Azores: It’s September already

On the last day of August, the lookout said he had seen four sei whales to the south of the islands. What he forgot to mention was that the wind was whistling through the channel between Pico and Faial, making it extremely difficult to spot the whales. We waited in the area for almost an hour, moving slowly towards the west, when finally, I spotted a blow! A single sei whale seen in between the waves. It seemed to be avoiding the boats, so we did not stay too long. The camera stayed safely tucked inside its case. I am not sure if I would have obtained an ID photo anyway with all the waves and unpredictable movements of the whale, but there was a very good chance the camera would get wet!

Summer was back on 1 September. We went a long way down the south coast of Pico, where I was expecting to see the “Whitehead” group yet again. But when the first whale showed the fluke, I was surprised, it was not the “Whitehead” group after all. Finally some different individuals. There were two seen, one with a fairly small calf. When matching the flukes later in the day, I got a second surprise, “1368” has been seen in 1990, 2015 and now 2020. The other individual had been seen in 2015 as well.

After the sperm whales we were directed to a group of pilot whales. I do not think I have seen such calm pilot whales in a very long time. At one point there was one individual about 3 m from the boat. Although at the end, they “woke up” and all dived quite quickly. We also had a couple of groups of common dolphin on the way home. One of the common dolphin had quite a distinctive fin, probably from an encounter with monofilament fishing line. The light was amazing and I even managed to get a couple of nice photos of the main seabirds that we see in the Azores. The Cory’s shearwater and common tern.

On 2 September, we were again working towards the north of the islands. The lookout had seen sperm whales as well as baleen whales. We were lucky to find the sperm whales, because they had just started to socialise at the surface, which means they are not clicking, so we would not be able to use a hydrophone to find them. There was a very very small calf with three adults. It appeared to be a “meet the calf” encounter. The calf had a floppy dorsal and flukes that were still curled as well as distinct foetal folds. Luckily, the whales showed some of their flukes while socialising, so we did get the ID images. They also showed their heads out of the water with their mouths open, giving us a chance to see their teeth. Then it was further out to sea to where a couple of sei whales were feeding with spotted dolphin. One of the sei whales made a few lunges to scoop up schools of baitfish, unfortunately a bit far to get good images.

The north of the islands has been full of whales the last few weeks and we were back to the north again on 3 September. First stop was a sei whale that may have been feeding at depth, it was making dives of 2-3 minutes. The sperm whales were a bit further out today and they were next, with a group of spotted dolphin seen along the way. At one point there seemed to be sperm whales in every direction. I got five flukes in the morning and then in the afternoon, we saw three different groups of sperm whales. First it was the same as the morning, with a sei whale surfacing about 200 m from where one of the sperm whales dived! This sei whale was the same as the lunging whale from yesterday. It was time to see some dolphin and a group of spotted dolphin were feeding, with a few making some spectacular leaps (when the camera wasn’t pointing their way). As we headed for home, we thought we might detour towards where the sei whale had been seen, but instead we found a group of six sperm whales that became seven just as we were leaving. Only one of these whales showed its fluke, it appeared that a social group was forming. But the sperm whales weren’t done with us, because I spotted yet another blow as we were on the way back to harbour and this time it was one of the “Northern Ladies” one of our well-known groups from the north of Faial. Matching photos in the evening, I had another surprise, more long-term matches. Two of the whales from the morning were first seen in 1995! We also saw a large group of striped dolphin, which were their usual shy selves.

On 4 September, the weather began to turn and we headed to the shelter behind Pico, rather than have a very bouncy wet trip in the north. The lookout had seen a sei whale early on, but then rain obscured his view. We headed out to a group of bottlenose dolphin, hoping that the whale would re-appear. And we were lucky, after a spread-out group of feeding bottlenose dolphin and another group of spotted dolphin, we observed a single sei whale moving in large circles making dives of a few minutes, most likely feeding at depth. On the way home, we encountered a group of common dolphins that had a small mating group within it. There was also an individual with anomalous markings. There was also a group of 200 spotted dolphin, one of which had a chopped dorsal fin, probably like the common dolphin above from an encounter with monofilament fishing line. As a bonus we also spotted the same group of bottlenose dolphin as the morning, which although still spread out were exhibiting some signs of socialising, with spectacular leaps.

Another interesting bit of news came up. I was contacted by the researchers that spotted a mother and calf humpback in the Mediterranean to see if I recognised the fluke photo. I didn’t, but put them in contact with other people around the Atlantic and a match was found, with the Happy Whale program. The adult had been seen previously in Dominican Republic in 1986 and was spotted off Genoa in late August! It is very unusual to see humpback whales in the Mediterranean. Hopefully she will find her way back out, otherwise they will be on their own, without any con-specifics in the future. This is the link to the photo of the match, but if you want to see the rest of the info, you will have to scroll down on their page:

And while we are talking about links, there is now a page on ResearchGate, a networking site for scientists and researchers to share knowledge and contacts, that lists all the expedition reports and other publications that have come out of our expeditions in the last 16 (!) years. The Azores is the longest-running Biosphere Expeditions project and I could not have done all this work over the years, or been on the water as much in this coronavirus year, without the help of the hundreds of citizen scientists who have joined me over the years. Thank you very much! I hope to be welcoming you to the Azores again in 2021.

The weather has now turned windy for the next few days, which can happen sometimes in September, hopefully we will get a couple of days out on sea next week, before the next unsettled weather arrives. Signs that winter is coming.

Azores: Still “Whitehead” group and sei whales, plus dolphins

The windy weather eventually passed and I have been back on the water the last few days.

On  26 August, despite it still being a bit windy, we braved the elements. The “Northern Ladies” turned up for the first time this year, in their usual location to the north of Faial. There is a calf with a white head in the group, so we now have a “Whitehead Junior”, not to be confused with “Whitehead” from a completely different group! We also had a mixed group of striped and common dolphin, but it was a bit windy for the camera to come out.

On 27 August the seas had calmed down quite a bit, so it was easier to observe the animals. In the morning, we had at least some of the same animals as yesterday to the north of Faial, including a fairly new baby that we hadn’t seen yesterday (but we didn’t see the mother either). In the afternoon, we went to the south of Pico, since the whales in the north had disappeared offshore too far for the vigia to see. “2578” of the Whitehead group was seen as well as a single milling sei whale and then a mother and calf sei whale. The calf was very interested in the boat, circling us several times, appearing unexpectedly behind us a couple of times. We also saw spotted dolphin in the morning and again in the afternoon, plus a large group of bottlenose dolphin with calves in the afternoon. We also came across the biggest sunfish that I have ever seen. The fin, looked like an orca dorsal cutting through the water!

On 28 August, we were once again to the north of the islands. A very nice surprise, when I looked at the photos. “1333” first seen in 1990 as well as “2906” and “2907” first seen in 2005. Unfortunately, the wind picked up and I was unable to get more photos of the group in the afternoon.

On 29 August, we started the morning out with a sei whale before heading on to the sperm whales. Surprise, surprise, the Whitehead group are still hanging around on the south of Pico! Westerly winds prevented us getting back out in the afternoon.

And finally on 30 August, we were back to the south of Pico, where, I think, the Whitehead group was waiting for us! There was also a sei whale feeding on fish alongside spotted dolphin. We ended the morning with a mixed group of striped and common dolphin. The striped dolphin doing what they do best, run away from the boat! In the afternoon, the vigia could not see the whales, which had headed towards Pico when we left them. We will have to try again.

The final news on the harp seal is that it was an old male, judging by the teeth, and had not been feeding for some time. The only thing in its stomach were stones. Stones are not unusual to find in the stomach of seals, because they can not chew their prey, the stones help to break down the fish they are eating.


Azores: Plenty of sightings

On 22 August the day was split, with the morning spent to the north of Faial and the afternoon to the south of Pico. We started out with a group of bottlenose dolphin that included some small calves, followed by a few groups of feeding spotted dolphin. The sperm whales were next and after initial matching, have not previously been seen. The vigia also spotted a sei whale, so we detoured further offshore to see it. On arrival, looking at the dorsal fin photos, it was one of the sei whales seen the day before in the channel between Pico and São Jorge. It appeared to be feeding again. We saw the right side of the animal and it had a healing wound just below and behind the dorsal fin. At this moment, I do not know what caused the injury. Most likely is either a shark or orca attack, but it could have been something else.

In the afternoon, we started out with sperm whales. After the first fluke, I identified “2578” of the “Whitehead” group. I don’t know how long they are going to stay, but they have been here for two months now, which is remarkable. The lookout also spotted a group of pilot whales further offshore. On the way to the pilot whales, we came across a small group of bottlenose heading rapidly the other direction, so after a few minutes, we continued on to the pilot whales. There were no calves in the group of pilot whales that we saw, which is a bit unusual. So it is likely that the calves were in a part of the group that we did not see. On our way back towards Horta, we came across the same six bottlenose dolphin, this time heading back the other way! They did stop for a quick minute to ride our bow, but then continued on their way. Just before we got to Horta, a much larger group of bottlenose dolphin was seen to the south of Faial, probably the same group that we had seen in the morning.

On 23 August, we were looking to find a bit of calm water, since the wind had arrived a bit earlier than predicted. Unfortunately, the sperm whales had other ideas. They were spotted to the north of Faial and although the lookout said the conditions were ok, they were not great. We were delayed by a group of bottlenose dolphin just as we arrived to the north of Faial, that were heading towards Pico, so we didn’t remain with them for very long, since the conditions were only going to get worse where the sperm whales had been located. The sperm whales were not easy to spot in between the white tops of the waves, but I did manage to get a couple of fluke photos. Whether this was part of the same group as yesterday morning, I don’t know. But the two individuals I photographed do not appear to be in the catalogue. On the way back, we headed in closer to the coast to find some shelter. We also found at least 1500 spotted dolphin! They were small pockets that appeared to be feeding on baitballs and the group was very spread out, all heading towards the west.

In the afternoon, we headed out to the south of Pico, where the mountain blocked some of the wind. Only dolphins had been spotted when we left the harbour. First up was the group of bottlenose dolphins that has been seen for the last couple of days, with the calves. A couple of the individuals look quite scarred up from interactions with other bottlenose dolphin. One of the juveniles did a huge spyhop (head out of the water), but I only caught the very last part as it was sinking back down into the water. Then it was onto a couple of groups of common dolphin. The first group appeared to be feeding as they moved towards the west, with a lot of common terns flying overhead, hoping for scraps. The second group was headed in the direction of the first group! Then came the shout over the radio “Blows”! The lookout had seen a sperm whale. So we raced offshore to the southeast. We didn’t arrive in time to see the first fluke, but over the hydrophone sperm whale clicks could be heard, so we were in the right area. It took a while, but eventually two whales came up and as they double fluked, I identified the 2014 calf of “2776”, yes you guessed it, from “Whitehead’s” group. Another whale popped up, this time it was Whitehead herself. Then we had a long bumpy ride back against the waves to Horta.

There are a few days of windy weather now, so onshore entering data into the SEAFARI App, so there will be a nice map for all the August sightings.

On 24 August, I received sad news from Pico, the harp seal has died in Lajes do Pico. Hopefully a necropsy will be done to determine what was the cause of death. There was some speculation that maybe it was dehydrated, since in addition to water from their prey, they eat ice when in their normal habitat. So a very sad ending to an unusual encounter.

Azores: An unexpected visitor

After a few days ashore due to windy weather, I was finally back on the sea on 19 August. The weather was still not very settled. We managed to find the “Whitehead” group off the south of Pico in choppy conditions. I managed to photograph one fluke, which was of “2776”. The other whale was not in a good position when it dived to show the markings on the trailing edge. I believe that I caught a glimpse of the small nicks of “2776’s” 2014 calf, but don’t know for sure. We did not spot any dolphins, probably more down to the choppy seas, than absence of animals.

A lone harp seal has been observed on the coast of Faial! This seal species is normally much farther to the north in countries such as Canada, Greenland, Iceland and Norway. It is a male at 1.8 m. Some people from the environment department have been to see it and do not believe it is in a poor condition, so will not intervene at this point. I think it looks a bit thin, but they will be monitoring it as long as it remains near the coast of the island. I managed to see it on 21 August in Porto Pim Bay. The officials watching it said when the tide came in, it left the rocks, but luckily, just as I was going to leave, it came back and tried to haul out again. These islands are not very easy for seals to haul out in most places, with their rocky shorelines, but there are a few easier places, such as the boat ramp in Castelo Branco and the sloping rocks around Porto Pim. I do not know how long it will stay, so I was very pleased to get a glimpse of it. This is only the second record of a harp seal in the Azores. The previous record was a dead animal that washed up on the coast of Pico in 2002.

In the afternoon of 21 August, I was back to the north of Pico and we saw feeding sei whales with hundreds of spotted dolphin. You can just see a snipe fish that got away in the photo of the lunging sei whale! Also seen was the group of sperm whales that has been here since the end of May, including one individual I hadn’t yet seen this year. I guess there is plenty of squid around for them to eat, if they are sticking around this long.

The weather looks good for the weekend, but deteriorates next week again, I guess winter is coming! I bet the harp seal is hoping for some cooler weather.

Azores: New group of sperm whales, finally!

On 10 August our start was a bit delayed, because the lookouts had not seen any whales due to poor visibility and rain at the start of the morning. Just as we were about to pack up and go home, a boat on the way offshore to a dive site spotted some sperm whales to the south of Faial. Since there was going to be a small lee in that area, we decided to risk it. The lookout that was in the north of Faial, re-located to the south to help. We caught up with the whales, just as they were entering the lee and we followed them until they were just about to leave it, perfect conditions! I didn’t recognise the flukes when the whales dived and in the afternoon confirmed that this is a new group that has not been seen before. It will be nice if we can see this group again, because there were several individuals, that I missed getting ID photos of.

Back out on the water on 12 August, to the north of Faial. It appeared that there was a group of four individuals, but towards the end of the morning, a lookout went to the north of Pico and saw some sperm whales closer to the shore. We got those in the afternoon. It turns out another one of the well-known groups from the south of Pico is starting out in the north of the island this year! We also had some large groups of spotted and common dolphin feeding on small bait balls. In the afternoon, there was a group of bottlenose dolphin travelling and socialising towards Faial, making some amazing leaps.

On 13 August we were again in the north of Faial. The same whales from yesterday morning were still there, we saw two whales twice and one that was making a bit shorter dives, three times. The lookout then spotted a very large group of striped dolphin. They were “flying” across the water. They were also avoiding the boats as they normally do, unfortunately, one of the boats kept chasing them at high speed, breaking the group up into three parts, so we never got very close, since we did not want to add to this stress. In the afternoon, back to the north and the same whales, but there were now four individuals, at one point socialising. We left the social group and went to find the ones that were diving. When we were a very long way away from the social group, we saw some breaches, leaps out of the water! There was even a double breach!! I have a long lens, but not long enough to capture those images in focus, unfortunately. There were also groups of spotted and common dolphin too. The spotted dolphin were travelling to the west, while the common dolphin were headed in a more easterly direction.

On 14 August we spent the morning to the north of Faial, with the same group of sperm whales that has been here since the end of May, a couple of feeding sei whales and hundreds of spotted dolphin along with small group of bottlenose dolphin. In the afternoon, the sperm whales to the north had moved out of range, so we headed to the south of Pico, where we found that the “Whitehead” group of sperm whales is still around! There was also a small group of spotted dolphin travelling to the west, not very interested in the boats and we came across a very large group of bottlenose dolphin on the way home. At one point, several dolphin started leaping high into the air in different parts of the group. It was amazing to see dolphin jumping 5-7 m in the air!

Some windy weather is headed our way, so will probably be on shore for a few days now.

Azores: Sperm, sei, pilot whales & spotted dolphin

Sei whales stole the morning on 6 August. We had to wait a bit for confirmation that there were whales and we headed towards an area where sperm whales had been seen. But in between the time we left the harbour and arrived to the area, a few sei whales had moved in! We saw four in total, a group of three that split into two plus one, and another single. One of the sei whales had a hole in its dorsal fin, which will make it a little easier to identify when matching fin photos.

The sperm whales were playing hard to get, with the calm conditions making the blows all but invisible. “Blow” shouted the skipper of one of the boats, only for us to see a fluke rise in the distance where the last blow had been seen! The first and last blows are usually the most powerful and visible in the sequence.

So we headed offshore to see some dolphins, but only about two minutes into watching a group of spotted dolphin, the lookout directed us further out to sea. We missed one whale, but he said there was another and we managed to see Whitehead show her tail. After that we decided to start making our way back to the harbour. On the way, we were waylaid by a group of spotted dolphin, then a small group of bottlenose dolphin and lastly a large group of milling pilot whales. There were loads of small babies in the group, swimming next to their mothers.

After lunch, we had a bit more luck with the sperm whales, although we did have to wait a bit, since we arrived just after one of them had dived and since they can spend up to 55 minutes on a dive, we were lucky to only have to wait for about 40 minutes! We got two different flukes from the Whitehead group and then started to make our way back, trying to find some dolphin. We didn’t find any dolphin, but we did find a group of beaked whales that were not too shy and so we managed to watch them for about five minutes before they disappeared into the waves. Since the wind was getting up, we made our way slowly back to Horta.

On 8 August, I was out in the afternoon, in the north of Faial. The same group is still hanging out there! We saw one fluke and then found a socialising group of three that turned into four. There were some heads poking out of the water and one side fluke, when a whale is swimming on its side. After a few shallow dives from the group, another whale appeared on the surface. This one also shallow-dived and we thought they were going to join together and socialise, but in the end they all fluked! Two individually and another two fluked together! Altogether, I got six flukes from the group in the end. We didn’t see any dolphins, but did come across a juvenile hammerhead shark and a devil ray. While picking up some plastic trash, one of the guides got stung by a strand of Portuguese Man O’ War tentacle hanging onto the box. Not a very nice thing to experience. She could feel the effect all the way up her arm and into her jaw and chest. As soon as we arrived back to the harbour, she put some vinegar onto the sting, which is supposed to help a bit, but as a precaution, we also went to the hospital to get her checked out. Portuguse Man O’ War have one of the most poisonous stings of the jellyfish and although not usually deadly, it can cause quite a bit of discomfort and pain.

On 10 August there were some scattered rain showers around, which dampened things on the boat. The sea was flat calm for a while, making it difficult to spot any blows. But the Whitehead group was found in the end and I even got a fluke of Whitehead herself. While we were waiting for another whale, we headed out to some spotted dolphin and a sei whale turned up too! Then the showers came, so we decided to watch the dolphin a bit longer and then head for Horta, where the sun was shining. Just before we got to the Faial/Pico channel, we came across a group of fast moving spotted dolphin. The sunshine and the backdrop of the islands made for some nice photographs of the leaping dolphin! They were heading away from home, so after 10 minutes we turned back for home ourselves.

Azores: Sightings still going strong

On 27 July we had one of “Nike’s” group north of Pico, in the morning. It was the 2010 calf of Nike, which we saw twice. We did not see any other individuals of the group, although we could hear them clicking. I doubt it will take the Nike group very long to get to the south of Pico where they usually hang out. Finally, this afternoon, Whitehead decided to show herself on the south of Pico! She was hanging out with a few of the Winter Whales, although she was headed west, while the others were headed east, so maybe it was just two groups passing each other. One of the Winter Whales was curious about the boat, circling us three times! Loads of spotted dolphin around and a solo sei whale too! Have you ever seen a whale “footprint”? As the fluke moves, when the whale is close to the surface or when diving, the water gets disturbed and leaves a smooth circle where the whale has just been. And I can’t forget the “bowriding” hammerhead and a small group of devil rays to top things off!

On 28 July we were again back to the north of Faial. The lookout had spotted some sperm whales and spotted dolphin. The mother & calf did a double fluke! The calves only begin to dive at around two years of age, so this one was learning the ropes. These two whales appeared to be the only ones up there, until we were getting ready to leave, since it didn’t look like the whales were going to dive a second time, when out of the blue there was a breach of a sperm whale a mile further out to sea! We then headed closer to the coast where there was a large group of spotted dolphin socialising. A few of the younger animals were leaping occasionally. It is pretty amazing how bendy the spotted dolphin is.

Too windy on 29 & 30 July, giving me a chance to catch up on some paperwork.

We were back out on 31 July in some challenging conditions. But those conditions can sometimes be good for taking photos, if you catch the right moment! The Whitehead group is still around, although they were a long, long way from Horta today, heading to the eastern end of Pico. I managed to get four of the individuals. I guess since Whitehead herself showed herself the other day, she didn’t feel the need to check in today.

Hard to believe August has arrived already. We were back to the south of Pico again. There are still sei whales around, also a large group of pilot whales and sperm whales too. A tiny bottlenose dolphin calf and a high-flying spotted dolphin was part of what appeared to be a mating group.

On 2 August we got word from the vigia in the north of Faial that sperm whales had been seen up there, so off we went. It turned out to be a group that was seen on 28 May and was first seen in 2009. After a few flukes, including a couple of individuals that hadn’t been seen in May, we headed for some pilot whales. The group was quite spread out in smaller groups of about 20-30 and appeared to be resting. There was a fairly newborn calf in the group, since foetal folds were visible on the flanks. A sei whale was also close by, although was a bit elusive to the boats, moving quite quickly in various directions. We could see the power of the blow emerging from the blowhole. On the way back to the harbour, a small group of spotted dolphin were also seen. They were feeding on some small baitballs close to the surface. It wasn’t clear what they were eating. In the afternoon, we were also back to the north, but the wind had increased, decreasing blow visibility. The lookout did manage to find one individual, but it wasn’t diving. At first glance, it had a white scar on the right side and it looked a bit like Nike’s calf, which had been seen in this area a few days ago. But on a closer look, it wasn’t the same. We also saw what was probably the same sei whale from the morning, doing the same thing and a small group of spotted dolphin.

The weather has turned a bit windy again, so hopefully a bit of time to check out the new sperm whale flukes with the matching program.

You can see all of the 295 July sightings on Seafari App sightings July 2020.

Azores: Cetaceans galore

We had a full day out on the catamaran on 24 July.

The lookout to the north had seen a couple of sei whales, while the lookout to the south had only seen dolphin. By the time we got to the north, the sei whales had disappeared. But there were hundreds of spotted dolphin feeding on horse mackerel along with Cory’s shearwaters. After watching for a while, we carried on a bit further offshore to one of the areas that is usually good for finding sperm whales. Just after hearing some sperm whale clicks on the hydrophone, we came across a loggerhead turtle eating a piece of squid! That squid was probably vomited by a sperm whale, so we knew we were on the right track. When sperm whales eat squid, they do not digest the beaks. After a time, the beaks become uncomfortable and the whale will vomit to get rid off them. By default, anything they have recently eaten will also come up, so we sometimes see chunks of squid or deep sea octopus at the surface when sperm whales have passed by.

At the end of the squid crumb trail we found a group of socialising sperm whales. One individual did four breaches and the juveniles and a calf were lobtailing and throwing their tails around in a social group. Unfortunately, when the whales are socialising, they do not usually show their flukes, since they aren’t diving. I managed to get one fluke of one individual that did make a deep dive at the very start of the encounter and then got the same fluke as she dived in preparation for a breach. It appears that she could be pregnant, looking at the size of her belly visible in one of the breaches. Sperm whales breed all year, since they do not depend on migrating to warm waters to have their calves. I guess if she is around later this year or next year, we may have our answer, if there is a small calf with her. She was accompanied by a calf in the suckling position before she dived the first time. Sperm whale females will suckle another female’s calf, since they live together their whole life, the favour will be repaid sometime in the future.

We also had a group of over 500 spotted dolphin feeding on mackerel along with 1000 or so Cory’s shearwaters. One individual had a lot of barnacles attached around its mouth. I have seen this occasionally on bottlenose dolphin and do not know if they have an impact on the dolphin’s ability to feed; this one certainly did not look skinny. This seems to happen when there is an injury to the jaw and the teeth become exposed for the barnacles to attach to.

On 25 July we managed to avoid most of the rain showers and followed the lookout’s directions to four feeding sei whales accompanied by spotted dolphin. There is a lot of bait fish around for the sei whales to eat, which is why they are hanging around. Then it was out to the area where the sperm whales were. Out there, we also found another sei whale and striped dolphin too. The sperm whales have been seen before, one in 2015, another last year and the third one on 7 July. I thought I recognised one of the sei whales from the other day, but although the dorsal fins are similar, they are not the same. We also stumbled across a small group of Risso’s dolphin on the way to the whales, but were not able to spend much time with them, since the lookout kept telling us to get a move on!

The weather did not co-operate for a full day on 26 July, but we had a fantastic morning.

We started with a small group of spotted dolphin on the way to sperm whales. We just missed two flukes by 10 minutes, so we had to wait a bit to get our first whale. It turned out to be “2578” one of the “Whitehead” group. We saw another individual, but it fluked in a wave, so no ID on the second individual. It was quite bouncy out where the sperm whales were and they were heading into the waves, so we headed back towards shore where the lookout spotted a sei whale with some dolphin.

It turned into an incredible sighting of three individuals, including a mother & calf. The calf showed a bit of interest in the boat, with the mother patiently waiting for it to go back to her! There was a sighting of a mother & calf sei whale a couple of days ago in São Miguel, about 125 nm away from Horta. I have sent the dorsal fin ID photos of one of the biologists over there to see if these are the same individuals. Most sei whales passing through the Azores are headed towards Labrador, based on some tagging done by the University of the Azores, but there seem to be some individuals that do not make the long trip, instead preferring to find fish further south. At the moment, there is quite a lot of baitfish around here. They were seen feeding on snipe fish a couple days ago and we saw some mackerel bait balls in the north of the island two days ago.

There is a bit of wind arriving later this week, but until it arrives, I will be going out to see what is around. There are a few whale watching tourists around at the moment, which means that the support from Biosphere Expeditions will last a bit longer, if I can hitch rides with them.

Azores: Fantastic weather & sightings

The weather is fantastic, long may it last! There are still daily sightings of sperm whales and on 21 July, I re-sighted three individuals from the “Winter Whales” group. Two of this group were first sighted on 22 May, so they have been around for quite a while. I have started thinking that maybe this group tends to stick around the Azores all year round, since we have had now had sightings of them in spring, summer, autumn and winter, although not always in the same year. I don’t know where the other members of the group were today, but my colleague from Lajes had said they had been seeing the group a week ago.

We also had sightings of a small group of shy bottlenose dolphin, spotted dolphin, a group of elusive Risso’s dolphin and a huge group of travelling common dolphin, almost an unbelievable sight as they came towards and then past the boat. There were some very tiny newborn babies leaping alongside their mothers as they went. One dolphin kept leaping and crashing down onto its right side. Sometimes this behaviour is to try and dislodge a remora, which has attached itself to the dolphin, but in this case, we couldn’t see any.

On the 22 July we had another calm day, although a bit overcast. The lookout directed us first to a group of dolphin feeding alongside a couple of sei whales. One of the sei whales appeared to be skim-feeding on one occasion and also did a couple of lunges. We did see one small bait ball and it is likely they were feeding on horse mackerel. We then moved on to the sperm whales, although were interrupted by another sei whale! And after a few flukes, we headed over to some dolphins, then spotted a blow and first thought was another sei whale, but no, this was a sperm whale that surfaced just behind a group of dolphins! This whale has a very distinctive fluke, with a curlicue left end. This whale, “1702”, was first seen in 1993! It has also been seen in 2011. The other three animals had been seen on 3 & 4 July this year.

We finally had a change of scenery on 23 July and were able to get to the north of Faial. A lookout that is usually on the south of Faial, changed his spot. It paid off! There were a lot of sperm whales about 3-4 miles offshore, including a brand new baby. This calf had probably been born over the last few days, the tail and dorsal fin were still floppy! We could also see the foetal folds very clearly, another indication of a very young animal. When its mother finally dived, the little calf came over to investigate one of the whale watching boats, unfortunately, not ours! We were quite green with envy as the calf circled the other boat three times. When the mothers dive, the boats are the biggest thing left at the surface and I think that sometimes, the new babies are confused and think we are another whale! The mother of the calf was seen last year, the others have not been seen previously.

There was also a single sei whale that appeared to be resting or travelling slowly to the northwest. We also came across a shy or deep-feeding group of bottlenose dolphin, which were making dives of 3-4 minutes. We also saw a huge pod of striped dolphin, probably at least 750 animals! They appeared to be travelling to the northwest and avoiding the boats, as they usually do.

Germany: final day deliverance

The last day delivered!  Three teams collected 12 scat samples, four of which were fresh enough for genetic analysis.

So in summary, over the seven days of our community expedition, we

  • walked about 250 km on foot and rode once by bike, an average of 14 km per group per day, as always on publicly accessible hiking trails as well as agricultural or forestry trails
  • covered 15 cells of the pan-European 10 x 10 km grid
  • identified 163 wolf scats in the field, 54 of which we collected for nutritional analysis and 7 of which were fresh enough to qualify for genetic analysis, the remaining 109 scats were too old or broken up for analysis

Scats for nutritional analysis will be sent to the University of Veterinary Medicine Hanover, Foundation and the genetic analyses will be performed at the Senckenberg Institute.

It will be very interesting to see what “our” wolves have eaten and whether their pack composition has changed, the territories have shifted or evidence of reproduction can be gleaned from our samples.

So all in all we achieved a lot under this year’s difficult conditions of reduced time, funding and helpers due to the absence of our usual teams of international citizen scientists. But still, we were able to determine in which areas the wolves are not roaming at the moment 😉

Wolf commissioner Kenny is scheduled to investigate the remaining areas in the next few days to have a closer look where the wolves are now. Good luck, Kenny!

We would like to thank all supporters who made this community expedition possible – especially Biosphere Expeditions for the funding via their coronavirus appeal, their logistical support and equipment. We would also like to thank the wolf bureau at NLWKN, the Lower Saxony State Forests and, of course, our fellow wolf commissioners and helpers for their support. A very special thanks goes to Kenny and his Biohotel Kenners Landlust for their flexibility, accommodation and fantastic food.

We look forward to a ‘normal’ expedition in 2021.
