Even just two years ago, Jayapara lake -- the largest lake on the campus of Jahangirnagar University -- would offer itself as a safe haven for local and migratory birds. These birds would be seen resting on the water or fluttering about among bloomed water lilies -- a sight people from all over the city would travel to JU for.

The chirping sound of migratory birds pierces the silence at Char Moazzin in Patuakhali district.
