Three humpbacks near North Pass

We spent some time in our boat looking for whales and found three near North Pass.  The first whale was about 1/2 mile north of the pass.  It was traveling alone.  We did not spend much time watching it.  As we entered North Pass, I immediately spotted what looked like a mom and calf pair.  The calf was small and behaving like a young one.  It stayed very close to its mom.  It would surface a bit before she would, but would quickly rejoin her mom once she surfaced.  I had heard that Sasha #1879 was spotted in Maui with a calf, so I assumed it was the pair.  After a few dives, I was finally able to identify the mom.  It turned out to be Flame #1538.  I was shocked, as Flame had a calf with her last summer.  I reached out to a few people, and the thought was perhaps she was still with her calf, Bunsen, from last year.  The last few times I saw Flame last summer, Bunsen was nowhere to be found.  I also saw Flame on December 24, 2019, and Bunsen was not with her.  It did not make sense to me that she would be with Bunsen now.  I also have never seen Flame associating with other whales.  She might be in the same general area as other whales, but she is always off on her own.  I have always felt she is a loner. 
​After posting a photo of her on Facebook, someone mentioned that she had been spotted in Maui this past winter with a new calf!  It is a bit unusual for humpbacks to have a calf every year.  Generally it is every two to three years.  I hope to see them again soon.  It would be neat to confirm that it is indeed a new calf.
