Track of One of the Tagged Birds (IMAGE) European Geosciences Union Caption This diagram shows the study site and the track of one of the tagged birds from May 17-21, 2012. When the bird is flying from its base on Puffin Island, the points are relatively widely spaced. When it is sitting on the water, they are closely spaced and the movement is consistent with that of the traveling tide. The inset map shows the position of the study area within the Irish Sea and relative to Liverpool, which lies 70 km east of Puffin Island.
