Long-Term Observations of a Harbor Seal Haul-Out Site in a Protected Cove in Casco Bay, Gulf of Maine
We counted the numbers of seals hauled out at low tide on two near-shore ledges in a protected cove in Casco Bay, Gulf of Maine a minimum of 12 times per month, for four years starting in August 1997. The highest mean monthly counts were in August (molting season) and the lowest in either January or...
