BHOLA, Feb 28: The number of migratory birds arriving in the coastal char areas of Bhola, Laxmipur, Noakhali and Patuakhali districts has greatly decreased compared to the number of last year.
Around 31 thousand migratory birds of 74 species arrived this year in the coastal areas whereas 42 thousand birds arrived last year.
This information was disclosed after a survey of migratory birds in the coastal areas that concluded on Saturday.
The migratory bird survey was conducted by a seven-member team of Nature Conservation Management (NACOM) and Bangladesh Bird Club. The survey led by bird and wildlife researcher Samiul Mohsanin was made under the Strengthening Regional Co-operation for Wildlife Protection (SRCWP) project of the Forest Department.
After concluding the bird survey on the seventh day on Saturday, 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 in Bhola, Laxmipur, Noakhali and Patuakhali district, and among these, they have visited Monpura, Majher Char, Banger Char, Domar Char, Char Shahjalal, Sonar Char, Dhal Char, Char Kukri Mukri, Ander Char and several thinly populated chars in Bhola.
But he expressed concern on the decrease in bird sanctuaries in the coastal char lands of the river Meghna-Brahmaputra-Ganges delta islands, where the migratory birds take shelter during four months of winter. He also said that the migratory bird population faces threats from poachers.
The number of migratory birds may be reduced in future due to increased poaching pressure, human disturbances, decrease of char lands and continuous river pollution, he added.
In previous years, about 23 thousand migratory birds of 64 species arrived in 2012 while 35 thousand birds of 65 different species came in 2013 and 42 thousand birds of 62 different species came in 2015, revealed the bird survey group.
This water-bird census will continue to monitor the seasonal variations and to understand the existing threats, the survey group informed, saying conservation measures will be taken based on these findings.
