The main targets for the day were the Slender-billed Gulls at the Bonanza Saltpans and the White-headed Ducks at the Laguna de Tarelo. It involved a long journey back through Sevilla and down the eastern side of the Guadalquivir river. There were a number of other sites in the area to visit if we found our targets early but, as happens, things did not go exactly to plan, although we did find both targets fairly easily.
The Slender-billed Gulls were on the saltpans and viewable from the main road just north of Bonanza. There were probably about forty in total and they were very easy to identify. The pinkish heads and long black bills showed well but their behaviour was also unusual. They stayed in tight groups and seemed to be involved in communal feeding. A rare and unusual gull and it was good to be able to get such clear views.
The White-headed Duck, probably eight to ten of them, were also where they were supposed to be on the Laguna de Tarelo but they were a long way off. You can just about identify them in the picture below.
