Species that appears on the coasts of the province only during its migratory passage. It breeds at the end of May in northern Europe, Lapland and Siberia. Nest on the ground. One annual laying of two to four eggs. The Bar-Tailed Godwit feeds on insects, worms, molluscs and crustaceans that it captures by exploring the mud with its bill deeper than other species of waders.
It is a relatively frequent bird, less than the Black-Tailed Godwit, and that can be observed in the mouths of the Vélez and Guadalhorce rivers and in the Fuente de Piedra lagoon. The migratory passage of this bird can also be watched at Punta de Calaburras.
Its popular name in Spanish ("aguja", which stands for "needle") refers to the needle shape, elongated and thin, of its bill. Its tail has a striping or barring that is the cause of its name ("bar-tailed"). The species makes one of the most amazing migratory trips that are known. It flies almost 11,000 km (nearly 7,000 mi, almost as from Alaska to New Zealand) without stopping. A trip that lasts eight days and which is guided by the earth's magnetic field and by the position of the stars.
