Humpbacks south of Point Retreat

We spent some time in our boat after having not been on the water for well over a month.  I was anxious to see if there were any whales still in the area.  Unfortunately the water was very choppy and we were unable to go very far.  However, we did see six humpbacks while we were out.  I was able to identify four of them.  Three of them appeared to be together.  I was able to identify them as #1447, aka Juneauite and #2006, aka Magma.  Magma has a calf this year.  The third whale was a calf so I am assuming it was Magma's calf.  Last year on October 2, 2018, we encountered Magma and Juneauite as they logged very closely together at the surface of the water.  They seemed to be hanging out with one another much like this year's encounter.  It is amazing to me that they are able to find each other.  I cannot help but wonder if they are friends (if that is possible).  I identified the fourth whale as #1879, aka Sasha.  She was off on her own.  The other two whales were off in the distance closer to Point Retreat.  The water was too choppy to identify them.
