Where do penguins go during the inter-breeding period? Using geolocation to track the winter dispersion of the macaroni penguin
Although penguins are key marine predators from the Southern Ocean, their migratory behaviour during the inter-nesting period remains widely unknown. Here, we report for the first time, to our knowledge, the winter foraging movements and feeding habits of a penguin species by using geolocation senso...
