BLACK-BROWED ALBATROSSES FORAGING ON ANTARCTIC KRILL: DENSITY-DEPENDENCE THROUGH LOCAL ENHANCEMENT?

Black-browed Albatross (Thalassarche melanophris) Science Article 5

abstract

Many Antarctic seabirds depend on prey that are patchy, cryptic, ephemeral, and unpredictable in location. These predators typically employ two alternative behavioralstrategies for locating resource patches: direct visual or olfactory detection, and indirect detection (local enhancement) by sighting other predators that are already exploiting a patch.
