Context

• Chilika lake in Odisha, Asia’s biggest brackish water lagoon, saw an increase in the number of migratory birds this winter compared to the previous year.

Background

• The Chilika Wildlife Division (CWD), Chilika Development Authority and Bombay Natural History Society (BNHS) jointly carry out the annual bird census at the Ramsar site.

  

• Habitat improvement, availability of food and eviction of the prawn gherries (enclosures) in the lake are some of the reasons for the increase

Key Birds sighted at Chilika lake

• River Lapwing (Vanellus duvaucelii), a tiny bird of the lapwing species, on the Mangalajodi side of the lake after a decade.
• Gadwall and Northern Pintail contributed the most to the surge, followed by Eurasian Wingeon.
• The number of Northern Shoveler, Tufted Ducks and Red Crested Pochard increased compared to last year.
• The birds mainly come from Northern Eurasia, the Caspian region, Siberia, Kazakh, Lake Baikal and the remote parts of Russia and its neighbouring countries.
