We investigated short-range orientation in king penguin (Aptenodytes patagonicus) chicks that live in large and densely populated colonies. In such colonies, navigation to specific locations can be challenging due to the presence of many conspecifics. Our objectives were 1) to determine if chicks displaced to a novel location away from the colony can return to their home location (crèche) and 2) to identify the environmental cues they use for orientation. To address this, we conducted experiments that involved displacement of chicks when the availability of visual, acoustic or magnetic cues was manipulated. The results suggest that visual and acoustic cues are important for chick’s orientation, but this is not the case for magnetic cues.
