South Bihar Wetlands See Bird Population Boom

Wetlands in south Bihar have reported a substantial increase in waterbird populations this year, marking a positive ecological development. The Asian Waterbird Survey, conducted between January 18 and February 8 by scientists from the Central University of South Bihar and forest department officials, covered 12 wetlands across six districts.

Findings revealed significant population growth at several wetlands compared to the previous year. Indrapuri Barrage Wetland, a major water body in Bihar, recorded a more than threefold increase, hosting 7,829 birds from 66 species, up from 2,268 birds of 58 species last year. This surge included new species like the Common shelduck and a variety of migratory ducks.

Other key areas like Hardiya Dam and Jog Jalashay in Nawada district also showed healthy bird counts. Dharaut pond in Jehanabad was a notable surprise, supporting over 2,300 waterbirds. The Gangetic river basin from Mahuli ghat to Maner ghat in Bhojpur also saw a diverse range of species and even Gangetic dolphins. Researchers also evaluated habitat suitability and human impact to aid conservation planning.
