Whale Tail at Dusk

Last evening at dusk, we went sailing with some family members on Kawaihae Bay, on the Kohala Coast of Hawaii's Big Island.  The winds were light, the ocean surface was calm, and the mood was peaceful.

We were escorted for awhile by several Humpback Whales.  The whales seemed to be in a placid mood as well.  We saw no breaches or other dramatic behaviors.  Instead, the huge cetaceans glided along near the boat, occasionally diving below the surface for a time and then reappearing to blow and breathe.  I snapped this photo of  one whale's tail just as as it began a dive.
