A day to ourselves so we went back to Foz do Arelho this time in the sun. Foz is located on a large lagoon and I spent quite a while trying to photograph the Sandwich Terns which were diving from a height into the pool at the end of the lagoon. I tried tracking the Terns individually and then I tried focussing on a particular spot but they were way too fast... this is the best of a large number of empty sky and water shots!
