Tail Lobbing from Excitement

Posted on by
Aloha,
Patience paid off for guests aboard our 10:00 Whale Watch on Wednesday. First of all, there were so many whales to watch that we had to choose where to go…and then when we chose a direction, the whales seemed to choose our boat as an object of interest. A pod of 5 humpbacks approached us, and we watched as one of them breached and then, as our onboard naturalist Brooke put it, “tail lobbed like CRAZY”. That must have prompted some excitement in the other whales (it sure got us excited), because one started pec slapping, and then two other whales surfaced right next to us multiple times – there came up so close that we could recognize them. We also watched multiple breaches in the near-by distance (not from our competitive pod) and then got to see a coalition of 5 other whales form. We thought this might turn into another competition, but we had to return to the bay before anything materialized.

Captain Claire’s Humpback Fact of the Day: Biopsy samples taken from South Pacific Humpbacks show a ratio of 2.4 males for every female on the breeding grounds. A similar ratio has been observed in Hawaii. This suggests either: 1). female Humpbacks can afford to be choosy with their mating partner; or; 2). female Humpbacks are overwhelmed by aggressive males and bullied into mating.

Very, very loud singing and some competition

Aloha,
We had an incredible Whale Watch at 10:00 on Tuesday. We saw 14 different Humpbacks, but spent considerable time watching a Mom, her baby and an escort trying to keep another huge male at bay. We saw 3 body lunges from this group, and 5 head lunges, plus 2 pectoral slaps and 4 peduncle throws. We also got to see Mom and baby up close as they swam right under us about 30 feet deep. We got to see right up their blow holes! When we deployed the hydrophone later in the trip, the songs were incredibly loud. The bass notes literally shook the boat…we could actually feel (and see) the windows vibrating. Oh — and we also saw a couple of breaches during the trip. It was a great couple of hours! On our 3:00 Whales and Cocktails, guests saw a total of 6 whales. According to our naturalist Angelica, the first whales spotted were way South of the Bay, and a good ways out to sea. We did find a pod of two whales much closer though, and spent considerable time watching them travel along the coast. They were in a 3-4 minute dive pattern, surfacing, spouting a couple of times and then sounding for those shorter dives. We got to see lots of flukes from this pair.
