Sambalpur, Jan 8: The annual bird census at Hirakud Reservoir is set to begin on 18th January, with preparations completed by the Hirakud Wildlife Division. Seventy bird experts will be stationed across 32 boats to carry out the survey, which will run from 5:00 AM to 6:00 PM, covering an area of approximately 550 square kilometers of the reservoir, said Anshu pragyan Das, officer of the Hirakud Wildlife Division.
Last year, Hirakud Reservoir welcomed 3,77,732 migratory birds, including species from Europe and America that arrived in the region for the first time. Notable species observed included Eurasian Wigeon, Gadwall, Mallard, Small Grebes, Terns, Bar-headed Goose, Tufted Duck, Pochard, Whistling Duck, Sandpipers, and Northern Pintail.
The census will cover the area between Hirakud and the Power Channel near the Chhattisgarh border, which spans around 700 square kilometers. In recent years, the number of migratory birds visiting the area has steadily increased, and this year, a further rise is expected.
The region typically experiences daytime temperatures of 20–26°C, dropping to around 10°C at night, and the migratory birds usually arrive between mid-November and early March. The availability of abundant food, favorable temperatures, and suitable habitat conditions contribute to the growth in bird populations.
Modern equipment, including GPS devices and cameras, will be provided on each boat to aid in accurate data collection.
Over the past five years, Hirakud Reservoir has seen a consistent rise in both the number of species and birds:
The steady increase highlights Hirakud Reservoir’s growing importance as a key habitat for migratory birds.
