Winter in Bangladesh brings migratory birds to various locations, ideal for birdwatchers. Key spots include Hakaluki Haor, Nijhum Dwip, Char Kukri Mukri, Baikka Beel, Chalan Beel, and Jahangirnagar University, where rare species thrive in the seasonal sanctuary.

Hakaluki Haor, one of the largest freshwater wetlands in Bangladesh, spanning five upazilas in Sylhet and Moulvibazar districts, was once a safe haven for migratory birds during winter.

Bangladesh is said to have about 712 species of birds although the IUCN Red List of Bangladesh confirmed about 570 species.

The number of migratory birds at Hakaluki Haor has been gradually decreasing over the last five years for a variety of reasons.

Several thousand birds, mostly migratory birds, are killed in 'Anurima Eco Park' in Narail’s Kalia upazila as hailstorm coupled with rain ripped through the country in last few days.

Energy companies and other businesses that accidentally kill migratory birds will no longer be criminally prosecuted, the Trump administration says in a decision hailed by industry but denounced by environmental groups.

Tangua haor is a mini ocean during monsoon. But in winter much of the water is gone and the haor turns into a maze of interconnected wetlands called beels. Once away from the muddy shores overgrown with reeds, one can see through the clear beel water a magnificent green carpet of plants at the bottom. This garden, hidden underneath the water, is visited by thousands of ducks during the winter months every year.

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