In a thriller for scientists and ornithologists, a migratory bird tagged with a GPS device in Mumbai was traced all the way to Siberia, the Bombay Natural History Society said here on Monday.<\/p>\n
Terming it an “Eureka moment”, the BNHS said that the black-tailed godwit, named Bala, after a renowned expert on bird migration Dr. S. Balachandran had taken wings from Mumbai in March.<\/p>\n
It was tagged with a GPS device in Mumbai that month and finally it was traced to a location in southwestern Siberia in June, covering a distance of around 5,000 km across countries.<\/p>\n
It again took flight and returned to Mumbai in just five days, this time covering 4,200 km, and is now resident at the Bhandup Pumping Station in the eastern suburbs.<\/p>\n
The BNHS said that Bala’s return proved the birds’ typical habit of “site fidelity”, ot a return to the same site that they are accustomed to.<\/p>\n
It is now studying and analysing the entire flight pattern of Bala and will publish it in a report form soon, said Deputy Director, Dr. Rahul Khot.<\/p>\n
BNHS’ Dr Balachandran is a reputed scientist with over four decades of study and research at various destinations like Chilka in Odisha and Bharatpur in Rajasthan.<\/p>\n
Prior to this, the BNHS has deployed six GPS\/GSM tags on three greater flamingos and three lesser flamingos from January to April 2022 to understand the flamingo migration, and all the pink birds have landed in Gujarat.<\/p>\n
These experiments are part of the BNHS’ study on long-term ecological monitoring of migratory birds visiting the Thane Creek since 2017.<\/p>\n
In order to better understand the wintering birds’ habitat use, migration patterns and other aspects, the scientists deploy bird rings and colour flags at sites around Thane Creek.<\/p>\n
So far, the BNHS has ringed or flagged around 21,000 birds and has been able to trace and track them within India or foreign countries.<\/p>\n","protected":false},"excerpt":{"rendered":"
