Short summary
Subarctic climate changes may affect the foraging ecology of top predators. We studied the foraging characteristics of two diving seabirds: common (COMUs) and thick-billed murres (TBMUs). COMUs had smaller wing area, partly used deeper depths with more frequent wing strokes, and used higher trophic prey than TBMUs. The smaller wing of COMUs may facilitate swimming agility so that they can capture more mobile prey. These may lead to their different responses to local marine environmental changes.
