Impact of climate change hits Bhopal wetlands:Migration of migratory birds at Bhoj Wetland stalled at 50–60%

The effects of climate change are now visible not only in Bhopal’s weather but also in its biodiversity. Sudden cold spells followed by rapid temperature increases are directly affecting major water bodies, including Bada Talab, Chhota Talab, Kaliyasot Dam, and Karwa Dam. As a result, this winter’s migratory bird migration is significantly lower than expected. Bird expert Mohammad Khalik said migration this year has stalled at 50–60% of last year’s numbers, whereas historically, the figures should have been much higher. “There is neither an increase nor a major decrease; the situation is relatively stable for now,” he explained. Fluctuating weather disrupts migration patterns According to Khalik, Bhopal has experienced unstable cold patterns this winter, with short bursts of warmth followed by sudden cold. Such fluctuations disturb bird migration. Many migratory birds are now stopping in colder regions and avoiding areas with milder temperatures, which is why central India is seeing fewer migratory arrivals than expected. High water levels affect duck species This year, water levels in Bhopal’s main water bodies remain higher than normal, due to good rainfall, incomplete drainage, and inflow from external sources. This has particularly impacted duck species, which rely on diving to forage. Excess water depth pushes their food out of reach, resulting in insufficient nourishment and creating risks in some areas. Winter bird count 2025–26 On Saturday, the Bhoj Wetland Winter Bird Count 2025–26 was conducted. The event was organized jointly by Bhopal Birds, the Madhya Pradesh State Wetland Authority (EPCO), Bhopal Forest Division, and VNS Nature Savers. Starting at 6 AM, 80 participants surveyed three selected zones of Bhoj Tal: Bishankhedi, Bamhori, and Beel Kheda. Species identified, but numbers low During the count, approximately 110 bird species were recorded, including: The Red-crested Pochard has started arriving in proper numbers. Zone-wise counts were: Bishankhedi – 64 species, Bamhori – 55, Beel Kheda – 45. Hope for increase by February Experts noted that the current numbers are not final. Several duck species typically arrive until the last week of February. If water levels decrease in the coming weeks, the number of migratory birds may increase. At the closing ceremony, EPCO scientist Lokendra Thakkar was the chief guest, and VNS Nature Savers head D.K. Swami was the special guest. Conservation and Monitoring more crucial than ever The event highlighted that wetland conservation and scientific monitoring have become increasingly vital in the era of climate change, ensuring that Bhopal’s rich biodiversity and migratory bird populations are protected.
