Summering in Eastern Spain

The three Yellow Legged Gulls equipped with GPS-GSM in Mallorca at the beginning of this summer decided to spend the summer in different places. As many tourists, however, they chose to spend the summer in North-Eastern Spain. One (green cyrcle) moved up to Zaragoza, a second one stayed in Mallorca (blue cyrcle) and a third spent the summer near Barcelona (red cyrcle). 

Soon will be time to decide where to spend the winter ..?!
