The emperor penguin is a social animal in its nesting and its foraging behavior; birds hunting together may coordinate their diving and surfacing. Individuals may be active day or night. A mature adult travels throughout most of the year between the nesting area and ocean foraging areas; the species disperses into the oceans from January to March. | The emperor penguin is a social animal in its nesting and its foraging behavior; birds hunting together may coordinate their diving and surfacing.

Emperor penguins are able to breed at around three years of age, and usually commence breeding around one to three years later. The yearly reproductive cycle begins at the start of the Antarctic winter, in March and April, when all mature emperor penguins travel to colonial nesting areas, often walking 50 to 120 km (31 to 75 mi) inland from the edge of the [[pack ice]]. The start of travel appears to be triggered by decreasing day lengths; emperor penguins in captivity have been induced successfully into breeding by using lighting systems mimicking seasonal Antarctic day lengths. | Emperor penguins are able to breed at around three years of age, and usually commence breeding around one to three years later.
