I just returned home from a great trip aboard the Pride of Bilbao. Few birds (although we saw 3 Great shearwaters), but nice views of whales and dolphins. Before taking the ferry, a short stop at the Farlington marshes near Portsmouth resulted in 4 c-ringed Icelandic Black-tailed godwits (probably all locally-ringed birds).
During the short stop in the harbour of Santurzi, I was very happy to find (totally unexpected, I even let my telescope in im cabin) 3 c-ringed Yellow-legged gulls, all from the project of Jon Hidalgo and Gorka Ocio (who was also present on board of the ship). Since I didn't have my telescope with me, so I could just take some pictures through my binoculars.
