African River Martin - It breeds along the Congo River and its tributary, the Ubangi. It nests in burrows in sand banks, and appears to be common common within its restricted range, despite being caught in large numbers by the local population for food. It is migratory, wintering in coastal savannah in southern Gabon and the Republic of Congo. Many birds remain to breed in the wintering zones. This martin feeds on insects caught in the air and frequently walks on the ground rather than perching in trees. Due to a lack of detailed information about its population numbers, this species is classed as Data Deficient by the International Union for Conservation of Nature.
