Doñana National Park has a biodiversity that is unique in Europe, although there are some similarities to the Parc Naturel Régional de Camargue of the Camargue river delta in France, with which Doñana Park is twinned.
The park features a great variety of ecosystems and shelters wildlife including thousands of European and African migratory birds, fallow deer, Spanish red deer, wild boars, European badgers, Egyptian mongooses, and endangered species such as the Spanish imperial eagle and the Iberian lynx
