Sable Island NPR Grey Seal Count

The most populous vertebrate animal on Sable Island National Park Reserve is the grey seal. Winter is their breeding season, and approximately two hundred and fifty thousand seals roam the island and cover the shorelines. While the summer population is far less than that of the colder season, large herds of seals are still found along the shores of North and South beaches.
