He said the annual bird count, conducted over 1,100 square kilometre of the lake area found 11,05,040 birds of 184 different species. These included 10,71,477 waterfowls of 109 species and 33,563 of 75 species of wetland dependants, Hota said.

Increase in number of migratory birds in the lake is attributed due to the safety measures taken by the wildlife authorities and improvement of the habitat in the lake, said the DFO.

Ornithologists said the huge arrival of migratory birds indicates that cyclone Fani, which battered the lake at Puri in May this year had no impact on the winged visitors.
