Rangpur: The arrival of migratory birds from the northern hemisphere before the onset of winter is transforming rivers, canals, beels, and water bodies in the northern region into scenic spots, delighting people from all walks of life. Amid the adverse effects of climate change, these birds are arriving earlier this year compared to previous decades when they typically arrived in December.
According to Bangladesh Sangbad Sangstha, environmental experts, observers, and common people have noted that the number of migratory birds arriving from the cold northern hemisphere could be relatively higher this year compared to previous years. Begum Rokeya University Professor and Director of Riverine People, environmentalist Dr. Tuhin Wadud, highlighted that the abundance of food sources such as small fish, insects, snails, and aquatic plants in the northern water bodies supports the sustenance of these birds upon their arrival.
Dr. Wadud recalled that four decades ago, many migratory birds could be seen in the rivers and water bodies in the Brahmaputra basin of the northern region. However, recent years have seen a decline in their numbers due to the reduction in water bodies and the loss of plants, animals, and freshwater fish due to climate change. He expressed concern that if climate conditions continue to deteriorate, the number of migratory birds may decline again due to a lack of food in shrinking water bodies.
Dr. Syed Samsuzzaman, Chairman of the Northbengal Institute of Development Studies, noted that climate change has increased average temperatures in regions like the Himalayas, Siberia, Xinjiang, and Mongolia, making them more suitable for bird habitats even in winter. This change had previously led to a decrease in migratory bird arrivals in northern water bodies, but the current season shows a slight increase.
Locals have reported sightings of migratory birds in the Brahmaputra, Teesta, and Jamuna rivers, as well as in Ramsagar Dighee in Dinajpur, Chatra Beel in Rangpur, and many other water bodies in the region. Visitors are flocking to these areas to witness the birds' graceful flying and landing movements.
Engineer Md Habibur Rahman Khan, Superintending Engineer of the Barind Multipurpose Development Authority for Rangpur Circle, confirmed that migratory birds have already started arriving in the northern region's rivers and water bodies. Species such as Chhota Sarali, Bara Sarali, Bali Lenja, and others are mostly arriving in the Brahmaputra basin, adding to the vibrant natural display.
The Bharardaho Beel in Badarganj upazila of Rangpur, re-excavated by BMDA and home to a wide array of flora and fauna, has become a sanctuary for migratory birds. The area is now filled with the chirping and fluttering of guest birds, attracting many visitors.
Housewife Gulnahar Begum, who visited Bharardaho Beel with her family, described the experience as heart-warming and divine, appreciating the peaceful scene created by the orderly flight and chirping of the birds. Her family echoed her sentiments, expressing fascination with the beauty of the beel, enhanced by the presence of green nature and blooming flowers.
