Chennai, 19 October (H.S.) : The Puthalam saltpans in Kanniyakumari district have become the focus of the birdwatching community after two rare species of terns—the Arctic tern (Sterna paradisaea) and the white-cheeked tern (Sterna repressa)—were recorded for the first time in Tamil Nadu.

The landmark sightings, documented on September 13 and 14, have been listed on the global birding platform eBird, significantly elevating the ornithological profile of the site. The presence of these visitors underscores the critical role the saltpans play in supporting transcontinental migratory species.

The state’s first-ever Arctic tern sighting was made by independent bird researcher Anand Shibu. This species is famous for undertaking the longest annual migration in the animal kingdom, covering nearly 70,000 km between the Arctic and Antarctic regions.

This record marks only the fifth instance of an Arctic tern sighting across India. The following day, a team including fellow birder Bagavathi Balasubramanian recorded the white-cheeked tern, a species typically inhabiting the tropical coasts of the Red Sea and the Indian Ocean. With 224 bird species now recorded, Puthalam has cemented its status as an essential wintering, feeding, and roosting ground for waders from distant continents.

The significance of the Puthalam saltpans is further highlighted by the sighting of other rare and near-threatened species in August, including the red knot and the red-necked stint. However, conservationists have raised serious concerns regarding the future of the habitat. Experts warn that the crucial site faces environmental threats from unregulated garbage dumping and continuous encroachment pressures.

Authorities and conservationists emphasize that protecting the integrity of the saltpans and the adjoining mudflats is paramount to sustaining these migratory species that rely on the area for rest and nourishment during their long journeys.
