bar-headed-geese-find-new-home-in-kondajji-lake

In news: The Mongolian geese have been sighted in plenty in Kondajji lake which is 14 km away from their earlier abode at Kundavada lake in Davangere(Karnataka).

The Bar-headed Geese:

  • Categorised as Least Concern (LC) by the IUCN.
  • Winter migratory birds that travel from Central Asia and Mongolia to as far as Peninsular India.
  • They are known for flying at extreme altitude in their sojourn while crossing the mighty Himalayas, where the oxygen level is less than 10% of what is found at sea level.

Why did they abandon the Kundavada lake ?

  • Indiscriminate use of fertilisers and pesticides in the nearby fields has made feeding on agricultural fields dangerous. This has also polluted the lake water. 
  • Conversion of agricultural lands into Residential complexes has caused a shortage of food for the birds. 
  • Increase in human movements and unabated construction too have annoyed these birds. 

Importance

  • The sighting of over 430 geese in the nearby Kondajji lake is being seen as a ray of hope for ornithologists who were concerned after not even a single goose was sighted in 2019 in the Kundavada lake.
  • This shift in their destination also puts the onus on the Government to ensure least human interference in the bird’s new-found home.
