Greater Flamingo
The Greater Flamingo (*Phoenicopterus roseus*) is the most widespread flamingo species, renowned for its vibrant pink plumage, long legs and neck, and distinctive downward-bending bill. These birds are highly social, often forming large flocks in saline or alkaline lakes and lagoons. Ecologically, they play a crucial role in their habitats as filter feeders, influencing water quality and nutrient cycling. Culturally, flamingos have been depicted in art and mythology across various civilizations, symbolizing beauty, balance, and grace.

Conservation Status
Distribution
Found in parts of Africa, southern Europe, the Middle East, and the Indian subcontinent. They are partially migratory, with some populations moving seasonally in response to water levels and food availability. Altitudinal range varies from sea level to high-altitude saline lakes in some regions.
Lifespan
In the wild, Greater Flamingos can live for 30-40 years, and even longer in captivity.
Greater Flamingo's Habitat
Habitat Types
Saline lakes, Alkaline lakes, Coastal lagoons, Estuaries, Salt pans
Climate Zones
Tropical, Subtropical, Temperate
Adaptations
Greater Flamingos possess specialized salt glands that excrete excess salt, allowing them to thrive in highly saline environments. Their long legs enable wading in deeper water, and their specialized bill structure is adapted for filter-feeding.
Variations
While *Phoenicopterus roseus* is generally considered a single species, some regional variations in size and plumage color intensity have been observed, although not formally recognized as distinct subspecies.
Appearance
Breeding Plumage
Breeding plumage is generally brighter pink, while non-breeding plumage can be paler. The intensity of the pink coloration is influenced by their diet, specifically the carotenoid pigments in the crustaceans and algae they consume.
Seasonal Feather Changes
Plumage color may fade somewhat outside of the breeding season.
Sex Based Plumage Differences
There is minimal sexual dimorphism in plumage, although males may have slightly brighter coloration during the breeding season.
Notable Features
Long, pink legs with backward-bending knees (actually ankles)., Long, curved neck., Distinctive downward-bending bill, black-tipped and pink., Pink plumage, varying in intensity.
Diet and Feeding
Primary Foods
Small crustaceans (e.g., brine shrimp), Algae, Mollusks, Insect larvae, Seeds of aquatic plants
Foraging Behavior
Greater Flamingos feed by standing in shallow water, submerging their heads, and sweeping their bills from side to side. They use their specialized, filter-like lamellae inside the bill to strain out food particles from the water and mud.
Specializations
Their bill has a unique structure with lamellae (comb-like structures) that act as filters, trapping small food items while expelling water. The tongue also plays a role in pumping water through the bill.
Seasonal Diet Variations
Diet can vary depending on the availability of food items in different habitats and seasons. For example, during periods of high rainfall, they may consume more insect larvae.
Behavior
Social Structure
Highly social birds, forming large flocks that can number in the thousands, especially during the breeding season. They also form smaller groups outside of breeding.
Communication
Loud honking calls, Grunting sounds, Visual displays (head movements, wing displays)
Migration
Some populations are migratory, undertaking long-distance movements between breeding and feeding grounds. Migration is often triggered by changes in water levels or food availability.
Territorial or Group Behaviors
While generally not highly territorial, flamingos may defend a small area around their nest during the breeding season. The large flocks provide protection from predators.
Conservation
Threats
Habitat loss and degradation (due to wetland drainage, pollution, and human disturbance), Climate change (altering water levels and salinity of feeding grounds), Lead poisoning (from ingestion of lead shot), Human disturbance at breeding colonies, Egg collection (in some regions)
Protection Programs
International agreements (e.g., Ramsar Convention on Wetlands), Protected areas (national parks, reserves), Habitat restoration projects, Monitoring programs
Local National Laws
Protected under various national and international laws, including the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).
Population Trend
Stable
Population Estimates
The global population is estimated to be between 550,000 and 680,000 individuals.
Interesting Facts
Flamingos get their pink color from their diet.
The carotenoid pigments in the crustaceans and algae they consume are responsible for their pink or reddish plumage.
Flamingo chicks are born with gray or white down feathers.
They develop their pink coloration over time as they consume carotenoid-rich foods.
Flamingos often stand on one leg.
This behavior is thought to help conserve body heat and reduce muscle fatigue.
The 'knee' of a flamingo is actually its ankle.
The true knee is hidden higher up, close to the body and hidden by feathers.
Flamingos can drink near-boiling water.
Some populations feed near hot springs and geysers and have adapted to tolerate extremely hot water temperatures.
Faqs about Greater Flamingo
Why are flamingos pink?
Their pink coloration comes from the pigments in the crustaceans and algae they eat.

Where do flamingos live?
They inhabit saline and alkaline lakes, lagoons, and coastal areas in parts of Africa, southern Europe, the Middle East, and the Indian subcontinent.
Do flamingos migrate?
Some populations are migratory, moving in response to changes in water levels and food availability.
What do flamingos eat?
They filter-feed on small crustaceans, algae, mollusks, insect larvae, and seeds.
