BHOLA, Dec 30: The number of migratory birds arriving in the coastal char areas of Bhola, Laxmipur, Noakhali and Patuakhali districts has increased this year.
Around 41,675 migratory birds of 62 species arrived in the coastal area this year, whereas about 35,000 arrived last year. This information was disclosed after a survey of migratory birds in the area that concluded on Monday.
The survey was conducted by a four-member team of Nature Conservation Management (NACOM) and Bangladesh Bird Club survey group led by bird ringer and wildlife researcher Samiul Mohsanin.
After completing the seven-day long bird survey on Monday, Samiul Mohsanin said the number of migratory birds coming to this area is rising consistently for the last two years. This time they have visited 30 char lands including Monpura, Majher Char, Banger Char, Domar Char, Char Shahjalal, Sonar Char, Dhal Char, Char Kukri Mukri, Ander Char in Bhola and other chars in Laxmipur, Noakhali and Patuakhali districts.
This survey was conducted under the Strengthening Regional Co-operation for Wildlife Protection (SRCWP) project of Forest Department.
But the researcher expressed concern over decrease of bird sanctuaries in the coastal char lands at the Meghna-Brahmaputra-Ganges delta islands, where the migratory birds take shelter during the four months of winter.
He also said that the migratory bird population is facing threats from poachers. The number of these birds might be reduced in future due to increasing hunting pressure, human disturbances, decrease of char lands and continuous river pollution, he added.
In the previous years, about 23,000 migratory birds of 64 species arrived in 2012, while 35,000 birds of 65 different varieties came in 2013, revealed the bird survey group.
This census, however, will be continued to monitor the seasonal variations and to understand the existing threats. Conservation measures will be taken based on these findings.
