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.
