The Ria Formosa is one of the most beautiful and important wetlands of Portugal, featuring an extensive string of sandy barrier islands parallel to the coast protecting the interior of the ria from the sea and creating environmental conditions similar to an estuary. This system extends for almost 60 km between Ancão beach and Cacela Velha, with a very special biodiversity in which birds are of particular importance.
Every year more than 30,000 birds use the Ria Formosa during their migrations and in winter, making this wetland among the three most important wetlands in Portugal. Some species are of European importance because of their important breeding populations, including the Little Tern, the Pied Avocet and Audouin’s Gull. The wide diversity of habitats here leads to the occurrence of a great number of species, one of the highest in Portugal, especially waterfowl, including waders and ducks in particular and, in lesser numbers, herons.The Ria Formosa is also noted for the highest numbers of wintering Eurasian Wigeon and breeding Red-crested Pochard in Portugal. On the land areas several species of woodland passerines occur, as well as various raptors.
