Species that can be observed only during the migratory passage in the province. Nest on the ground, among bushes. One laying of 4 eggs. It feeds on insects, small crustaceans and seeds.
It can be watched at the mouth of the Guadalhorce and at the Fuente de Piedra and Campillos lagoons.
Due to the size and shape of its bill, the Curlew Sandpiper has access to different food resources from the other sandpipers, since it can reach invertebrates buried deeper. This type of birds reaches distances of almost ten thousand kilometers (more than 6,000 miles) between their breeding and wintering areas.
