Excerpt from Proceedings of the American Philosophical Society, Vol. 54: Held at Philadelphia for Promoting Useful Knowledge, 1915 The breeding habits of the Alaskan fur seals are so unusual as to make these animals unique among mammals. During much of the year, these seals are strictly pelagic roaming over the eastern expanse of the northern Pacific as far southward as the latitude of southern California. As summer approaches, practically the whole herd consisting of several hundreds of thousands of individuals repairs to the two small islands of St. George and St. Paul in Bering Sea for the breeding season. It is the relative proportions of the various constituents of the herd during this breeding period that affords material for interesting speculation. The movements of the fur seals in their arrival and departure from the Pribilof Islands take place with much regularity. Early in May and June the mature males or bulls, having made their way through the passes of the Aleutians, reach the breeding beaches or rookeries on the islands of St. George and St. Paul. Here they take their positions, fighting all intruders while they await the coming of the females or cows. The cows arrive on the islands chiefly during June and July. They associate themselves with particular bulls and the bull with his group of cows constitutes the family unit or harem.
