BSS, Rangpur :
The migratory guest birds have started arriving to the water bodies, including beels, haors and major rivers, everywhere in northern districts from the Himalayan and Siberian regions with advent of the winter.
The number of migratory birds has been continuing to reduce following climate change impacts due to rise in the global temperature though the guest birds had been arriving to the area in huge number even 10 to 15 years back.
Agriculture and Environment Coordinator of RDRS Bangladesh Mamunur
Rashid said the rising temperature in the Himalayan, Siberian, Nepal, Xinxian and Mongolian regions in recent years makes those places almost habitable for birds even during the winters.
As a result of the arising situation, the number of arriving migratory bird decreases with possibilities of further declination in future unless proper steps were taken by the global communities to decrease the extent of degrading climatic condition.
Elderly people Aminur Rahman and Khoka Mian said a fewer number of Bali Duck, Samukal, Bright, Rose King, Bali Lenja, Chity, Sorail, Boikal, Nilshir, Piyang, Pankouri, Rangamuri, Pintail, Pantamukhi, Chokha-chokhi and Khonjona are now being found flocking to the northern districts.
Nazmul Haque and Nazim Uddin said they find only fewer numbers of
migratory birds in Char Narayanpur, Jatrapur, Noonkhawa, Astomirchar,
Noyarhat, Mohanganj, Tazerhat Madarganj, Begumganj, Hatia and Kodalkati now in the Brahmaputra, Teesta, Dudhkumar and Dharla river basins. Horticulture Specialist of the Department of Agriculture Extension
Khandker Md Mesbahul Islam told BSS that the migratory birds are living now on small fishes, insects, small snails and watery plants after arriving from colder regions in the north.
Advisor- Agriculture of BRAC International (Asia and Africa) Dr MA Mazid said the migratory birds are not being seen in uncountable numbers due to reduction of water bodies and depletion of many species of sweet water fishes from the marshes.
He blamed climate change impacts for creating threats to the bio-
diversity, agriculture, ecology and environment reducing number of many species of fishes, insects, birds and some animals causing grave concern to natural balance on the earth.
Dr Mazid said the number of arriving migratory birds reduces and their duration of stay shortens in the water bodies as the same are being dried up much earlier before the end of the winter season following climate change being caused by global warming.
Chairman of Astomirchar union Sohrab Hossain, Professor Nazmul Huda and Editor of the Weekly Juger Khabar Nurul Amin Sarker of Chilmari upazila said the number of migratory birds marked significant reduction in recent years in the Brahmaputra basin.
