What Makes Flamingos Pink – As you know, flamingos are beautiful birds that are often seen in pink. However, their feather color is not hereditary, so there are no genes in their DNA that could pigment them. So why are they pink?
In fact, all flamingos are born gray and turn pink, white, or even orange later in life due to their specific diet. Flamingos typically live near water, so they feed primarily on shrimp, algae, and shellfish, all of which can have a pink/orange pigment called a carotenoid. When consumed, enzymes in the flamingo’s digestive system break down the carotenoids into orange and pink pigment molecules. In the liver, these molecules are absorbed by fats and then accumulated throughout the flamingo’s body, such as in its skin, legs, feathers and even its beak.
What Makes Flamingos Pink
However, flamingos are not always pink. Some may have lighter or darker shades of pink, be slightly orange, or even a little red. Their color can vary depending on their location and the food they eat. For example, Andean flamingos are mostly white because their diet does not contain much carotenoid pigment due to their location in the Andean mountains of South America.
Like Humans, Flamingos Make Friends For Life
Flamingos can also change color before mating season. During this time, they need to appear as bright as possible to attract mates, because the pinker the flamingos, the healthier they are. Therefore, those that are pinker are more likely to mate and produce healthy offspring! However, after this, both females and males may lose their pigments. This is because the majority of food is used during the mating season and is then fed to the chicks. The flamingo is one of the most famous and majestic birds. They are characterized by their beautiful pink color. But what is the origin of this color?
Thanks to its acidic algae, mineral-rich water and diversity of aquatic creatures, the salt pan is an ideal habitat for pink flamingos.
Pink flamingos are in fact not pink by nature: they become so, in particular because of their diet. They are born white-gray and will gradually turn pink. These large birds live in colonies in wet areas, such as lakes or salt pans. These places offer them a very specific diet: algae, larvae and small crustaceans very rich in carotenoids, pigments which, once digested by the flamingos, will be deposited on their skin and their feathers.
The greater flamingo has a gland that allows it to excrete excess salt through its nostril, so it prefers shallow, salty salt flats, like the salt flats that it frequents in greater numbers in winter.
Medartsal] Did You Know That The Pink Colour Of Flamingos Comes From The Salt Flats?
Algae found in salt lagoons are pink in color and contain photosynthetic pigments. These are carotenoids, like those found in carrots or many other vegetables and plants. Once the bird has swallowed this pigment, it will be transmitted and then retransmitted throughout the food chain.
It is therefore as they age that pink flamingos will acquire their pink color. However, it is not uniform between individuals, varying from very pale to very dark. It depends on the type of environment the flamingo is in and how much food it can find there.
The color of pink flamingos is an asset for the species since it allows the bird to be less visible in its environment, the salty lagoons, often tinged with pink. Some experts believe that the color may have become more intense over the centuries due to the principle of survival. Carotenoids have antioxidant properties and strengthen the immune system. This means that the pinker the bird, the healthier it is and the better it resists infections. Pink flamingos would therefore tend to turn towards the brightest individuals of their species when mating.
In Tunisia, the number of flamingos varies between 800 and 1,000 in summer. In September, with the start of the migration, the sanctuary welcomes between 3,500 and 4,000 pink flamingos.
Amazing Facts About Flamingos
To admire this landscape, you can go there all year round, but the spectacle is even more impressive in spring, during the breeding season and then in February-March, during the laying period. Flamingos are found mainly in the salty lagoons that stretch from the north to the south of Tunisia.
In the north, they are found mainly in the lagoons of Tunis and at Cap Bon, more precisely in the Korba lagoon. In the south, pink flamingos live in the salt pans of Sfax and in Djerba on the flamingo island all year round.
Today, the salt pans of the Mediterranean suffer from environmental pressures and economic tensions. In this context, the ENI CBC Med program launched the MedArtSal project which aims to define a sustainable and adaptable management model for artisanal saltworks including, among other things, a strategic marketing plan and a biodiversity strategy to preserve pink flamingos and other species. living in salt flats. Known for their long legs and bright pink feathers, flamingos are wading birds found in the Americas, Asia, Africa and parts of southern Europe, although they are known to thrive as far north as Germany.
The name flamingo comes from the Portuguese/Spanish word “flamengo” which translates to “flame color” in relation to their vibrant feathers. However, they are not actually born pink. Instead, when flamingo chicks hatch, their feathers are a dull gray.
Why Are Flamingos Pink In Colour? Find Out The Facts About Flamingos
The reason flamingos are pink is due to their diet of algae, shrimp, and shellfish. The wetland habitats they inhabit are teeming with blue-green algae which, despite its name, is actually red or orange in color due to a chemical called beta-carotene. This chemical contains a red-orange pigment called a carotenoid, which is also found in carrots, sweet potatoes and spinach.
Once eaten, enzymes in the flamingo’s digestive system break down the beta-carotene, and the red-orange pigments are absorbed by the fat in its liver. These fats are then deposited in the flamingo’s feathers and skin as it grows. Since their diet is almost exclusively composed of rich sources of beta-carotene, flamingos gradually turn pink.
The coloring of flamingos can vary because carotenoid levels in algae and shellfish also vary across the world. Flamingo species found in the Caribbean are often bright red or orange, while those in drier areas tend to be a paler pink color. Without a high enough concentration of beta-carotene-rich food, the pink feathers would molt and new, paler feathers would begin to grow.
Although the sight of a colorful flamingo is familiar, there are many ways it can lose its distinctive hue. The carotenoids themselves can bleach in the sun, which the flamingo species

Fights by preening directly with pigments secreted from their glands, giving their feathers a brilliant pink sheen.
Flamingos are also one of the few birds that feed their young with plant-based milk. Not to be confused with milk produced from mammalian species, cultured milk produced by flamingos is a highly nutritious bright pink secretion produced in an adult’s throat and is so densely packed with carotenoids that At the end of the breeding season, both male and female parents often appear. white, losing the pink coloring of their feathers.
Despite numerous reports of blue flamingo sightings online, there is no evidence to suggest they are anything other than internet hoaxes. However, a number of sightings of a rare black flamingo have been seen in Cyprus. He is believed to suffer from a pigmentary disease called “melanism”, causing an overproduction of melanin making him black.

Flamingos are long-legged wading birds usually covered in bright pink feathers. With a name that derives from the Spanish or Portuguese word for “flame color,” the birds are known for their vibrant appearance. The pinkness of their feathers, although it is their most famous quality, is not a hereditary trait. Flamingos are indeed born dull gray. So, if it’s not part of their DNA, why do these birds turn shades of pink?
For flamingos, the phrase “You are what you eat” holds more truth than for humans. The bright pink color of flamingos comes from beta-carotene, a red-orange pigment found in large quantities in algae, brine fly larvae, and brine shrimp that flamingos eat in their humid environment. In the digestive system, enzymes break down carotenoids into pigments that are absorbed by
