The annual bird census in five ranges under the Chilika wildlife division in the Chilika Lake will be conducted from 6 am to 11 am tomorrow, they added.
Counting of birds, both domestic and migratory, will be carried out in wildlife ranges of Ramba, Satapada, Chilika, Tangi and Nuapada.
The Chilika Lake, spread over the Puri, Khurda and Ganjam districts of Odisha, is the largest brackish water lagoon of Asia.
Notably, the practice of counting birds has been exercised every year in Chilika. As many as 48,728 birds of 106 species were counted at the lake during the annual summer survey held in May last year.
Migratory birds mostly come to Chilika from beyond the Himalayas every winter — from northern Eurasia, the Caspian region, Siberia, Kazakhstan, Lake Baikal and remote areas of Russia and neighbouring countries. They start their homeward journey before the onset of summer.
