The pink flamingo embodies natural elegance while playing a crucial role in the balance of Mediterranean humid ecosystems. Behind their apparent fragility hide species adapted to habitats threatened by environmental changes.

A Unique Plumage
The greater flamingo (Phoenicopterus roseus) owes its color to its particular diet composed of crustaceans and algae rich in carotenoids, pigments which, once absorbed, tint the feathers pink. This bait, more lively in healthy individuals, is also a criterion of seduction during courtship displays. Their curved beak is a tool of fascinating engineering. When feeding, flamingos dip their heads underwater and use their tongues to pump water and filter nutrients. The tongue pushes water outwards, while thin strips inside the beak capture plankton, algae, and small shrimp. This ingenious mechanism, unique among birds, testifies to the precise adaptation of flamingos to their diet, essential to maintain their pink color.
Did you know?
Flamingos can reach a wingspan of almost 1.5 meters and live up to 30 years in the wild. In captivity, their longevity can exceed 50 years thanks to the absence of predators and a stable diet.
Living Places and Distribution of Pink Flamingos
The Camargue, in the Rhône delta, is home to the only breeding colony of pink flamingos in France. Between the salt waters of the lagoons and the marshes, this habitat is ideal for these gregarious birds which settle there by the thousands for the mating season. In winter, some individuals migrate to warmer regions of North Africa, while others remain in Mediterranean areas. However, pink flamingos are not limited to the Camargue, they are also present in several regions of Africa and South East Asia, which testifies to their great adaptability. Depending on food resources and local climatic conditions, flamingos can travel long distances to find new habitats. Unfortunately, urbanization, intensive agriculture and pollution threaten these fragile ecosystems, disrupting their food resources and limiting their nesting sites.
Did you know?
Nests often erected and made of mud, algae and plant debris which protect the eggs from humidity. This structure, unique among aquatic birds, allows them to keep their eggs safe from frequent flooding in marshes.
Courtship and Family Life
Flamingo courtship displays are a singular spectacle, with hundreds of individuals engaging in synchronized dances, flapping their wings and emitting chorus calls to attract a mate. Once formed, the pairs build a nest high up to lay an egg. The chick is fed a substance called “crop milk”, produced by the parents, rich in proteins and nutrients and essential for its growth. During the first weeks, the young are grouped into “crèches”, a collective strategy which helps protect them from predators. This behavior demonstrates the strength of social bonds within colonies, a rarity in the bird world and an example of social organization.

In pink flamingos, parents produce “crop milk” to feed their young. This fluid rich in proteins, fats and red blood cells is secreted by the cells of their upper digestive system.
Preservation and Conservation Issues
Phoenicopterus roseus, is today threatened by the degradation of its habitat. Climate change represents a major challenge to its survival as increasing temperatures, more frequent droughts and rising sea levels reduce the availability of their food resources and disrupt its breeding range. These changes, coupled with human pressures, create imbalances in wetlands, which are essential for the reproduction and feeding of flamingos. In response, the Camargue National Nature Reserve, in partnership with organizations such as the Tour du Valat, monitors water levels and regulates human activities to protect these territories. Additionally, awareness campaigns aim to promote respectful tourism, informing visitors of the importance of maintaining distance and preserving natural sites.
Did you know?
Flamingos play a vital role in wetlands by regulating plankton populations and influencing nutrient cycles. Their presence thus benefits other aquatic species, such as fish and invertebrates, which benefit from this ecological balance.
Towards a Future to Protect
These waders embody the fragility and beauty of the Mediterranean environment. Preserving these birds also means protecting a unique biodiversity, where each species contributes to maintaining a precious balance. Conservation initiatives, supported by public awareness and scientific efforts, show that it is possible to ensure the survival of these iconic birds in threatened habitats.
