Why in News
- Large flocks of migratory flamingos have turned the coastal salt pans of Thoothukudi, Tamil Nadu, into a vibrant feeding and resting habitat.
About Flamingos
- Flamingos are highly gregarious, tall, pink wading birds belonging to the family Phoenicopteridae, which stands as the sole family under the specialized avian order Phoenicopteriformes.
- Renowned for their highly social behavior, these birds gather in massive colonial flocks numbering from hundreds to over a million individuals for flight formations, wading, and breeding.
Natural Habitat
- They primarily colonize highly alkaline or saline shallow lagoons, coastal salt pans, mangrove creeks, tidal mudflats, and inland soda lakes across tropical and subtropical regions.
- The two species commonly found in India include the Greater Flamingo and the Lesser Flamingo.
- These birds migrate systematically from their major national breeding grounds in the Rann of Kachchh, Gujarat, to wintering coastal havens across southern Tamil Nadu, including Thoothukudi, Tirunelveli, and Kanyakumari.
- To safeguard these migration routes, the Tamil Nadu government has formally designated Dhanushkodi as a dedicated flamingo sanctuary to buffer the birds against urban noise and cracker disruptions.
Conservation Status
- The Lesser Flamingo is globally classified as Near Threatened on the IUCN Red List.
- The Greater Flamingo is classified under Least Concern on the IUCN Red List.
Key Characteristics
- Flamingo chicks are born grey-white and gradually develop pink feathers as they mature.
- Their color comes from carotenoid-rich food such as algae, diatoms, crustaceans, and small mollusks.
- Flamingos feed by placing their curved bill upside down in shallow water and stirring mud with their feet.
- Tiny comb-like structures inside the bill filter out food while expelling water.
- During flight, flamingos extend their necks and legs straight, creating a distinctive silhouette with black wing markings.
- They often stand on one leg to conserve heat and reduce muscular effort.
- Flamingos build cone-shaped mud nests in shallow wetlands to protect eggs from flooding.
- Both parents incubate the eggs and later feed chicks with regurgitated nutrient-rich food.
