The BSF seized a pair of Keel-billed toucans near the Angrail border outpost in Bongaon, North 24-Parganas, on Thursday, an officer said.

Officers at the outpost along the India-Bangladesh border had received information that “foreign and expensive” birds would be moved to Bangladesh, S.S. Guleria, DIG, BSF (South Bengal Frontier) said.

Two men dropped a pack age near Halderpara village on seeing a BSF tea. “Wee took the birds... they have been handed over to Alipore zoo,” Guleria said.

A pair of the birds will cost around Rs 15-18 lakh, a bird lover said.
