Calm Ocean = Calm Whales

Aloha,
The ocean was so calm on Tuesday, and the skies overcast, so it felt as if we were cruising on a silvery mirror. The whales seemed pretty calmed by it all too. In the morning, all three of our catamarans went out for a two hour whale watch out of Kawaihae Harbor. Guests on Manu Iwa began their trip with a pod of Spinner Dolphins near Black Point. These dolphins were mostly swimming along the surface but we did see a few phenomenal spinning flips from a juvenile in the pod. We spent most of our Whale Watch time sitting near a pod of three big adults. Based on their behavior, we were guessing it was two males pursuing a female. We saw 4 pec slaps from the whale in front, and a couple of little tail lobs (we think this was the female).For awhile, when the two males were within touching distance of her, we saw her pick up her speed and even lift her chin out of the water. We saw some bubble blowing from the male closest to her (an aggressive move meant to block the other male). Towards the end of the cruise, we found a Mom/Baby/Escort pod. The adults in this pod were notably smaller than the three we had spent most of the day watching. Baby surfaced a few times, and we got to see him do a 360 degree roll down Mom’s rostrum. When we deployed the hydrophone, we heard a symphony of whales –  and at least two of them sounded pretty close by.

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 40bpm, but the whales do experience periods of tachycardia and bradycardia during dives. 

A Breach To End All Breaches

Aloha,
The winds calmed down on Monday allowing for some great whale watching! On our Breakfast with the Whales Cruise, we saw one incredible breach (and lots of other breaching a bit further away). We also saw two different Mom/Baby pods – both accompanied by escorts. One of the babies was curious about us and swam right up to us for a look. On our 10:00 Whale Watch, it seemed to us that the whales wanted to rest. We saw lots of spouts, lots of peduncle arches (the posture that gives the whales their common name “Humpback”) and lots of flukes. At 12:30, everyone woke up again. We had a close encounter with a Mom and her Baby for just about 20 minutes. These whales seemed to enjoy us as much as we were enjoying them. And then, towards the end of the cruise, we found a competitive pod who came within 200 yards of us. They were really aggressive towards each other – and we actually got to watch one whale swim right up on top of another one, kind of sinking him and shoving him at the same time. And if that wasn’t enough, just before we got back to the bay, we found a pod of Spinner Dolphins! And on our Whales and Cocktails Cruise, we were all watching whales on one side of the boat when we got a surprise visit from a Mom and calf who then decided to stay right with us for about 20 minutes. After they left, we found a competitive pod who were head lunging and charging. And then…out of nowhere, we were all surprised when a BIG whale decided to do a full breach just about 50 yards from the boat. As Captain Will reports…it was just “FANTASTIC”.

Captain Claire’s Humpback Whale Fact of the Day: Before whaling was banned internationally, Humpback whales’ livers were processed for their oil, which contained a lot of vitamin A. A fully grown Humpback has a liver that weighs between 800 and 1400 pounds.

Lots of Tri-Pods

Aloha,
We can certainly tell by our weekend of whale watching that it’s the beginning of March! This is the part of the season for us when traditionally, we see the highest proportion of pods consisting of Mom/Baby/Escort, and also when we see lots of competitive pods. We ran a lot of whale watches these past few days, so I’ll just list some of the highlights.
On Friday’s Breakfast with the Whales, we saw more than two dozen different whales, but we focused our attention on three different Mom/Baby/Escort pods. We got to watch some pretty cute acrobatics from a couple of different babies who seemed to think that rolling around on Mom’s rostrum was a good way to spend the morning. We had 4 very close encounters on that trip with different pods…and to top it off, we got to watch a pod of Spinner Dolphins towards the end of our cruise, right outside of the Bay.
On Saturday’s Breakfast with the Whales, we started seeing whales before we even got on the boat! Two whales just outside of the bay were breaching and peduncle throwing multiple times while our guests boarded. And once aboard, we found 4 different competitive pods, and we saw breaching, tail lobs and peduncle throws from two of the pods. The other two pods seemed very intent on the chase. We also found two Mom/baby/escort pods.
And on Sunday, guests aboard our Breakfast with the Whales started the cruise with a pod of Spinner Dolphins just outside of the bay. We also saw 4 different Mom/Baby/Escort pods, a couple of fantastic breaches, and some very energetic tail lobbing and peduncle throws.

Captain Claire’s Humpback Fact of the Day:Though measuring the length and weight of a Humpback’s internal organs is not really an exact science, it’s been estimated that the intestines of a fully grown Humpback whale are about 200 feet long (approximately 5 times the length of her body).

Humpback Calf Adopts our Boat

Aloha,
Guests aboard our 10:00 Whale Watch on Alala had an interesting experience on Tuesday.  Just as we left the harbor, we found a pod of Spinner Dolphins, which is always fun…but we continued south and found a Humpback calf at the surface. The calf approached the boat and actually started rubbing up against our hulls! It looked like he was scratching some itchy skin on his sides and on his back, and as we got a better and better look at him, we noticed a chunk missing from his dorsal fin, and all sorts of other scratches on his body. Our on-board naturalist Mike had just finished telling everyone about the importance of the relationship between baby and Mom…and when Mom didn’t surface for awhile, we started to get worried. This little calf stayed right alongside the boat for 20, then 30, then 35 minutes…and just when we were all about to cry, thinking the baby had been abandoned (and also about to call the folks at the Hawaii Islands Humpback National Marine Sanctuary to report the situation), Mom surfaced and led our little friend away! A very happy ending to a very interesting whale watch.

Captain Claire’s Humpback Whale Fact of the Day:  According to research reported by the Keiki Kohola Project, the most common surface behavior observed of calves is “twirling” thru 360 degrees at the surface. These twirls often incorporate pec slaps and waves, and tail slaps and swishes. The researchers theorize all this movement not only helps the calves to improve their coordination, but also helps with the production of the intra-muscular oxygen-storing protein called myoglobin, allowing these calves the ability to stay underwater for increased amounts of time without breathing.

Muggings and More

Aloha,
Friday brought us some heavy winds so we only ran a couple of Whale Watch Charters. On the Breakfast with the Whales, we saw lots of surface activities, but the highlight of the trip was our close encounter with a Mom and her Baby who were curious enough to swim by and check us out. On the 10:00 Whale Watch, we saw 15 different Humpbacks including 4 Mom/Baby pods, three of whom were accompanied by an escort. We also saw 3 different species of dolphins – Spinners, Bottlenose, and Spotted.
The winds calmed a bit on Saturday and we had some great sightings. On the 10:00 Whale Watch, we stopped counting at 23 whales. The highlight of the trip was watching a competitive pod of 5 whales really charging each other. At one point we all watched as one of the males literally swam right over another male on the surface. We saw peduncle throws, tail lobs, and head lunges from this group too. On the Whales & Cocktails Cruise, both Seasmoke and Manu Iwa were mugged by a very curious whale. First, the whale spent 35 minutes right next to Seasmoke, and then he swam over to Manu Iwa and stayed for another 25 minutes. It was unreal! We also saw head lunges, breaches, tail lobs, and pec slaps but our memories of exactly how many of each of those activities we saw were erased after the muggings! If you’d like to see photos from this incredible cruise, go to the Hawaii Ocean Sports Fan Page on Facebook.
On Sunday’s 10:00 Whale Watch, guests saw 20 whales including 5 Cow/Calf/Escort pods. We saw lots of surface activity too, including 5 breaches, 10 tail lobs, a couple of peduncle throws and lots of pec slaps. At one point we found ourselves surrounded by 4 different Mom/Baby pods..one on each side of the boat, one at the bow, and one at the stern. And on the Whales & Cocktails Cruise, we saw 35 different whales…there was so much surface activity that we couldn’t keep accurate counts! We loved watching a very active baby whale breaching, tail lobbing, and pec slapping right along side his mom who was doing the same activities! We also loved watching a different calf ride along on top of her Mom’s rostrum…and another highlight was watching yet another calf lying on his back, double pec slapping. This was another one of those whale watches that had action every where you looked and every time you looked. I hate to keep using exclamation marks but I can’t figure out a better way to describe what we were seeing this weekend than by doing this!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Captain Claire’s Humpback 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.

Surrounded by Dolphins…and Whales

Aloha,
There’s all sorts of stuff to tell you about Thursday’s Whale Watches, because we saw all sorts of really interesting activity. On the 10:00 Whale Watch, we saw 33 different whales…no calves though. We really didn’t have to travel far – we saw whales just outside the harbor and then continued to see them no matter which direction we were looking. We did see quite a few breaches a couple of miles out, but we were so interested in watching our close-by whales that we didn’t go out to see the breachers. When we dropped the hydrophone, it sounded like the whales were singing directly into the microphone. We went out again at 12:30 and this time, we saw 28 different whales. We watched a sub-adult pec slap 18 times, then roll over and slap some more. After diving for a few minutes he came up and started slapping again. This whale was accompanied by another whale and from our vantage point, it sure look like the other guy was getting slapped. This second whale did take his revenge and shoved the pec slapper with his rostrum a few times. We also saw quite a few tail lobs and had several close encounters. The hydrophone on this trip also let us hear some very clear sounds. On the Whales and Cocktails Cruise, we saw all sorts of breaching but the last 40 minutes were absolutely incredible. Our boat was actually circled by a pod of Spinner Dolphins accompanying a Mom/Baby duo, while a couple of other adults (we assume they were males) breached around us. So incredible!
Mahalo and have a Great Weekend. I’ll send out the next report on Monday.

Captain Claire’s Humpback Fact of the Day: Humpback whales have 52-54 vertebrae, of which 42 are articulating (jointed) and 10 are fused forming the sacrum. Humans usually have 33 vertebrae, of which 24 are articulating and 9 fused forming our sacrums.

Incredible Breaches

Aloha,
Well, the weather mellowed out on Wednesday, but the Whale Watching was anything but mellow! On our 10:00 Whale Watch from Kawaihae, we saw a total of 15 whales. We saw 8 breaches, and 6 of them were from one whale who was just 25 yards from the boat. Talk about exciting! We also saw 3 pods of Mom/Baby, and one more Mom/Baby pod with an escort. One of these little guys was pretty excited too, and we got to see him tail lob 5 times and head lunge 2 times. When an adult is doing either of those activities, it’s usually interpreted as aggressive behavior, but when a calf does it, it’s just cute. We also saw 2 pec slaps from a different calf. When we deployed the hydrophone, we heard some nice clear sounds. And to top it off, we also encountered a pod of spinner dolphins! On the Whales and Cocktails Cruise from Anaeho’omalu Bay, we saw lots of nice fluke dives, but the highlight of the trip was definitely the sounds we heard when we dropped our hydrophone into the water. We did it twice, and the first time the singer was really close by, so we heard some great details.

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

A Weekend of Wild Activity

Aloha,
Guests aboard our Friday Breakfast with the Whales Cruise saw lots of whales, lots of spouts, and lots of tail lobs. The highlight of the trip was encountering a competitive pod that included Mom and her calf. We watched as Mom did her best to shield her calf from the fray…Mom is able to get pregnant right after she gives birth, but she rarely does. We’re not sure if it’s because she successfully avoids mating or if it’s because due to hormone levels affected by lactation, it’s actually more difficult for her to get pregnant while she’s nursing. On the 10:00 Whale Watch, we counted 22 different whales including a competitive pod of 5, one pod of cow-calf, and one pod of cow-calf-escort. We think it was the escort that gave us the highlight of this trip when he breached just 30 yards from the port side of the boat! We also saw 3 other breaches and 3 head lunges, and heard some great singing through our hydrophone. And we finished off our Friday by watching a competitive pod of 7 whales on our Whales and Cocktails Cruise. As usual, they provided lots of action on the surface…during the course of this cruise, we saw a total of 10 whales within a half mile of the bay.
On Saturday’s Breakfast with the Whales, we found a mom and her sleepy baby just outside of the bay. We watched them for awhile before finding a competitive pod of 3 whales. At one point, one of the whales swam under the boat, turned around and then surfaced right next to the boat, covering us with his spout. On the 10:00 Whale Watch, we saw 18 whales including one competitive pod of 6 whales, one mom-baby pod, and one mom-baby-escort pod. Highlights included one huge peduncle throw, and several head lunges, tail lobs and pec slaps. We also encountered a pod of spinner dolphins.
Sunday’s Whale Watches brought us more fun.Guests aboard our Breakfast with the Whales Cruise saw 5 different competitive pods…and 4 pods of Mom and Bay (one with an escort). We saw lots of breaching in the distance, a few pec slaps and some tail lobs too. On the 10:00 Whale Watch we saw 22 whales including a competitive pod of 6 (that performed 5 head lunges) and 3 different Mom/Baby pods (only one with an escort). And the day ended with sightings of 20 different whales on the Whales and Cocktails Cruise. Among other things, we saw breaches, and watched two BIG adult whales alternate tail lobs for about 10 minutes!

Captain Claire’s Humpback Whale Fact of the Day:   Just how difficult is it for a 40 ton, 45 foot long animal to “fly” from the sea in a total breach? Observers have reported seeing Humpbacks breach after only two kick strokes for propulsion. Based on the formula for calculating horsepower, measurements of laminar flow around cetacean skin (how water flows past the skin of the animal), girth, and drag in the water, the breaching whale is producing between 1500 and 1700 horsepower in order to “catch air”. We used to think it was closer to 5000 horsepower, but with the aid of a calculator and more accurate measurements, we’ve been able to recalculate more accurately…still, try this yourself next time you’re in the water. We’re betting you won’t get very far!

Humpbacks, Spinners, Babies, Competitive Pods…a GREAT Weekend!

Aloha,
We had a great weekend of whale watching. On Friday’s Breakfast with the Whales, we found 3 whales who decided to spend quite a bit of time with us. At one point, one of them surfaced just 50 yards away from the boat! We also saw lots of breaches on the horizon (but we couldn’t get out to those whales). On our 10:00 Whale Watch, the wind began to come up…but we did see a Humpback and we also saw about 200 very active Spinner Dolphins. When we deployed the hydrophone on that trip, we did pick up some very faint singing.
On Saturday’s Breakfast with the Whales we saw 11 Humpbacks. The first 5 were off in the distance…but then we came upon a competitive pod of 6 whales south of the Bay. This pod circled us TWICE, coming within about 6 feet of the bow (we weren’t moving at that point). We saw a few head lunges, lots of motor-boating (a description that sounds like exactly what it is…whales moving thru the water with their heads above the surface, so they look like high-speed boats), and some tail lobs! The strong winds up north on Saturday prevented us from running the 10:00 Whale Watch, however our guests aboard our Whales and Cocktails cruise encountered the same competitive pod as the morning guests did (at least we think it was the same group of whales). We got to see a few peduncle throws from this pod and the same exciting chase scene.
On Sunday’s Breakfast with the Whales, guest saw 8 whales…lots of breaches and pec slapping in the distance, and a close enough encounter that some of us got covered by what comes out of the blowholes when the whale spouts (see the Humpback Fact of the Day for more on this). On our 10:00 Whale Watch from Kawaihae, we spent a considerable amount of time with a Cow/Calf pod just outside of the harbor…and we saw a few more whales in the distance. And we finished the weekend with our Whales and Cocktails cruise where we saw 7 whales…but the coolest thing that happened on that trip was watching a huge pod of Spinner Dolphins surround two of the whales. We’re not really sure how much inter-species communication actually goes on, but it sure appears to us that the dolphins are interested in playing with the whales (and that the whales find their little cousins to be pretty irritating)!

Captain Claire’s Humpback Fact of the Day: When you see a whale spout, you’re actually looking at an interesting combination of things. Some of what you’re looking at is condensation from the whales’ lungs (the same thing you’re looking at when you see your own breath after exhaling in a cold environment); some is atomized ocean water (Humpbacks live in a wet world, and there’s always some of the ocean pooled on top of their blow holes when they surface); and…since Humpbacks don’t have cilia in their respiratory tracks (little hairs)…a lot of what you see (and occasionally feel) is actually mucus! Yuck!

A Surprise Close Encounter

Aloha,
Wednesday’s Whale Watches started out with a bang! Guests aboard Seasmoke’s Breakfast with the Whales cruise were delighted to find a whale just a couple miles off shore of Anaeho’omalu Bay. We hung out with this whale for quite awhile, as s/he was surfacing pretty frequently. At one point, we were just idling quietly, watching and waiting for the whale to surface again. Everyone on the boat was scanning in different directions, and many of us had our theories about which direction the whale was next likely to pop up when we all got a HUGE surprise as the whale surfaced just 25 feet from the boat! Apparently this whale was as interested at getting a close look at us as we were at getting a look at him. On our 10:00 Whale Watch, we saw 8 different Humpbacks…including a competitive pod of 3. At one point, the lead whale of the pod (which is invariably a female) surfaced at the 9:00 position, and then swam under the boat and came up again at the 1:00 position so everyone on board, regardless of which side of the boat they were standing on, got a close encounter! We also saw Spinner Dolphins on this trip…most of them appeared to be resting, but we did see one end-on-end spin!

Captain Claire’s Humpback Whale Fact of the Day:Though the Humpbacks we typically see in Hawaii average between 40 and perhaps 50 feet long, there is anecdotal evidence that the largest Humpback killed by whalers was 88 feet long. This Humpback was taken in the Caribbean.
