Note 59 — THE MIGRATIONS OF MAMMALS.
Margaret R. Thomson translation
[Note 59] p. 250.—Migrations of Seals.
Much interesting information as to the migrations and habits of seals will be found in J. A. Allen’s History of North American Pinnipedia. The eared fur-seals (Otaria) and others travel periodically to the breeding-places or “rookeries”, where they spend a considerable time, but it should be noted that our common seal (Phoca vitulina) does not make seasonal migrations.
