African penguins are marine and usually found within 40 kilometers of the coast, coming ashore on islands or at non-contiguous areas of the mainland coast to breed, moult, and rest.
They usually feed within 20 kilometers of the colony, when breeding, although at some colonies the distance is greater.
They can remain out at sea for up to four months at a time.
