Week Eight of our 26th Season
This all singing, all dancing week on the Silver Bank got off to a great start and our guests had no idea just how lucky they were when the very first whale we encountered turned out to be a singer! For almost all of our guests, this was the first time they had heard a Humpback whale sing and everyone was fascinated by the complexity and range of sounds produced by the lone male who was most likely searching for a mate. The Humpback’s song is usually around twenty five minutes long and some have been recorded singing it over and over for more than twenty four hours. Some singers will remain in one place while they sing, rising to the surface to breathe every 15 minutes or so and returning to the same spot, while others will slowly swim while they sing. With this whale we were able to float over the musical giant for two breath cycles before he moved on to serenade in a different area of the Bank.
The good fortune continued when the very next morning we encountered another not so common phenomenon, dancing whales! Although this season we have actually been very lucky to have encountered several sets of dancers, it is always a privilege to see this beautiful behavior between a male and female whale. More often than not, the female will lead the graceful dance while the male simply stays close by but on this occasion the male appeared to be posturing along with the female and at one point the female held motionless, head down in the water while the male circled around her. It was a stunningly beautiful show and one we will never forget.
As the week went on with beautiful sunshine and calm seas, the whale encounters heated up with four sightings of large rowdy groups. As the season goes by and many females start their journey back to the northern feeding grounds, the numbers of males fighting over potential mates increase and the rowdy groups this week were larger and more violent than before, providing us with some spectacular surface activity! It is an awe-inspiring sight to see eight fully grown male whales all come to the surface at once in a high-speed race to defend their position next to a female. As the whales surfaced we saw bubble streams, lunge breaches and tail breaches as displays of virility and strength. We were also lucky enough to see a behavior called the “S curve” which is when a whale moving at high speed suddenly throws out their pectoral fins, effectively “slamming on the brakes”, and maneuvers to displace a challenging whale from their position next to the female. During one rowdy group encounter this week, two whales actually slammed into each other, dorsal to dorsal as they surfaced only a hundred feet from one of the tenders! Watery battles like this can go on for hours and it is common to see bloody tubercles and damaged dorsal fins as evidence that the fight was going on a lot longer before we came across them!
With the beautiful singer, the graceful dancers and the excitement of the rowdy groups, the week was made even more perfect by in-water encounters with a mother and calf and a pair of sleeping whales. Our guests really couldn’t have wished for a better week out on the Silver Bank!
The Aquatic Adventures team hopes that you are as inspired as we are to help sustain the humpback whale population. Through our partnership with the Center for Coastal Studies, we are helping to gain critical information on these charismatic creatures, and to seek ways to protect and preserve them.
