Phoenicopteridae
Phoenicopteriformes
Birds
30–32 days, in charge of both parents.
Generally one egg per laying.
Present in global zoos; successful programs (such as Basel) include mirror techniques to stimulate breeding
Filter-feeding omnivores. They feed by filtering in shallow waters: they consume algae, diatoms, crustaceans, and small invertebrates, whose carotenoid concentration determines the intensity of their pink color.
In the wild: 30–40 years. In captivity: Up to 60 years.
The greater flamingo is the largest flamingo and one of the most widely distributed on the planet. Its appearance is unmistakable: pinkish-white plumage with more intense shades on the wings, long legs, and a highly curved neck. The characteristic color comes from the carotenoids present in its diet, especially in crustaceans such as Artemia salina. Its downward-curved bill functions as a specialized filter: when placed upside down in the water and moved sideways, it filters small organisms from the mud and water. It has a rough tongue and internal lamellae that facilitate this filter-feeding. The legs are long, pink, and partially palmate, adapted for walking and hovering on soft bottoms. Its wings have a wingspan of up to 2,4 meters, with black feathers visible in flight. Juveniles are born with gray down, which gradually lightens during the first year. This species shows little sexual dimorphism, although males are usually slightly larger than females.
The greater flamingo is highly social and gregarious, living and breeding in colonies that can number more than 10.000 individuals. Their reproductive behavior includes complex synchronized dances performed in groups to attract mates. They are monogamous throughout each season, and both parents collaborate in incubating the single egg they usually lay and feeding the chick with "crop milk." They feed during the day in shallow waters, adopting a characteristic posture: tilting their head downward and moving it from side to side. Their colonial lifestyle favors early detection of predators. They rest and sleep standing up, often on one leg, which helps conserve body heat. Although they are not obligate migrants, some populations make seasonal movements in response to changes in water level or food availability.
The greater flamingo is classified as "Least Concern (LC)" by the IUCN, with estimated populations between 550.000 and 680.000 individuals. Although its global numbers are stable, it relies heavily on protected wetlands, salt marshes, coastal lagoons, and estuaries for breeding and feeding. The loss and alteration of these habitats due to urbanization, intensive tourism, pollution, and climate change represents a latent threat. Furthermore, in some regions, it suffers direct human disturbance during breeding, which can lead to the abandonment of colonies. It is listed in CITES Appendix II, so its trade is regulated. Successful captive breeding programs exist, and some zoos use mirroring techniques to encourage reproductive behavior. Integrated management plans exist in Europe and Africa in areas such as the Camargue (France), Doñana (Spain), and the Nile Delta. Environmental education is essential for its long-term protection.
The flamingo's pink color is not genetic, but rather a result of its carotenoid-rich diet; without these pigments, it would have whitish plumage.
Its distinctive curved beak is perfectly adapted to filtering water and mud, acting as a natural inverted sieve.
Despite its size, the flamingo is an excellent flyer: it can travel hundreds of kilometers between wetlands, flying in V-formations.
They can sleep standing on one leg, reducing heat loss and muscle strain thanks to a natural “locking” system in their joints.
When breeding, both the male and female produce a milk-like nutritive substance, secreted from the crop, with a high fat and protein content.
Their courtship rituals are spectacular: hundreds of flamingos perform synchronized dances with neck movements, wing movements, and turns.
They are very sensitive to disturbance: if a breeding colony is disturbed, it may abandon its nests and eggs en masse.
The chicks gather in “crèches” while their parents search for food.
In flight, their legs extend behind their bodies and their necks are fully extended, giving them an unmistakable silhouette.
They can live up to 60 years in captivity, making them one of the longest-lived birds of their size.
Ringed specimens have been recorded surviving in the wild for more than 40 years.
Its Latin name Phoenicopterus means “purple wings,” referring to the reddish glow of its feathers in the sun.
Although they may appear fragile, they can withstand extreme temperatures in salt lakes, Andean plateaus, and desert areas.
Some populations are partially migratory, and may appear unexpectedly in constructed wetlands or restored salt marshes.
In some ancient cultures, flamingos were a symbol of longevity and beauty; their feathers were used in adornments and rituals.
There are sculptures and paintings of flamingos in ancient Egyptian temples, where they were associated with the god Ra.
They are very vocal birds, emitting a variety of squawks and trumpets, especially during breeding and social interactions.
Its legs, despite appearing thin, are internally reinforced and surprisingly strong.
They have no teeth, but their tongue is rough and muscular, helping to move filtered food toward the throat.
In zoos and reserves, colonies need mirrors and social presence to successfully initiate the reproductive cycle.
