Comparative foraging ecology of planktivorous auklets in relation to ocean physics and prey availability

Parakeet Auklet (aethia psittacula) Science Article 2


tested the hypothesis that the spatial distributions of foraging least, crested and parakeet auklets (aethia pusilla, A. cristatella and A. psittacula, respectively) in the shallow passes of the Aleutian Islands would be determined by physical mechanisms that control near-surface prey concentrations. We recorded currents using an Acoustic Doppler Current Profiler, volume scattering using 200 and 420 kHz scientific echosounders, and the numbers of foraging birds.
