Bangladesh
Bangladesh occupies the vast Ganges–Brahmaputra–Meghna delta, one of the world's largest river systems. Its predominantly low-lying landscape is shaped by countless rivers, floodplains, wetlands and seasonally inundated agricultural areas. The southwest contains the Sundarbans, the world's largest mangrove forest, while the east rises into forested hills around Sylhet and Chittagong. The climate is tropical and strongly monsoonal, with hot, humid summers, seasonal flooding and frequent cyclones along the Bay of Bengal.
Overview
Bangladesh is particularly important for wetland, coastal and mangrove birds. The Sundarbans support specialties such as Masked Finfoot, Mangrove Pitta and Brown-winged Kingfisher, alongside numerous raptors and waterbirds. Vast wetlands in the northeast, especially Tanguar Haor and Hakaluki Haor, host major concentrations of wintering ducks, shorebirds and other waterbirds. Forests around Lawachara add hornbills, barbets and other Indo-Malayan species. Coastal mudflats are internationally important for migratory shorebirds, including threatened Spoon-billed Sandpiper. Birding tourism remains relatively limited, and reaching some wetlands and mangrove areas requires boats, local guides and careful logistical planning.
