Competition Heats Up

Aloha,

Guests joining us on Thursday’s Wake up With the Whales got to see the whole gamut of competitive activities. It was pretty windy out there, but Captain Baker found us a competitive pod of 4 adult humpbacks (no calf). While we were watching, two more males joined the fray. We saw at least a dozen breaches, and too many head lunges, pectoral slaps and tail lobs to count. We also saw a few peduncle throws from the competing males (either that, or the peduncle throws were from the female trying to express her excitement…or irritation….while all this was going on, it was difficult to keep track of who was being chased and who was doing the chasing). We were able to keep up with this group on a parallel path for more than 45 minutes before we finally had to turn and head back to the bay. With less than a week left for our Whale Watch Season, we’re really treasuring these moments. And we’re pretty sure that the Humpbacks still remaining around Hawaii are treasuring every encounter they’re having with each other too!
Mahalo and have a great weekend. I’ll send a recap of the weekend’s sightings on Monday.

Captain Claire’s Humpback Fact of the Day: The barnacles called “Coronula diadema” live only on Humpback Whales, and they seem to prefer to live on areas of the whale where the water flow is consistent (chin and fins). Though researchers aren’t completely sure how the barnacle can even find a whale to live on, there is some speculation that because the barnacles are spawning during the winter in Hawaii, the whales here are swimming in “barnacle larvae soup”. When a whale swims by, those “baby” barnacles chemically sense it, and hop on where ever they can. They use their antennae as “feet’ and walk around the whale till they find a suitable spot (which can take quite a while… if the barnacle were the size of a person, the whale would be 20 miles long). Once they find a spot they like, they flip over and produce tube-shaped cavities in their shells that actually draw in prongs of growing whale skin, holding their position on the whale for life.

Competition Heats Up

Aloha,

Saturday’s morning Whale Watches were full of competiton. On our 8:00 Wake up with the Whales  Cruise from Anaeho’omalu Bay we paralleled a competitive pod of 5 or 6 humpbacks including Mom and her baby for an hour and 20 minutes. We saw them as we left the bay, and were able to stay with them till we got to Puako. These whales were so active we never were really sure exactly how many were in the pod. We saw lots of head lunges, peduncle throws and tail lobs from all the adult whales. Unfortunately, we had to turn back before we could see the resolution of the competition. On our 10:00 Signature Whale Watch from Kawaihae, we also got to watch a competitive pod including Mom and her baby. In this case, we were able to see the pod dissolve, as one of the males gave up, leaving Mom and baby with just a single escort. Before they broke up, we saw lots of shoving and pushing between the two males, and got to see a some lunging and head lifts too. And on our Whales and Cocktails Cruise, we had a repeat of the action we saw on Thursday’s Whales and Cocktails Cruise…LOTS of breaching from Mom, an Escort and baby. Baby seemed to be reacting to the adults around him, because he didn’t start breaching till after they finished, but once he started, he just didn’t want to stop!
On Sunday, we operated back to back to back cruises on Alala from Kawaihae Harbor. All day long we were seeing competitive pods, and pods of Mom/Baby usually accompanied by multiple escorts, but occasionally accompanied by just one escort. Highlights included head lunges and peduncle throws from competing males, lots of breaching (from the calves too), and both tail lobs and pec slaps. Whenever we dropped our hydrophone, we heard lots of singing over a range of distances (some loud, clear voices, and a lot of faint voices joining the choir too).
Mahalo,
Claire
Captain Claire’s Humpback Fact of the Day: Recently, researchers studying singing male Humpbacks were able to determine that immature males do join mature humpbacks in singing. These researchers theorize that every voice is important as a means to attract females to the “arena” where the males have congregated. Since we know that the females don’t respond to an individual male’s song – it’s not like a songbird’s song, designed to attract a female and repel other males – the researchers theorize that the humpbacks’ songs are meant to attract females to the” arena.” And though the immature males don’t get to mate, they may benefit too by indirectly learning the songs and the social rules of mating.

Unusual Dolphin Joins Humpbacks

Aloha,

Our Friday the 13th started off really lucky for guests on the Wake Up with the Whales Cruise. Not only did we see 3 different cow/calf/escort pods, but we got to see a double breach within about 100 feet of the boat. On the 10:00 Cruise from Kawaihae, we watched a competitive pod dissolve before our eyes. We stayed with the losing male for awhile, watching him tail lob more than 40 times. Then we went in search of the Mom/Baby and winning escort. We found them right on the wind line, and as soon as the wind moved in, the baby went crazy – breaching more than 30 times.
On Saturday’s Wake up with the Whales Cruise, we found a couple different Mom/Baby/Escort pods. The first pod was swimming quietly and we didn’t want to disturb them, so we cruised past them to another pod where a baby was breaching repetitively. When we deployed the hydrophone on this cruise, we heard some very loud and clear sounds, so we know there was a lot going on below the surface too. On our Whales and Cocktails Cruise, Captain Mark found a large competitive pod of 8 or 9 whales (difficult to count) just south of Anaeho’omalu Bay. Before we got to them, we saw a lot of breaching going on, and while we watched, the pod split into two pods — half of whom stayed right around our boat, lunging and blowing bubbles for more than 30 minutes.
On Sunday’s Wake up with the Whales Cruise, we saw 5 different Cow/Calf pods, lots of peduncle throws and lots of pec slaps. The highlight of the cruise though was watching an adult humpback breach fully out of the water about 150 feet behind our idling boat. On the 10:00 Whale Watch from Kawaihae, Captain Ryan reports an unusual sighting of a dolphin accompanying Mom Humpback and her calf just outside the break wall at the harbor. This lone dolphin was acting just like a whale, diving and surfacing in conjunction with the Humpbacks. The dolphin looked a lot like a Spinner, but his dorsal fin was a bit more hooked — maybe a juvenile Bottlenose? Guests got to watch this unusual trio for the entire duration of the trip…at one point, actually seeing all three sound together. Mom didn’t seem bothered by the dolphin’s presence, allowing her calf to interact with him…and even when another small competitive pod showed up and seemed to veer the dolphin away from Mom and her baby, the dolphin returned as soon as they left. As soon as I get a photo from Captain Ryan f this unusual dolphin, I’ll post it.
Hope your weekend was as great as ours!
Claire
 
Captain Claire’s Humpback Fact of the Day: When we say we heard LOUD singing, just how loud do we mean? Well, Humpback whales have been recorded producing sounds at around 185 decibels. Because the decibel scales use different references for sounds underwater than through the air, that’s the equivalent of about 123 decibels for us on the surface…which is as loud as the amplified music at a rock concert when you’re standing directly in front of a tower of speakers.

Baby Whales Steal the Show

Aloha,

The weather cleared on Thursday, so we ran all of our cruises. As usual with a busy day, there’s just too much to report for one email, so here’s what we saw on just one of those cruises. On our 10:00 Whale Watch on Alala from Kawaihae, we started the day with a pod of Spinner Dolphins. As soon as those little guys heard the boat, they came right over to play in our bow wake. We got to see some very lively little dolphin calves spinning and jumping…but not to be outdone, the adults in the pod did some incredible twists and twirls too. After we passed the dolphins, we found a competitive pod charging around on the surface. We paralleled this pod for several minutes and they led us to two separate pods of Mom and her baby. Each of these babies was very active. For awhile, we were watching one calf breach repetitively off the port side of the boat, while the other was breaching off the starboard side. We also saw lots of flukes and spouts from other adult Humpbacks in the area.
Have a great weekend — I’ll send out a recap of our weekend sightings on Monday.
Mahalo,
Claire
Captain Claire’s Humpback Fact of the Day: How do Humpbacks keep their cool when swimming through our warm Hawaiian waters?  During prolonged exercise in warm water, excess heat is shed by increasing circulation to a network of capillaries (in Latin they’re called “retia mirabiliia” which translates to “miracle network”) near the surface of the Humpbacks’ flippers, flukes and dorsal fin — the excess heat is shed to the external environment. In fact, many researchers believe that whales lifting their pectoral fins into the air, or resting with their flukes exposed vertically are actually trying to cool off.

Baby, Baby, Baby!

Aloha,

Tuesday’s Whale Watch Cruises were a lot of fun. On the Wake up With the Whales Cruise on Seasmoke, the theme of the morning was “Babies”. We saw so many different Mom/Baby pods that when we asked the guests if they had kept count, all anyone could come up with was “a bunch”…and then we saw two more. So I guess we saw “a bunch plus two”. We had several close encounters with calves surfacing near us followed by their Mom’s and the occasional escort. We also were very lucky when a calf decided to take a close look at all of us on our idling boat and swam right up to us. Mom was pretty permissive, but after about 2 minutes, she must have decided enough was enough, and we got to watch her surface under her calf, pick him up in her rostrum, and roll him away from us. All this took place in just 40 feet of water! We also heard some loud songs through our hydrophone, and got to see a breach, some tail lobs, and some pectoral slaps (including double pec slaps). On our Whales and Cocktails Cruise, we spent a good deal of time paralleling a very active competitive pod. We got to see lots of lunges, and lots of shoving around, and also heard quite a bit of trumpeting from these “out of breath” whales as they charged around on the surface.

Captain Claire’s Humpback Fact of the Day: One of the best ways whale watchers have to identify individual Humpbacks is by the unique markings on the ventral (underside) of their flukes (tails). Currently, the National Marine Mammal Laboratory based in Seattle maintains a data base containing more than 30,000 photos of the North Pacific Humpbacks flukes dating back to 1966, but other researchers, including those involved in the 3 season SPLASH (Structure of Populations, Levels of Abundance and Status of Humpbacks) project have also used these patterns to identify who’s who in the whale world and estimate population levels.

Very Different Activities Observed Throughout the Day

Aloha,

Wednesday was our last  9 Whale Watch Charter day this week. What was most interesting is the differences between what we saw on the cruises…especially because we departed from the same locations and had very little time in between cruises. Guests joining us on our first Seasmoke Cruise got to see lots of spouts and flukes from pods of two adult Humpbacks. We also saw a few pectoral slaps, and a few peduncle throws happening from a pod of three whales. As we gazed out to the horizon, we also saw some huge splashes from breaching whales. Just one hour after we returned from that cruise, we departed again, and this time we saw  so many close-up breaches that we actually lost count. We were watching a competitive pod of 5 adult humpbacks for the first hour of the cruise, and these whales came right up to our boat, swimming across our bow, diving and surfacing on all sides of the boat. We also saw a bunch of head lunges and tail lobs, and a couple of double pec slaps. After about an hour of non-stop activity, this pod took a deep dive, and either separated, or swam off fast and far, because we never saw them again (though we did see spouts, flukes, and plenty of other whales). After that incredibly exciting cruise, we went out again two hours later. This time, it took us awhile to even see a spout. But the whales found us, and we ended up watching 6 different pods of two adults, and towards the end of the cruise, got to see a Mom/Baby/Escort pod. To us, it appeared that baby was leading the adults around…since baby kept changing directions, followed by mom and the escort. They came pretty close to our boat, checking us out too. We actually got to watch baby lying on mom’s rostrum, and as mom swam, we got to watch the baby roll right up her head and onto her blowholes!
Captain Claire’s Humpback Fact of the Day: Researchers have observed that Humpback calves are very playful, investigating all kinds of objects in their environment (including our boat), interacting with their moms, and even interacting with passing pods of dolphins. But for as many calves as we see in Hawaii during the winter, we never have observed the calves playing with each other. Though we’re not sure why this is, perhaps the new moms won’t allow a calf not her own to approach, because she doesn’t want to feed the wrong one.

Mugged by Two Adults

Aloha,

Tuesday was another 9 Whale Watch Cruise day for us. Highlights included watching a competitive pod of 5 whales from the Alala from 8:15 till 9:45. We found this pod off of Spencer Beach, and paralleled them as they swam north. We saw lots of head lunges, and lots of jaw claps. We also saw 6 pectoral slaps from the whale in the front of the pack, and lots of head butting from the whales behind. At one point, we saw the lead whale peduncle throw on top of one of the followers. And when we stopped the boat and deployed the hydrophone, the sounds we heard were so loud they almost shook the boat. On the next cruise, the competitive pod was no where to be found, but we did see lots of pods of two…and one pod of two came to see us for more than 20 minutes, surfacing right next to us, and diving right underneath us. Guests aboard Seasmoke and Manu Iwa departing from Anaeho’omalu Bay also got some great sightings with a couple of close encounters. Each cruise reports seeing 15 – 20 different whales, most in pods of two, but there were several competitive pods of 5 and 6 whales too.
Mahalo,
Claire
Captain Claire’s Humpback Fact of the Day: Humpbacks produce sounds in frequencies ranging from 10 hz to 24 khz. A healthy young adult human can generally hear sounds in frequencies between the ranges of 20 hz to 20 khz.

Competitive Pod Captivates

Aloha,

For the next three days, there’s a big convention on the island (SAP), so we’re running 9 different Whale Watch Cruises every day. And since it’s still height of the season for the Humpbacks in Hawaii, we’re seeing too much to report in one email…so I’ll just list some highlights from a couple of our trips. On the Alala, guests got to see a Mom/Baby/Escort pod up close. The seas were calm, so we were just idling, and baby kept approaching closer and closer every time he surfaced. Generally, we’ll watch Mom get fed up with that activity and eventually push her baby away, but not today. All three of theses whales came right up along side of the boat and stayed there for quite awhile. We also got to see baby breach several times! On our last cruise of the day on Seasmoke, we saw our first Mom and Baby pod about midway through the cruise, but we spent most of our time watching a competitive pod of 5 whales in a very aggressive chase. These whales didn’t care that we were there as they kept changing directions all around us. We watched one of the big males head lunge with an open mouth right on top of another whale at least a dozen times. We also got to watch lots of shoving at the surface — we could see one of those big guys push his big head right into the side of another whale and shove him aside. The whale in front of the chase (we’re almost positive it was a “she”) expressed her displeasure or excitement or irritation with a couple of pec slaps and peduncle throws…but mostly she just kept changing directions. We finally had to leave the pod to head back to the bay…and on the way back we had a couple more close encounters with a lone humpback, and then with a very small calf and his mom. Baby had a very angled dorsal fin and was pretty light in color so we’re guessing he was pretty young.
Mahalo,
Claire
Captain Claire’s Humpback Fact of the Day: A baby whale, called a “calf” looks so small and cute when seen playing with her Mom. But everything is relative…when the calf is born, she can already be 10 to as much as 15 feet long, and she weighs 2000 to 3000 pounds! The calf is about 26 feet long when it’s weaned (at 10-11 months).

Spouting at the Ladder

Aloha,

As usual, a whole weekend’s worth of whale watching provided us with way too much to

Breach

Breach (Mahalo to Helen Turner for this image)

talk about in one email, so I’ll just recap a few of our favorite cruises.

Our weekend started out fantastically with guests seeing the whole gamut of surface activities on Friday’s Wake up with the Whales. Not only did we see 5 different Mom/Baby/Escort pods, but we got to see lots of full breaches, pec slaps, tail lobs, and head lunges too! On Friday’s Whales and Cocktails Cruise, all the action was right in front of the Hilton Waikoloa Village where we found a Mom and her calf. We got to watch a competitive pod form as two males approached Mom and baby. Once these guys got to where Mom and Baby were resting, they got really active — we couldn’t believe our eyes as we watched them smack each other with their pectoral fins and peduncles, and shove each other around with their huge rostrums. On Sunday’s Wake up with the Whales on Alala, we found a Mom, Baby and Escort right outside of the harbor. We enjoyed watching them surface multiple times, but since we didn’t want to bother them, we decided to leave and check out some action a bit further down the coast. This turned out to be another Mom/Baby/Escort pod. This time we got to see baby breach, followed by Mom, followed by the Escort. And right after that, both adults breached again! And finally, on Sunday’s Whales and Cocktails Cruise we had two close encounters in the beginning of the cruise by two different whales. After that excitement, we headed out to sea a bit and idled. Two humpbacks spent over an hour RIGHT under the boat, spouting between the trampolines and all around us. We saw a breach and a tail lob 30 yards from us. The whales wouldn’t leave, and finally, Captain Ryan had to roll out the staysail so we could get back. As we started to sail away, one of the whales chased us down and followed us back to the bay.
Mahalo,
Claire

Captain Claire’s Humpback Fact of the Day: You may have read about the entangled Humpback whale that was just freed by the Whale Entanglement Response Team off the Maui coastline (if you haven’t, click here )…but did you notice the route taken by the whale since it was first spotted off the Hamakua coast? In the space of a week, this whale circled the Big Island, and then crossed the Alenuihaha Channel to Maui — all while entangled in more than 200 feet of heavy line and crab buoys. Pretty amazing — and we know it’s common for Humpbacks who aren’t all tangled up to swim between the islands too — not in any particular direction we’re aware of. Some travel south to north, and others north to south…much like our human visitors!

Magic on the Water

Aloha,

Our Wednesday Whale Watches were really fun. On our Wake up with the Whales Cruise on Manu Iwa, we got to see 4 double breaches — we’re never really sure how whales can time that so perfectly and it’s astounding to see. Our idling boat was also approached by a couple of big adults who decided to take a good look at our hulls, diving just below us. The water was so calm and flat that we could almost count the tubercles on their pectoral fins as they swam underneath. And our 10:00 Whale Watch on Alala was just magical. Shortly after we left the harbor, we found a Mom with her baby and an escort. According to our on-board naturalist Donna, guests could clearly see baby resting on Mom’s rostrum (her head). They stayed that way for a very long time, until baby rolled away. Then, Donna reported seeing some splashing further down the coast so Captain Kino cruised over to see what was going on. There were 3 adult humpbacks on the surface just rolling around. It wasn’t aggressive…they were showing their flukes, their bellies, and their pec fins. They kept rolling around each other getting closer and closer to our idling boat. Then they decided to dive underneath us, but even then they stayed close enough to  the surface for us to see them. After passing underneath us, we had to head back to the harbor where we saw our  Mom,baby and escort again…this time accompanied by a pod of Spinner Dolphins! And on our Whales and Cocktails Cruise, Captain Kealohi reports that guests saw about two dozen different whales…lots of Mom/Baby pods (most accompanied by escorts), and 4 different competitive pods.
Mahalo,
Claire
Captain Claire’s Humpback Fact of the Day: Researchers have observed that female Humpbacks don’t associate with each other at all while they’re in Hawaii. This is especially interesting in light of the fact that the females do associate with each other in Alaska — they’ll even feed cooperatively there. Since the females come here just to mate (and calve), we can postulate that female-female interaction must somehow get in the way of successful mating. Maybe groups of females would attract too many competitive males for safe mating to occur….what do you think?
