They were again seen in the Bay of Fundy in August. It seems that, for Wart, the Delaware Bay is some sort of milepost. Perhaps, she left Shackleton there on his own and he just got a bit confused. After all, he wasn't even a year old, and had only made the migration north once. Hopefully, now he knows how to get south in the winter and will make the trek north this spring.
Humpbacks calve every two years on average.
Here's hoping for some exciting right whale sightings.
