Alderney’s Northern Gannet colonies are the second most southerly in the world and support around 1% of the species’ population. With many offshore wind farm sites proposed within the English Channel and with the possibility of tidal turbines being deployed in Alderney’s waters, it is more important than ever for us to understand where these magnificent birds are feeding. The information gained from the tags gave an unprecedented picture of the gannets’ life-cycle, feeding habits and the likelihood of their interaction with potential offshore wind farms and tidal developments.
To do this the AWT raises funds every year to purchase state-of-the-art experimental miniaturised GPS tracking devices which were placed on the birds' tail feathers by a team of scientists from the British Trust for Ornithology, Liverpool University and the AWT. The tags last around six weeks, which is ideal as we do not want these devices permanently attached to the birds.
