Lower nutritional state and foraging success in an Arctic seabird despite behaviorally flexible responses to environmental change
The degree to which individuals adjust foraging behavior in response to environmental variability can impact foraging success, leading to downstream impacts on fitness and population dynamics. We examined the foraging flexibility, average daily energy expenditure, and foraging success of an ice-asso...
