I wouldn't attribute any single source to the apparent demise fo the
whales. Things tend to run in cycles and all of the outside problems
don't help much.

I'm not qualified to answer this part of the question however, whales of
all types periodically enter bays and estuaries. We see it happen in the
St. Lawrence River Estuary and even in Boston Harbour.
