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.
