Short summary
We investigated how the largest seabird of the North Atlantic, the northern gannet, uses the southern North Sea as its habitat to search for food. We deployed small GPS trackers on the birds that recorded the birds' movements in detail. Birds were away from the breeding colony mostly for 1–15 h and up to 80 km distance to find prey for their chicks and themselves. To obtain food, they dove frequently to depths of 1–3 m, with a maximum of 11 m.
