Though the species appears to be capable of travelling long distances over ice, it doesn't seem well adapted to such an environment. Breeding occurs on rocky beaches sheltered from the sea. The islands they inhabit commonly support lush grass growth inland. During the months of May and November, there is a general movement out to sea, but specific migration paths are unknown. Some adult males are found ashore or in the general area of the breeding islands year-round.
