It is not unusual to see several species of Skuas on the coast of Almeria, some are on passage and some, Bonxies (Stercorarius skua), winter in the area and can be seen among the gulls that follow the fishing boats in the evening. I found two recoveries of Bonxies while looking for any ringing data in Mojacar.
Both Bonxies were ringed in the Island of Foula in Shetland, UK, as chicks, and both were found dead on the beach in winter.
The first bird was ringed in Foula in July 1976 and was found dead in December 1989, the bird was 13 years old. The other bird was ringed in June 1995 and found dead in 1998, only 3 years old.
