Portugal
Portugal’s Tagus Estuary, Sado Estuary, and Ria Formosa are internationally recognized coastal wetlands hosting large numbers of migratory Black-tailed Godwits, Eurasian Curlew, and Greater Flamingos, alongside locally breeding species. These wetlands provide crucial staging and breeding grounds along the flyway’s western corridor. Conservation efforts emphasize maintaining water quality and reducing disturbance to support these waterbird assemblages.
