Double Breach…and One Whale Breaches 8 Times

Posted on by

Aloha,

Have you ever seen a double breach? Lucky guests aboard Tuesday’s Wake Up With the Whales Cruise on Seasmoke got to see this very exciting surface activity about midway through our cruise. We were watching Mom and her baby being chased by two male Humpbacks when all of a sudden Mom and one of the escorts breached simultaneously right next to some kayakers. The splash they created actually hid the kayakers from our view — we could only imagine what they must have been thinking when these big whales erupted out of the water together.After that, baby breached about 4 times, and head lunged a few more times. We also got a couple of very close encounters when Humpbacks decided to surface off our port stern. Our 10:00 Whale Watch on Alala started with a huge breach just after we had left the harbor. When a cruise starts that good, everything else we see just adds to the excitement. We found a very small calf on this cruise, swimming and diving down to Mom…and we also saw some tail lobbing from another adult Humpback. On our Whales and Cocktails Cruise out of Kawaihae, we got to see a Cow/Calf/Escort close to the boat, but the grand finale was watching a big adult Humpback breach 8 times!

Captain Claire’s Humpback Fact of the Day: Researchers off the coast of Brazil have discovered that some marine mammals including Humpbacks may have up to 14 spleens. Among other functions, the spleen stores red blood cells (which store oxygen)…so an extra spleen may help a deep diving animal stay underwater longer. These spleens can contract during a dive, releasing fresh blood with oxygenated red blood cells to keep the whale’s important organs alive and functioning. 14 spleens?! Amazing.

Singing and Breaching

Aloha,

We started out the week with a double boat Wake Up with the Whales. Both Manu Iwa and Seasmoke departed from Anaeho’omalu Bay at around the same time, so you’d think all of us would have had the same experience. But of course, we didn’t…guests aboard both boats saw spouts from more than 2 dozen whales, but Captain Jeff chose to take Seasmoke out to a competitive pod about a mile outside of the Hilton. We got to see some great peduncle throws and a couple of pec slaps and tail lobs from this pod of 3. We then found two different Mom/Baby/Escort pods. Captain Will took Manu Iwa to the south, and guests also got to spend some quality time with a Mom/Baby/Escort pod. Lots of whales around the boat were breaching — they weren’t super close, but we definitely got to see more than just the splash. And when each boat deployed our hydrophone, we got to hear some very clear and loud singing.
By the time we departed for the Whales and Cocktails Cruise, the wind had come up. We only were able to stay out for an hour, but we got to see 13 different whales (or splashes from the whales). As is usual on a very windy ocean there was lots of breaching, peduncle throwing and tail lobbing going on. Even though we saw a lot and it was really pretty exciting, since we did have to come in early we invited our guests to come back again for no charge.

Captain Claire’s Humpback Whale Fact of the Day: Most Humpbacks are “right-handed”. Researchers looking at abrasions on Humpbacks’ jaws found more abrasions on the right jaw than on the left, and observed more “flippering” with the right flipper than with the left, suggesting a definite right-side preference among the Humpback population.

 

When a Mugging is a Good Thing

Aloha,

We had a great weekend of whale watching. With so many cruises, there’s no way I can recap everything, but here are a few highlights. On Friday’s Wake up With the Whales Cruise on Seasmoke, we got to watch a pod of three whales twisting and turning around each other on the surface. For awhile, two of them were obviously belly to belly and then one was on top of the other — were they mating? On the Whales and Cocktails Cruise on Manu Iwa, we saw two different Mom/Baby/Escort pods. One of the escorts breached three times when he was just 30 feet from our idling boat. We also got mugged by the second pod for more than 30 minutes. All day long, we were seeing whale spouts in every direction.
On Saturday’s 8:00 am Cruise from Anaeho’omalu Bay, Captain Jake had a choice to make when we left the bay. We saw spouts in pretty much every direction, but we went south, and it paid off. We spent most of our time with a competitive pod of 4 whales who were charging around on the surface. We got to see the differences between the shapes of their flukes…and also got to see a bit of a fight. The whales didn’t seem to care that we were idling in the area as they milled about, changing directions, and even surfacing about 30 feet from us and charging towards us before diving. We also saw a whale from a different pod tail-lob 13 times before tiring out, and lots of lunges and peduncle throws from whales further in the distance. On the 12:30 Cruise, lucky guests got to see a whale breach 15 times right in front of the boat, and on the Whales and Cocktails, we were mugged for a good ten minutes by two curious whales who kept surfacing  just 10 feet away from our idling boat.
On each of Sunday’s cruises we saw spouts from more than 2 dozen Humpbacks. On Manu Iwa’s 8:00 Wake up with the Whales Cruise, we all enjoyed the antics of several different calves, but we were totally blown away when one baby approached the boat at the end of the charter. Not only did mom let him come within about 50 feet of us, but she surfaced too…and then one of our guests on the starboard bow noticed a shadow in the water. It turned out to be the escort who cruised under us just 10 feet below the surface. We all got a great look at him as he passed below the hulls. On our special 11:00 Educational Cruise, the Girl Scouts from Ke’eau, and some high school kids from HPA got to see lots of breaching, peduncle throwing and tail lobbing from some very energetic adult whales. We also got to see a couple of yearlings close up when they cruised by our idling boat.
Hope your weekend was as nice as ours!

Captain Claire’s Humpback Fact of the Day: According to research conducted by the Nelson Institute of Marine Research, a Humpback’s heart beats an average of 40 bpm, but the whales do experience periods of tachycardia and bradycardia (faster than normal and slower than normal heart rates) during dives.

Spy Hops!

Aloha,
We had a great day on the water on Thursday. With five different cruises just for Whale Watching, plus a couple of Snorkel Cruises thrown in, there’s way too much to report for one email, so I’ll just give you a few highlights. Though the surf was up today, the wind was very, very calm, allowing us to see for miles. There were lots of Humpbacks visible all day long — on our Wake up With the Whales Cruises (we took both Seasmoke and Manu Iwa out), we all saw a few breaches and lots of great fluke dives. On our Kid’s Educational Whale Watch Cruise, the kids (and parents and teachers from Wai’aha International Family School) got to see 3 spy hops about 100 yards from the boat. We also saw a pretty big peduncle throw. On our Whales and Cocktails Cruise we had several close encounters with adult Humpbacks, and when we stopped the boat we could actually hear the whales singing through the hulls. After we were serenaded for several minutes, we decided to deploy the hydrophone and our close-by singer was certainly the star of the show. He was making some groaning, clicking, and squealing sounds that were new to us (along with the “whooop, whoop, whoooooop” sounds we were familiar with from last year. The best part was when the singing stopped briefly. We knew he was on the way up, and he surfaced just 50 yards from us!
Mahalo and have a great weekend. I’ll send out a recap on Monday.

Captain Claire’s Humpback Fact of the Day: Yesterday, I mentioned that researchers estimated a Humpback’s daily fish consumption during the summer season to be on the order of 2000 pounds per day. And if you do a quick Google search you’ll find that “fact” cited all over the place. Turns out that this may be just another example of how inaccurate information gets spread. Once a “fact” is listed in a book, it’s picked up on the internet and its spread can be exponential.

According to researcher Briana H. Witteveen and her colleagues who conducted a study to determine the effect of Humpback predation on fish abundance near Kodiak Alaska, based on the documented stomach contents of Humpbacks “processed” through whaling stations back in 1937, combined with estimates of actual suitable prey availability, an average size Humpback whale is eating more on the order of 800 pounds (or about 576,000 calories) of food each day.Does that seem like a lot of food to you?

 

Magical Cruise with Dolphins and Humpbacks

Posted on by

Aloha,

Wednesday morning’s Wake Up with the Whales on Manu Iwa was a magical cruise. Not only did we see our first whales before we had even left the mooring (spouting just outside of the bay), but as we left the bay, we encountered two other Humpbacks even closer to shore than our first whales. The whole cruise was like that..whale after whale after whale. There really wasn’t a time when we weren’t seeing a dorsal fin, tail, or spout for the entire two hours. When we deployed the hydrophone, we heard lots of singing too. And if that weren’t good enough, Captain Will spotted a pod of about 20 Bottlenose Dolphins (pretty rare for us to see). AND, the dolphins swam over to us, AND several of them spent a good half hour jumping over the whales. It really looked like something you’d see at Sea World when those dolphins were performing perfect arcuate leaps over the whales. We also saw some pec slapping, lots of fluke dives, and were approached within about 30 feet by a baby whale who just had to get a look at us. Mom was pretty relaxed about it, letting baby turn towards us and swim alongside the starboard hull before she came up underneath her calf, lifted him a little with her rostrum, and pushed him gently away from us. On the Whales and Cocktails Cruise, we also saw lots of Humpbacks. They were all pretty quiet, surfacing just to spout and dive, but we did see a few pec slaps. The highlight of this cruise was a toss-up…we got to see Mom/Baby and a HUGE escort pretty close up. We were idling when baby decided to come check us out which was really exciting…but we also got a close-up visit by two big adult humpbacks.

Captain Claire’s Humpback Whale Fact of the Day: Researchers report that Humpbacks in Alaska can consume a ton of food in a day. Their diet consists mainly of very small fish like herring, capelin, sand lance and krill. Based on the calorie count of herring, a Humpback in Alaska is consuming 1,500,000 calories each day!

Playful Calves

Aloha,

Tuesday morning was a great time to be on the water on the Kohala Coast! We took out two boats for our Wake Up with the Whales Cruise from Anaeho’omalu Bay, and though we went different directions, guests on both cruises got to see a wide variety of surface behaviors from Humpbacks of all ages. On the Manu Iwa, we saw 25 different Humpbacks, including one Cow/Calf/Escort pod with a very active little calf. This guy did several tail lobs (which are really cute when you see a calf do them). We also got to see some whales that appeared to be as long as our boat (50′) — including one who surfaced about 25 yards from our idling boat, and then came up to get an even closer look. On Seasmoke, we also saw more than 20 different Humpbacks within 3/4 of a mile. We spent a considerable amount of time at idle, watching a Mom/Baby/Escort. We knew baby was pretty young because he still had a bent over dorsal fin. Mom looked to be pretty young herself (she was only about 35 feet long). Our second Mom/Baby/Escort pod came across us a little later in the cruise. Baby breached 5 times very close by (he kept trying to get closer), and we all got a great view of his ventral pleats (the “lines” we see on his belly). We also had several close encounters with solo whales who surfaced very close by at different times throughout the cruise.

Captain Claire’s Humpback Fact of the Day: We’ve never witnessed a Humpback taking care of two calves. We know she could conceive twins (and whalers occasionally would find twin fetuses) but we doubt she could carry twins to term. And even if she could, we really doubt she could produce the 200 gallons of milk she’d need each day to feed two calves!

Swell time Despite the Swell

Posted on by

Aloha,

Well the surf that came up on Thursday decided to stick around for most of the weekend, so we were forced to cancel a lot of our Whale Watch Cruises. But on the few cruises we did take out, it seemed that the whales were as happy to see us as we were to see them. For instance, on Saturday’s Wake Up with the Whales Cruise on Seasmoke from Anaeho’omalu Bay, we got to see 7 breaches. But that wasn’t all. It seemed like no matter which way we looked, there was something going on at the surface — peduncle throws, tail lobs, pectoral slaps. Perhaps the best of all though, was when we found ourselves the object of interest for a Mom and her calf who decided to surface right next to us while we were all looking the other way. By Sunday’s Whales and Cocktails Cruise, we had some wind along with the swell, but we still got to see Mom and calf, and we also got to see a lone adult cruising along the surface.

Captain Claire’s Humpback Fact of the Day: A distinguishing morphological (body) characteristic of the Humpback is the length of her pectoral fins. Their average length is 1/3rd the length of the Humpback’s body (approx. 15 feet). The genus name for the Humpback (Megaptera) describes the fin – the translation from Latin for Megaptera is “Big – Winged”)

Does Big Surf Affect the Humpbacks?

Posted on by

Aloha,

As predicted, the surf was HUGE on the west side of the island on Thursday, causing us to cancel all of our charters. Since the closer to shore you get, the more you feel the water movement, it made me wonder how the Humpbacks handle high surf days. Do they move out to sea to avoid the surge?
Throughout my career as a whale naturalist, I’ve been on lots of cruises where the swell has been up. Though I’ve never been officially involved in a study tracking the movement of the whales, I have noticed anecdotally that we have to go further from shore to find the Humpbacks on big surf days. But those observations aren’t scientifically valid ones.
So, I spent some time looking through published research to see if anyone else has observed and documented this correlation.
A scan of the literature didn’t help me much with this question…but I did find recently published research that found that calves are more likely to play around on the surface when it’s rough than when it’s calm (they may get excited by all the wave action and want to see what it feels like)…and that male calves surface without mom more frequently than female calves, and stay on the surface longer. Since surface play may help to build muscles and increase myoglobin (which helps with oxygen storage so the whales can go longer between breaths), these young males might actually be preparing themselves for the different social life they’ll live when they grow up.
I also found other recently published research where the researchers found that Humpbacks switched from primarily vocal to primarily surface generated communication (breaching/peduncle throwing etc) in rougher oceans — they posited that the sound from a big splash travels across greater frequencies and therefore might be more easily detected by other Humpbacks in a noisy environment.
I’m still searching for research about whether Humpbacks are affected by the surf…if you find anything, please send it my way!
Have a great weekend. I’ll send out our Weekend Recap on Monday.

Delicious, Nutritious Humpback Whale Milk

Posted on by

Aloha,

We started out our Wednesday with some excellent sightings on both Manu Iwa and Seasmoke for our Wake Up with the Whales Cruise. On Manu Iwa, we saw more than 20 Humpbacks within a mile from us, but many of them were much closer. We got to see a Mom and her baby unaccompanied by an escort. Baby breached a few times (probably burning off some of the energy he gains from drinking all that milk). We also saw a few HUGE (45 foot plus) whales — one of whom surfaced within 20 feet of us while we were idling with the hydrophone in the water. And speaking of the hydrophone — we heard a whole symphony when we deployed it today. While all this was going on, we also saw peduncle throws, and lots of pectoral slaps. Since Seasmoke departed at the same time from the same location, we decided to look for our “own” whales, and boy, did we find them! We watched a calf and his Mom for awhile, before another whale surfaced less than 100 feet from us. We actually didn’t know which way to look for a lot of the charter since there were whales everywhere! We saw lots of pec slaps, breaches, and peduncle throws, and also heard some pretty clear singing when we deployed our hydrophone.
On our 10:00 Cruise from Kawaihae, we found a Mom/Calf pod just north of the harbor. We watched them for awhile and got to see baby breach before we headed off to watch some of the other bigger whales we were seeing out a bit further. We came across a competitive pod of 5 whales who were doing their usual competitive aggressive behaviors — head lunging, peduncle throwing, and bubble blowing. At one point, they all passed within about 50 feet of our idling boat. On the way back to the harbor, we found our Mom and baby again. We stopped to watch baby breach 8 more times…but had to head back to the dock. As we left (which it was just killing us to do, but we had to get back), we watched baby continuing to breach over and over and over again.

Captain Claire’s Humpback Fact of the Day: Being mammals, Humpback Moms feed their calves milk. But Humpback milk isn’t just any old milk — it’s extremely rich with a fat content of approximately 50%! Human milk contains only about 4.5% fat. Supposedly, Humpback milk tastes like “sweetened cod liver oil” …but I don’t know that from experience!
