We used a tracking dataset spanning over 20 years to quantify inter-annual and sub-colony variation in the foraging distribution of breeding European shags. We were also able to assess the duration of study required to adequately capture the population foraging distribution, and to identify intrinsic and extrinsic determinants of foraging range.

Our results highlight the value of long-term tracking studies in assessing the consistency of area usage over time. They also demonstrate the importance of considering the prevailing conditions experienced by the study animals and the representativeness of the sample of the population studied.
