Parc National du Diawling in the lower delta of the River Senegal is an important collecting and breeding ground for waterfowl. Together with the Senegalese part of the delta, where the Parc National des Oiseaux du Djoudj is situated, this area provides an important feeding and watering site for numerous Palearctic migrants. The mangrove swamp supports breeding colonies of Purple Heron Ardea purpurea, Black-crowned Night Heron Nycticorax nycticorax, African Spoonbill Platalea alba, Great Cormorant Phalacrocorax carbo and Great White Pelican Pelecanus onocrotalus. Small numbers of bustards, guineafowl and francolins are present.
