Berhampur, Feb 23 (LocalWire) With the rise in temperature in Chilika lake, thousands of winged migratory guests, who have made it their home during winter, have begun their onward journey towards their summer nesting place.
The sprawling blue lagoon, spread across Odisha’s Puri, Khurda and Ganjam districts, is the country’s biggest waterfowl habitat, where the migratory birds come in thousands to nest during winter.
The birds come here from Eurasia and the Caspian region nations like Russia, Siberia and Kazakhistan to escape the harsh winter.
In this season, though, they have arrived late and leaving early, said DFO Bikash Ranjan Das.
The birds generally come to Chilika during the second week of October and leave during the first week of March, with the onset of summer. This time, they are leaving in the third week of February, the DFO said.
An expert attributed this change in their nesting period to global warming.
“Sudden rise in temperature and abnormal weather condition are some of the reasons for their early return,” said Sudhakar Mohapatra, a retired senior forest officer.
Chilika hosted over a million birds of 181 different species during this winter. The birds include 105 species of waterfowls and 76 species of water dependent birds.
Majority of them had taken shelter in the Nalabana area of the sanctuary. In the past few years, it was observed that several species of migratory birds, mainly the duck species, had refused to leave the lagoon.
Like the previous year, this year too the birds were seen flocking in new areas of the lake like Parikuada, and Krushna Prasad after the eviction of the prawn gheries (enclosures).
