Humpbacks Can Sleep – But How?

Posted on by
Aloha,
Between our regularly scheduled cruises, our kid’s field trip cruises, and some private cruises, we ran 5 different Whale Watch Tours yesterday — with all those cruises, there are just too many details to send in an email. Suffice it to say, the majority of the pods we saw throughout the day were Mom/Baby/Escort pods. We did get to watch some pretty wild surface action on a couple of our trips, with competitive pods charging around the Mom/Baby duo. We saw tail lobs, peduncle throws, a couple of breaches and lots of spouts and dorsal fins too. We deployed our hydrophones several times throughout the day with mixed results. We were always able to hear the underwater chorus the whales listen to all day, but only a few times did we hear very loud singing (indicating close-by males). Based on what we were watching on the surface, the males close by to us were way too busy to stop and sing!
Have a great weekend,
Claire
Captain Claire’s Humpback Fact of the Day:Humpback Whales don’t sleep as soundly as we do — if they did, researchers believe that they’d drown. Humans breathe in response to carbon dioxide build-up in our blood, but Humpbacks and other marine mammals have to keep part of their brain awake at all times so they remember to breathe. When a Humpback sleeps, he floats just under the surface of the ocean, and comes up to breathe every couple of minutes. We call this behavior “logging’ as the whale looks a lot like a floating log.

Muggings, Close Encounters, and Lots of Surface Action

Posted on by
Aloha,
Thursday was an incredible day for whale watching. Between our 3 boats, we ran a total of 11 Whale Watch Cruises, so reporting details for each would be pretty difficult. Highlights included several muggings (the first on our Breakfast with the Whales Cruise, where we were approached by two different Mom/Baby pods at different times). On our 10:00 Cruise from Kawaihae, we also were approached several times by different whales checking us out. We got to see a whale calf attempting multiple breaches (sometimes he just couldn’t quite get the timing right and did more of a back-flop). We also watched a competitive pod of 6 whales charging along the surface of the ocean. Our afternoon trips allowed our guests to see pretty much every surface behavior of the Humpbacks in Hawaii including tail lobs, pec slaps, head lunges, peduncle throws, throat inflations (from whales in competitive pods), and multiple breaches.
Mahalo… have a wonderful weekend, and Happy Valentines Day!

Captain Claire’s Valentines Day Humpback Fact of the Day:  A Humpback Whale has a big heart. An 80,000 pound whale’s heart averages just over 400 pounds, and according to measurements made by the Nelson Institute of Marine Research, beats an average of somewhere between 10 and 30 times per minute.

Cloud Cover Doesn’t Alter Activity Levels

Posted on by
Aloha,
Thursday morning we woke up to overcast skies, and on our 10:00 Whale Watch, one of the first questions a guest asked me was “What do the whales prefer? Sunshine or clouds?”. I’ve never read any research documenting surface activity levels based on cloud cover, but based on what we got to see on this cruise, I’d have to say the whales sure didn’t let the grey skies slow them down. We spent much of our time watching a competitive pod of 4 whales. The one in the lead (which we’re guessing was female) spent a lot of time at the surface pec slapping and tail lobbing. We got to see some great bubble trails from the primary escort (researchers suggest the primary escort blows bubbles as a way to mask the presence of the female from the males behind him), and a couple of times he lifted his head showing us an inflated throat (another aggressive move — inflation makes him look bigger to the other males). We also saw not one, not two, but 3 breaches from this pod…and all them were right in front of us. During the cruise, we also saw lots of other Humpbacks spouting, peduncle throwing (twice) and tail lobbing.
We went back out again at 12:30 with 50 keiki from Wai’aha School (and their parents and teachers). Though we were only on the dock for about 5 minutes between the trips, the weather changed entirely. The wind came up – and so did the whales! We saw lots of tail lobs and peduncle throws during this cruise. All told we saw more than two dozen whales. And when we deployed our hydrophone, we heard very loud clear songs.
On our Whales and Cocktails Cruise, not only were we visited by a Mom/Baby/Escort pod, but we got to watch a tail lob competition between two adult whales.
Mahalo, and have a great weekend,
Claire
Captain Claire’s Humpback Fact of the Day: The smooth round flat spot we see on the water after a whale dives is called the “footprint”. Whalers thought it was caused by oil from the whale’s skin calming the surface of the water, but water samples have proven that theory to be false. When a whale dives (or kicks just below the surface) his flukes break the surface tension of the water and create a vertical wake, forming the circular footprint.

Quiet Humpbacks on Monday

Posted on by
Aloha,
Our Monday morning Humpbacks were a quiet bunch of whales. On our Breakfast with the Whales Cruise, we saw a LOT of whales – all in pods of two, and interesting, all of them were adults (no calves). All these whales were pretty calm, so we saw a lot of spouts, a lot of dorsal fins, and a lot of flukes. At the end of the cruise, one whale did perform a peduncle throw (which researchers believe is a significant act of communication – see below).On the 10:00 Whale Watch, we saw very similar activity — lots of pods of two who were just spouting at the surface before diving again. We did get to see one very identifiable whale who we watched for awhile. This whale had a chunk gone from his fluke (so he was easy to keep track of). Towards the end of the cruise, this particular Humpback must have gotten curious about all the shouts of encouragement coming from our boat as he surfaced close-by to check us out.
Mahalo,

Captain Claire’s Humpback Fact of the Day: Why would a whale waste the energy to throw the back half of his or her body out of the water in a Peduncle Throw (sometimes repetitively)?? Since the whales aren’t telling, all we can do is try to interpret their behavior in terms of what else is going on in their lives at that moment. We know that Humpbacks very rarely eat while they’re in Hawaii, and since a Peduncle Throw is a huge expenditure of energy (if you don’t believe me, try it yourself next time you’re in the ocean), it’s got to be important to the whale. Throwing half of yourself out of the water results in a huge splash and might be a way to communicate location, health, excitement, aggression or irritation to near-by whales. Especially if the near-by whale happens to be so near that he gets landed upon!

Lots of Competition

Posted on by
Aloha,
With the challenging weather conditions on Tuesday, we were only able to run one Whale Watch Cruise – but it was a good one! Guests on Tuesday’s Breakfast with the Whales were fortunate enough to watch a competitive pod of 6 whales. As usual, with a competitive pod, there was a lot of surface activity going on – pectoral slaps, peduncle throws, and even a couple of tail lobs. We also saw a couple of breaches, but they were from whales that were further away.
Mahalo,

Captain Claire’s Humpback Whale Fact of the Day:The Humpbacks we see off Hawaii’s coastlines travel quite a bit between the islands, but researchers have yet to observe a directional trend. In other words, some whales travel North to South, some South to North, and some travel back and forth…a lot like our human visitors.

Suprised by Spouts

Posted on by
Aloha,
Guests on both of our Whale Watch Cruises on Thursday got to experience the best that Whale Watching in Hawaii has to offer! On the Breakfast with the Whales Cruise we found Humpbacks just outside of the bay – we watched them for awhile, but were distracted by all the splashing going on about a 1/2 mile further. So went to check it out and found some whales that wanted to look at us. They came right by the boat more than once. We also saw pretty much every surface display you ever read about in the whale watching books – pec slaps, peduncle throws, head lunges and breaches! Guests on our 10:00 Whale Watch also had some great viewing. We watched a pod of three Humpbacks (most likely one female and two males – based on their behavior). The two we were assuming to be males got into a competition – shoving each other around – until one of them must have had enough and swam away, leaving the other two to swim off together out to sea. As we were all enjoying that sight, two whales that we didn’t even know were there surfaced right next to us, startling all of us with their loud spouts (if you’ve ever heard the powerful sound of a whale spout close by, you’ll know exactly what I’m talking about) And if that wasn’t enough…for our grand finale, as we were coming back into the bay, we all got to see a big Humpback breach completely out of the water!
Mahalo and have a great weekend!

Captain Claire’s Humpback Fact of the Day:  When we watch a surface active competitive pod of whales, we assume it is comprised of one female either leading or being chased by a group of males. It often appears that every male is competing with every other male for access to the female. Recently researchers have observed that male humpbacks may form coalitions, working together to corral the female so that one may have easier access to her. 

Juveniles Cruising the Coast

Posted on by
Aloha,
Guests on all of our Thursday cruises saw Humpbacks. On the 10:00 Whale Watch on Alala out of Kawaihae, we cruised around for almost the whole trip till we found a juvenile Humpback right in front of the harbor. This whale was pretty mellow, just surfacing, spouting, and then diving for 7 minutes before coming up and doing it all again.  Since it took so long for us to find each other, and with the support of the guests on board, Captain Will decided to stay out for an extra half hour so we could all enjoy the experience.
On the Whales and Cocktails Cruise, two sub-adult whales found us and appeared to be curious about our presence, They hung around with us for about 30 minutes! At one point, one of them surfaced about 20 feet from our stern, so we all got a good look at each other. We also got to see a peduncle throw from one of them (a “peduncle throw” describes the whale throwing the back half of his body out of water – generally thought to be an expression of aggression towards another whale close by).
Hope your Thursday was as interesting and fun as ours!
Mahalo,

Captain Claire’s Humpback Whale Fact of the Day: It takes an average of just under 3 months for the Humpbacks to migrate from the summer feeding grounds in Alaska to Hawaii (although at least one Humpback was seen in Alaska and then in Hawaii just 45 days later). That means the Humpbacks are generally swimming at a speed of about 4 knots (a little bit faster than we travel when taking a brisk walk)!

Young Calves and Lots of Escorts

Posted on by

Aloha,

We started our weekend with some strange stormy weather on Friday. On our Breakfast with the Whales Cruise, we spent most of our time with a Mom/Baby/Escort pod. Baby led Mom right up to the boat a few times, and though the baby seemed pretty big and had a fairly straight dorsal fin (indicating he was not a new-born) both Mom and the Escort were fairly small (by Humpback standards), suggesting to us that they were both fairly young. We did see some head lunging about 800 yards from us too. On the 10:00 Whale Watch, we saw 15 different Humpbacks, and 4 different Mom/Baby pods.
On Saturday’s Breakfast With the Whales we saw every behavior we could hope for on a whale watch including multiple breaches from a very energetic calf, adult tail lobs and peduncle throws, pec slaps, and even some adult breaches!
And on Sunday’s Breakfast with the Whales, we found 3 different Mom/Baby/Escort pods, including one with a very, very small calf. Each of these pods decided to swing by the boat, so we had some great close encounters. We also saw a double breach from two adult whales (always exciting) and towards the end of the cruise we found a competitive pod who were doing a lot of trumpeting, head lunges and bubble blowing beneath the surface. At one point we were downwind from a spout and it really smelled kind of horrible. We finished the weekend of Whale Watching with a Whales and Cocktail Cruise from Anaeho’omalu Bay. We got to see several Mom/Calf pods, and they got to see us too (we had lots of close encounters). We also saw a lot of tail lobbing, breaching, and peduncle throws. And when we dropped our hydrophone into the water, we were surprised by the clarity of the songs we heard. Oh…and at the end of the day, the sun came out again, making for a beautiful end to the weekend.
Mahalo,

Captain Claire’s Humpback Whale Fact of the Day:  According to research conducted in Japan, the peak estrus period for Humpbacks (i.e. when females are in heat) overall, is between the end of January and the end of February, but the peak estrus period for females with a calf appears to be several weeks later. Our frequent observations of pods of Mom and Baby who are accompanied by an escort this time of year seem to support the validity of these findings.

Spy Hops and Songs

Posted on by
Aloha,
On Thursday’s Breakfast with the Whales, guests saw lots of whales surfacing, breathing and diving. It seemed like no matter which direction we looked, a whale was up. We also saw 4 breaches close to the boat and had a couple of nice close encounters with curious Humpbacks. Our Whales and Cocktails Cruise started off kind of slow, with lots of “blows and goes”, but then we found a Mom and her baby who wanted to play with the boat. They came right up to us and both of them spy hopped twice, clearly taking a look at us. We then found a couple of other whales who seemed very interested in us whenever we had the boat in gear and were travelling parallel to them. As soon as we turned the engines off and went into stealth mode, these whales would dive…so we’d start up again, which would bring them to the surface. It might have been a coincidence…but it sure seemed like they wanted to travel along side a moving boat, and quickly got bored with a quiet one! We ended the evening seeing a couple of breaches a little further away, and some HUGE peduncle throws close by.
Mahalo, and have a great weekend. I’ll send the next report out on Monday.

Captain Claire’s Humpback Whale Fact of the Day:  Researchers studying the totally geographically isolated Arabian Sea Humpbacks have recently noted that these Humpbacks sing songs that are a whole level less complex than the songs Humpbacks in every other ocean of the world sing. Arabian Humpback songs are comprised of notes, making phrases, that are repeated in the same order, while other Humpbacks group the phrases into themes and the repeated themes comprise the song.
If I’m interpreting this correctly, the Arabian Humpbacks’ version of say “Old McDonald Had a Farm” would feature only one farm animal, and  they’d be singing about that one animal over and over and over. Humpbacks elsewhere would be able to use the structured verse to sing about lots of different animals on the farm…If there are any music theorists out there please help me out. Here’s a link to a story about the research….http://www.bbc.co.uk/nature/21592348.

Curious Calves All Weekend Long

Posted on by
Aloha,
We had nice weekend of whale watching – too many trips to report everything, so I’ll just summarize the highlights, starting with Friday’s Breakfast with the Whales cruise where 3 adult humpbacks decided to surround our boat for close to 15 minutes. On Saturday’s 12:30 Whale Watch from Kawaihae, we got to watch an interesting interaction between Mom and her baby. The calf breached about 10 times before mom did a big peduncle throw landing her tail just about on top of the calf…was Mom trying to tell her baby “enough! settle down!”?. We also saw some beautiful fluke dives from a different Cow/Calf/Escort pod – Mom’s flukes were all black, and the escort had some very distinct white patches on his flukes. On Saturday’s Whales and Cocktails Cruise we saw 5 different Cow/Calf/Escort pods. We had two really, really close encounters when different escorts came right up along side the boat. We also saw some pretty vigorous tail lobbing and peduncle throws from a different pod. On Sunday, guests aboard our Breakfast with the Whales Cruise saw lots of breaches in the wind, but were most excited by the Mom and calf who circled our boat for more than 20 minutes. We all got a very good look at these whales (and they got a very good look at us too)!. And a similar thing happened to us on the Sunday Whales and Cocktails Cruise when a Mom and her calf decided to spend a considerable amount of time right next to us. We also saw a series of tail lobs and a peduncle throw from a competitive pod, and lots of breaches but they were in the wind, and we decided it wasn’t worth it to travel out there to see those whales.
Mahalo,

Captain Claire’s Humpback Whale Fact of the Day: At birth, a Humpback Whale Calf weighs betweeen 3% and 4% of his Mom’s weight. Interestingly, at birth, human babies average 4%-5% of their Mom’s weight.
