The foraging ability of visual hunters depends critically on light conditions. Emperor penguins Aptenodytes forsteri are reported to be visual hunters, but breed and forage at high latitudes and are thus exposed to extreme changes in light conditions in the course of the year. We examined how light influenced the foraging ability of breeding emperor penguins using loggers in winter (n = 5) and spring (n = 4) 2005 (see doi:10.1594/PANGAEA.633713) at Pointe Géologie (66°...
