Two tagged migratory birds — a redshank and a whiskered tern — have been noticed within the salt pans of Swamithoppu within the Manakudy fowl reserve in Kanniyakumari district.
Davidson Sargunam, a fowl watcher and conservation educationist, has noticed the birds. He says the reserve has an ample provide of freshwater fish fauna, crustaceans, barnacles and freshwater weeds, and has offered the birds safety and a protect from sound air pollution.
Yearly, birds from European international locations go to the reserve for wintering from September to November. They depart by March or mid-April, relying on the provision of water within the wetlands, Mr. Davidson says.
S. Balachandran, Deputy Director, Bombay Pure Historical past Society (BNHS), says that is the primary time a whiskered tern, marked exterior the nation, is reported from India. “Because the numbers within the ring aren’t seen, we’re unable to conclude from which nation the fowl has migrated,” he says.
The whiskered tern is presumably from European international locations. “There are terns that breed in India, however these birds won’t come right here,” he causes.
In keeping with Mr. Balachandran, there are 5 sub-species of redshank, they usually migrate from the Himalayas, China, Mongolia and the Russian Far East.
“The redshank noticed in Kanniyakumari district is presumably from the subarctic area and it could possibly be one of many birds tagged by the BNHS. We comply with the follow of tagging birds on the tibia, the higher leg of the fowl. It was both from Level Calimere or Mumbai, the 2 locations the place these birds have been marked in appreciable numbers,” he says.
Tagging helps ornithologists and scientists examine the gap that birds journey, the areas they go to, the variety of days they take to achieve the wintering spots, meals availability, water high quality, climatic components, habitat areas, challenges they face and human intervention within the wintering spots.
