To forage optimally, predators face complex decisions regarding target prey distribution, quantity, and quality. We paired theodolite tracking of gray whales Eschrichtius robustus in Port Orford, Oregon, USA, with concurrent sampling of their zooplankton prey to examine foraging decisions relative to prey quantity (abundance) and quality (caloric c...
In this study, behavioral plasticity in harbor seals was investigated in spatial reversal learning tasks of varying complexities. We started with a classic spatial reversal learning experiment with no more than one reversal per day. The seals quickly learned the task and showed progressive improvement over reversals, one seal even reaching one-tria...
Predators must consume enough prey to support costly events, such as reproduction. Meeting high energetic requirements is particularly challenging for migrating baleen whales as their feeding seasons are typically restricted to a limited temporal window and marine prey are notoriously patchy. We assessed the energetic value of the six most common n...
