Flamingos and Wetland Birds

Nature & Wildlife

Greater flamingos have become one of the Algarve's most iconic wildlife spectacles, with flocks of several hundred now regularly present in the region's coastal lagoons and salt pans between late summer and early spring. Once an occasional visitor, the flamingo has become an increasingly reliable resident as wetland habitats have been protected and as the species' Mediterranean breeding population has expanded.

The primary flamingo sites in the Algarve are the salt pans and shallow lagoons of the Ria Formosa, particularly around Olhao and Tavira, and the Castro Marim marshes near the Spanish border. The Salgados lagoon near Armacao de Pera and the Alvor estuary near Portimao also attract significant numbers. At peak times, typically between October and March, it is not unusual to see 300 or more flamingos feeding in a single location.

Flamingos feed by filtering algae, crustaceans and small invertebrates from the shallow water, using their distinctive downturned bills to sieve the mud. The carotenoid pigments in their crustacean prey give them their pink colour. They prefer water depths of 10 to 40 centimetres, which is why the Algarve's managed salt pans and tidal flats are so well suited to them.

Beyond flamingos, the Algarve's wetlands support a remarkable community of waterbirds. The purple swamphen, chosen as the symbol of the Ria Formosa Natural Park, is a large, striking rail with deep blue-purple plumage and a bright red bill. Once endangered in Portugal, it has recovered well and can be seen in reed-fringed channels throughout the Ria Formosa.

Spoonbills, with their distinctive spatulate bills, are increasingly common in the Algarve's wetlands. Small breeding colonies have become established, and the birds can be seen feeding in the salt pans alongside avocets, black-winged stilts and a variety of egrets and herons.

Winter brings large numbers of ducks and waders to the Algarve's wetlands. Wigeon, teal, shoveler and pintail gather on open water, while dunlin, sanderling, bar-tailed godwit, grey plover and redshank feed on the tidal mudflats. The Ria Formosa and Castro Marim marshes are both Important Bird Areas recognised by BirdLife International.

Viewing flamingos and wetland birds requires patience and binoculars, but not necessarily a great deal of effort. The salt pans visible from the EN125 road between Olhao and Tavira often hold flamingos that can be observed from the roadside. The visitor centre at Quinta de Marim provides hides and nature trails. Boat tours from Faro, Olhao and Tavira offer waterborne perspectives on the lagoon's birdlife.
