More than 500 egg-laying ducks have reportedly been poisoned and killed at a farm in Tanguar Haor, a Ramsar-listed wetland. The incident took place on a riverine island in Tahirpur. The affected farmer, Sujan Mia, son of Siraj Mia from Mandiyata village, discovered the mass deaths after returning to his farm at noon. Locals reported that Sujan had been guarding the farm overnight and found the ducks dead upon his return. He suspects three individuals from the village, known for poisoning wild migratory birds, might be responsible. However, the Upazila livestock officer stated that he had no prior knowledge of the incident.
