotene in the food of African flamingos results in them being of a paler pink color (Amat et al. Flamingos are actually the only bird left in their order Phoenicopteriformes - the rest are extinct. For example, the high beta-carotene content in the diet of American flamingos is reflected in the brightest red color. Why are some flamingos pinker than others?įlamingos are for sure one of the most bizarre-looking birds around, famed for their pink dyed plumage, long legs and unusual collective mating displays.
