Data from: Combined measurements of prey availability explain habitat-selection in foraging seabirds
Understanding links between habitat characteristics and foraging efficiency help to predict how environmental change could influence populations of top-predators. This study examines whether measurements of prey (clupeids) availability varied over stratification gradients, and determined if any of t...

Understanding links between habitat characteristics and foraging efficiency help to predict how environmental change could influence populations of top-predators. This study examines whether measurements of prey (clupeids) availability varied over stratification gradients, and determined if any of those measurements coincided with aggregations of foraging seabirds (common guillemot Uria aalge, Manx shearwater Puffinus puffinus) in the Celtic Sea, UK. The probability of encountering foraging seabirds was highest around fronts between mixed and stratified water. Prey were denser and shallower in mixed water, and encounters with prey most frequent in stratified water. Therefore, no single measurement of increased prey availability coincided with the location of fronts. However, when considered in combination, overall prey availability was highest in these areas. These results show that top-predators may select foraging habitats by trading-off several elements of prey availability.
