Overview: Global climate change is having a major effect on northeast Atlantic ecosystems, with warm-water plankton and fish species rapidly advancing northwards as sea temperatures rise. Here, we present a unique dataset showing that recent sea surface warming has also triggered a species at the top of the food chain, the critically endangered Balearic Shearwater, to expand its migration range northwards by over 20% in pursuit of food. Up to a third of the world population of this rare Mediterranean seabird now visits UK waters annually, and early indications suggest that other seabirds are being affected in a similar fashion.
