The Tanji Bird Reserve, established in 1993, spans 612 hectares and is located in western Gambia, near the fishing village of Tanji. It includes a diverse range of habitats such as the Karinti River, coastal lagoons, and the Bijol Islands, which are vital for breeding marine turtles and roosting birds. The reserve is home to around 300 bird species, including 82 Palearctic migrants, and is recognized as an Important Bird Area by Birdlife International. It supports significant populations of shorebirds, seabirds, and Gambia's only breeding seabirds, including grey-headed gulls and royal terns. The reserve is also rich in insect life, with numerous unique termite species.
