Chinstrap penguins alter foraging and diving behaviour in response to krill size
changes in prey availability. Chinstrap penguins are dependent predators of Antarctic krill in the Scotia ... Sea region. Both the sizes of krill found in penguin diets and acoustic estimates of krill biomass ... have fluctuated in recent years. We therefore examined the diet of chinstrap penguins at Livingston ... shift to deep dives after sundown, and then resumed their shallower pattern at sunrise. These nighttime ...
