Sierra Leone Tingi Hills
Sierra Leone Tern colony near Freetown
Over 640 bird species have been recorded in Sierra Leone of which over 430 are resident and over 130 are regular seasonal migrants including 90 Palearctic migrants. There are 23 species of global conservation concern. The forests of eastern Sierra Leone form the western part of the Upper Guinea forests Endemic Bird Area (EBA) and 14 of its 15 restricted range species occur in the country. Some 174 species of the Guinea-Congo forests biome and 28 of the Sudan-Guinea Savanna biome are known from Sierra Leone. The coastline forms part of the eastern Atlantic flyway for migrant waterbirds and is probably one of the major stop-over and wintering sites for many Palearctic waders along the coast of west Africa.
