Habitat
These birds live in slimy estuaries, beaches, salty-water lagoons and sometimes further inland in slightly salty waters, both as a resident wintering-specie, migratory or in transit bird. They favour very shallow waters where they can stir the mud at the bottom.
They are customary visitors of wetlands and lagoon areas such as Fuente de Piedra (Málaga)
In Doñana, in their migratory flight, they can be seen in muddy-flats bordering the marshes. They are rare in winter.
They are included in the National List of Endangered Species, and their conservation status is ‘Special Interest’.
