Staring down the blow hole

Hello readers, its Kelly here and I’m back with another update about life at sea aboard the Cap Finistére as a Wildlife Officer Placement.

This week had a lot to live up to after the array of species and sightings the week before. It started out with a beautifully calm channel crossing on Wednesday (12th July). The sun was out in force and the gannets were circling over the ripple of common dolphin fins hunting below the surface. Feeding had definitely taken priority over putting on a show in the pressure waves, as group after group of dolphins seemed to keep quite a low profile as the ship sailed past.

The crossing had been quiet and with the other ships dotted around the channel we thought our chances of spotting anything would be slim. Just as the glare was disappearing and the sun was lowering in the late hours of the afternoon a fin broke the surface and the silence. It belonged to the first minke whale I’d ever seen! It vanished as soon as it was noticed, giving me a new understanding of the nickname “slinky minke”. It was definitely a good omen for the start of what would hopefully be a week full of sightings.

Thursday morning greeted us with fin whale blows from our bedroom window, beckoning us out and onto deck 10. The deck watch started out early but the promise of fin whales seemed to have passed us by being replaced with grey clouds and dark skies. Fishing vessels materialised along the horizon one after the other until there were around 40 boats surrounding us. Half way through the quiet deck watch a pair of skittish common dolphin surfed alongside the ship. The dolphins seemed to have brought the sun and soon the clouds were replaced with sunshine and the tail end of a rainbow. In the last few moments of the watch the whale blows were back and soon after the blows were seen a fin whale rostrum was seen breaking the surface along the horizon. A pod of nearly 60 common dolphins swam by just in time for the end of the deck watch.

Up to watch the sunrise and keen to spot some of the recently seen orca (on ORCA’s most recent Sea Safari) we were up and on deck for 05:00 on Saturday. The day was off to a great start, with sightings of around 25 common dolphins and several whale blows along the horizon. Four brown fins bobbing along the surface interrupted the fairly tranquil morning and upon closer inspection they turned out to be Cuvier’s beaked whales! These weird and wonderful cetaceans are quickly becoming a firm favourite as it feels like an absolute treat every time I spot one. This particular pod of whales was spotted much more north in comparison to their usual range in the trenches, canyons and deep sea along the Spanish coast.

The deck watch had even more tricks up its sleeve; in the last third a whale blow was spotted near to the ships bow. This blow was tall but thinner than the fin whale blows I’d seen previously and much to my surprise the whale surfaced close enough to get a good look at its curved but very upright dorsal fin. It was a Sei whale! Just when I thought my day couldn’t get any better we sailed past a very large surface disturbance, the whale couldn’t have been that far away as it looked quite recent. Out of the blue (quite literally) the head of a fin whale appeared and vanished, but not before I managed to see the whale open its nostrils to exhale and get a good look down both blowholes!

The beautiful sunset on Saturday morning.

Sunday along the Brittany coast was the calmest sea state I have ever witnessed during my time on board. The sea rivaled glass and was accompanied with a thick curtain of fog. It was grey, visibility was poor and the GPS for the logger decided to take the day off forcing me to go old school and record any sightings on paper. Pods of common dolphins made up for bad weather and cruised alongside, busy hunting and feeding on nearby shoals of fish. It was a dolphin sort of morning as the resident pod of bottlenose dolphin came out to play! The fog ended up being a blessing in disguise as the ship was forced to slow down to an average of 10 knots, allowing the dolphins to get close enough to leap and play in the bow waves.
Both bottlenose and common dolphins were out again on Monday along with the largest bony fish of them all – the ocean sunfish!

These weeks have been a marine biologists dream and have allowed me to get a sneak peak into the activities of marine mammals and other cool creatures in and around the Bay of Biscay. I’ve been lucky enough to see so much in such a short period of time during this wonderful and inspiring placement. I hope to spot even more cetaceans during my last week but who knows what I’ll see next!

Until next time,
– Kelly (Wildlife Officer Placement)

Introduction to life at sea

Hello readers, I’m Kelly the first Wildlife Officer Placement (of the year) on-board the Cap Finistère vessel, which is run by Brittany Ferries.

Kelly and Hazel Wildlife Officers

My first day (Wednesday, June 26th) was a whirlwind of activity on the ship, all the new sights, smells, names, faces and corridors to get lost down. No time was wasted as Jess and I got straight into meeting and greeting passengers and informing them all about the wonderful opportunity to spot cetaceans with us. Unfortunately the weather had other ideas and our deck watch plans were very much rained on. The weather went from bad to worse, with a majorly rough sea state rocking the ship and inflicting bouts of seasickness in the passengers as well as the seasoned crew, but not us hardy Wildlife Officers!

Over the next few days, the storms had cleared, the sun was shining and the common dolphins were out in significant numbers. My first sighting seemed almost magical after a rocky start to the placement – the dolphins bow riding and playing in the wake of the ship more than made up for it.

Thanks to Jess’s time and patience, I got to grips quickly with our schedule, the logger, administrative tasks and being able to identify cetacean species from a fast moving vessel.

Other things I managed to do in my first week included:

  • Acquiring my sea legs.
  • Navigating my way around the ship.
  • Correctly identifying common dolphins.
  • Entertaining and inspiring children.
  • Getting a sunglasses tan.
  • Debating the largest sea creature: megalodon vs. blue whale.

Week 2:

Time flies when you’re having fun, and before I realised it was Wednesday again. The week brought new cetacean sightings and a new wildlife officer into my life. Patience and perseverance really does pay off and on mine and Hazel’s Thursday morning deck watch, after hours of staring at the sea we (and a very keen passenger) were rewarded with a super pod of common dolphins. Wave after wave of dolphins came bounding towards the ship and I honestly couldn’t believe my eyes when we saw what must have been nearing 200 individuals, mothers and their calves and even the odd striped dolphin tagging along.

The day just proceeded to get even better as the second deck watch of the day conjured up a kaleidoscope of cetaceans – even more common dolphins followed by pilot whales and a Cuvier’s beaked whale extremely close to the ship that quickly dived into the depths. I thought my day had been made, and that it wasn’t possible to get any better than that until out of the corner of my eye after a long but exciting day I spotted a lone, tall, jet black, straight dorsal fin just cruise through the water – we can’t say that it was definitely an orca but it sure seemed pretty convincing.

IMG_1943

Friday morning’s deck watch was my first introduction to identifying mysticete whales from their blows. I was treated to two quite tall and straight blows from fin whales close to the horizon and the tiny sliver of one of the whale’s backs just breaking the waters surface.

Little did I know that the fun was only yet to start, as Saturday turned out to be everything I expected and more! Pod after pod of common dolphins graced us with their presence and far away fin whales teased us with their fleeting blows. A pod of five mystery uniformly coloured individuals had us wracking our brains in order to identify them, until a passenger was able to put our minds to rest by showing us a slow motion video he had taken – they ended up being five quite large bottlenose dolphins.

The evening deck watch had even more tricks up its sleeve, the weather had calmed, the sun had come out and the conditions were just right for cetacean spotting. It turns out that we couldn’t have missed our next sighting if we tried, as massive fin whale rolled the last third of its body back into the watery depths right beside the ship! The whale’s presence seemed to have halted time and attracted quite the crowd as the amazing animal slowly appeared and slipped away into the shadows.

Saturday couldn’t have been topped and Sunday morning was slow and quiet. The usually serene and relatively uneventful coastal waters along the Brittany coast surprised us with a few cheeky common dolphins hunting around a fishing vessel and a shy harbour porpoise making an appearance for the first time during my time on board.

My time on the Cap Finistère has been extremely exciting so far; adjusting to the way of life at sea and also being able to see these beautiful cetaceans up close and personal has been nothing short of inspiring.
I hope to keep sharing my discoveries through blog posts and pictures, as I know this only the beginning of a wonderful new adventure!

The half way mark!

Hello! Jess here reporting on my final week on board the Cap Finistere. At the start of the week I was joined by Kelly, the first of our three Wildlife Officer Placements. These placements are designed to give people a four week experience on board learning how to be a Wildlife Officer.

Our first crossing to Bilbao saw the worst weather I have ever experienced in the Bay of Biscay! We were unable to go out for our surveys as the spray of the waves was coming over the top of the ferry and landing on the deck. On our second crossing we did manage to venture out, but the sea was still a very rough sea state 5. Despite this, we did catch fleeting glimpses of common dolphins and striped dolphins.

We had a very scenic trip to Santander on Saturday where we spotted some large birds of prey. Are there any readers out there who know what feathered creatures might be lurking in the sky around the city?

IMG_1798

Approaching Santander

Tuesday’s crossing brought more common dolphins all through the afternoon as we approached the continental shelf, AND A WHALE! Finally! I was starting to get worried about the lack of whales this week but a small fin whale made an appearance which made my day!

As we are half way through our Wildlife Officer season on the Cap Finistere, I thought I would write about some of the things we have achieved so far, and have included pictures of some of my most treasured moments on board.

IMG_1780

Common dolphin

From the end of March until now we have engaged with an outstanding 8370 passengers! That’s through giving presentations, delivering quizzes, running children’s activities, and deck watches. Amazing! We’ve met some cracking passengers this year who have been inspired by the wildlife in the Bay of Biscay and have been very supportive to ORCA and its aims.

IMG_9839

Common dolphins

We have signed up twenty six adults and children as ORCA members and FinFriends, and our generous passengers have donated over £2,000 to help us run our conservation projects!

IMG_9835

Acrobatic common dolphins

It’s great to see the numbers, but the comments and feedback from passengers is what really makes me feel excited to be a Wildlife Officer. I met some parents travelling back from Spain who were keen to tell us what they had been up to on holiday. Turns out, their children were so enthused by our presentation on whales and dolphins, and the huge issue of plastic pollution in the sea, that they spent their entire holiday cleaning the beaches they visited! Two passengers persuaded me to seriously consider a career in teaching, after their kind comments about a presentation I gave. I am now looking into doing my Forest Schools qualification as a result of meeting them! I also had a brief encounter with a man who was convinced he could smell seals from miles away. Nothing profound came of this, I just wanted to share it as it still makes me smile.

Comments such as ‘I never knew a killer whale was actually a dolphin’ after a presentation, and ‘that was magical’ after a dolphin encounter,  have made me incredibly happy, knowing that what we do on board is educating and inspiring the public to care for and protect our oceans.

That’s it from me, but wait! I can’t go without mentioning my two incredible colleagues Hazel and Katie! These two women have been inspiring to work with, and are professional, hardworking, innovative, and dedicated to saving our seas. I know they are going to go onto great things, and of course our Hazel will be on the Cap Finistere until September, so you shall be hearing lots more from her!

I want to thank all who I have worked with at ORCA and Brittany Ferries, and I wish you a very successful summer full of whales!

There and Back Again

Sophie here, checking in from the final week of Wildlife Officers on board the Pont-Aven.

Our last week coincided with the first of ORCA’s Sea Safari trips running this year. It’s my first sea safari, as Andy and I were two of the Sea Safari guides for the duration of the mini-cruise. It was wonderful to be involved and we had a great set of interested passengers booked on for this trip.

Nigel Marven, as one of ORCA’s patrons, also joined us alongside our team of ORCA guides, and Wednesday evening we were able to hear him speak about his travels, work and some of his amazing cetacean encounters during the course of his career. From being towed along with a pod of Belugas to stroking grey whale calves, there were definitely some inspiring encounters!

sdr

A fascinating talk by Nigel Marvin with many attentive listeners

Despite rather rough weather as we approached Spain we had a productive trip with 5 different species definitely identified and 312 individual cetaceans counted. We had lots of common dolphins coming into the ship (282 total for the trip) which always delight, and photos afterwards confirmed there were a few striped dolphins dotted about the pods as well. We also had groups of bottlenose and Risso’s dolphins which were spotted by passengers out the restaurant windows! So whenever you’re on board Brittany Ferries, don’t forget to look out the window even when you’re eating, because you’ll never know when you get a great sighting.

IMG_9163 (2)

It wouldn’t be a crossing without our lovely common dolphins

Of course, everyone was desperate to see a whale, despite being entertained by dolphins aplenty. While we did have a very distant whale sighting, it was not identified, and it only made us even keener to have a closer sighting. Fortunately, after lots of scanning the seas, the benefit of having so many eyes out looking was clear as we had a fantastic sighting of two fin whales together, clearly visible from the ship.

Unfortunately we had a considerably bumpy night as we sailed back towards the UK. However, the next morning we still had a fun trip heading north, with some dolphins and views of the lighthouses of the islands around the Brittany coast. We also had our ORCA quiz to test our passenger’s whale and dolphin knowledge, with some ORCA cuddly toys and t-shirts for first and second prize. Nigel Marven also added his own tie breaker question for second place. “Which animal has the largest penis in the animal kingdom, relative to body size?” For those of you wondering, it’s a barnacle of course! The length is an adaptation to a stationary lifestyle. So if you need a fun fact for a dinner party conversation, there’s one for you.

If you are interested in joining us on a Sea safari and would like to find out more about them, you can find information on ORCA’s website here, and on Brittany Ferries website here.

As the rest of the Sea Safari guides departed the ship, Andy and I were left for our last crossings to Cork, Roscoff, and across Biscay before leaving the Pont-Aven. We had one last crossing to Cork with a couple of quite large sunfish, which were our first this season for the Ireland crossing. I love sunfish, so I was glad we had a few to say goodbye to.

This Sunfish was quite a large specimen, at least a meter long!

Our last Biscay crossing was very smooth, and we had many whale blows in the distance, we even had a fin whale blowing some 800m from the Pont-Aven, which we were able to enjoy with lots of Spanish children on a school trip. We also caught one lone Cuvier’s beaked whale sneaking past the ship. The number of whales is picking up, so hopefully there’ll be even more for the upcoming Sea Safaris this year.

He nearly slipped by, but we managed to spot this male Cuvier’s Beaked Whale

All too quickly however, we have reached the end of the final week and the Wildlife Officer 2017 season aboard the Pont-Aven. Thousands of passengers and cetaceans later, I know I speak for all three of us when I say that we have had a fabulous time looking out for whales and dolphins aboard Brittany Ferries’ Pont-Aven. I have been so grateful for this opportunity that ORCA has given me. These weeks have flown by so quickly and yet it also seems like that first week in April was ages ago. I have learnt so much and had two amazing colleagues to work with on board. And of course I have been able to see such a variety and number of whales, dolphins, sharks and sunfish, and even a dead giant squid. You never know what you might find!

IMG_1777

Looking out for whales and dolphins! It’s not ORCA’s motto for nothing!

We all met such a diversity of people on their travels, from professional truffle hunters to Israeli students fascinated by Celtic music to families incorporating cetaceans into their homeschooling. Bikers, families, school groups, business trips and lone adventurers, different languages, different cultures, different political views, we are all one human family, connected to the ocean in so many ways. It’s been great able to talk to and educate so many different people about the importance of cetaceans and their ocean home.

And so, we bid you farewell from the ORCA wildlife officers of 2017, on board the Pont-Aven. You’ll still be reading a few more blogs from me, as I will be moving to the Cap Finistere till September!

From Heather, Andy and I, we wish you safe travels, fair winds and good sightings!

Farewell from the Pont-Aven Team!

A dolphin comes to port

Hazel here again for this week’s blog post! It’s week thirteen for us Wildlife Officers aboard the Brittany Ferries Cap Finistère; here’s an update of on our recent sightings.

The week got off to an emotional start as Jess and I bid farewell to our colleague Katie, whose three month position came to an end last Wednesday. After a brief goodbye in the ferry terminal, Katie headed for home and Jess and I left to board the ship. I must say the Cap Finistère feels quite homely to me now after three months working and living aboard on a two weeks on, one week off basis. We enjoyed a warm, sunny afternoon for our deck watch that Wednesday afternoon, but had no cetacean sightings.

Our two deck watches on Thursday more than made up for this with lots of lovely common dolphins and striped dolphins sighted. An arched back and curved dorsal fin was our first sighting of the day, which occurred on the Northern edge of the continental shelf in the Bay of Biscay. This was recorded as a ‘medium cetacean’; our first instincts were that it was minke whale, but we weren’t sure about the likelihood of seeing one in this area. Sometimes the best we can do is try to capture a photograph of sightings and consult our more experienced ORCA colleagues back in the office at the next opportunity to do so.

In cases such as this when we are unsure or in disagreement regarding an animal’s identity, in the interests of collecting scientifically valid data it is better for us to err on the side of caution and simply record the information we have such as the animal’s size and location, rather than to make an inaccurate guess which could result in misleading records. On returning to the office, our colleagues confirmed our thoughts and positively identified this as a minke whale, advising that they are sometimes seen in this area of the Bay. There is so much to learn about these animals, which varies hugely from species to species, and I am relishing the opportunity to absorb so much information about cetaceans.

Minke edit

On Friday we were back in the channel during which we saw no cetaceans. The animals are there, but the species diversity is comparatively less than the Bay of Biscay. Additionally, the presence of shallower water species such as harbour porpoise and minke whales is less obvious than the likes of high leaping striped dolphins or the 8m high columnar blows of fin whales seen in the Bay.

On Saturday we ventured back across Biscay and were treated once again to lovely encounters with pods of common and striped dolphins. At one point I spied a very distant whale blow. I haven’t seen any of the colossal great whale species in the area in the past two months; perhaps this marks the beginning of the fin whales returning to feed in Biscay, as is usual at this time of year. At the moment though, Cuvier’s beaked whales are the most numerous of our whale sightings. This day was no exception as we had the good fortune of a very close encounter with two of these illusive deep diving animals. The conditions were still enough to see their blow as they surfaced to breathe and we marvelled as their chocolate brown barrel shaped bodies rolled gently away through the calm waters.

Cuviers roll

On Sunday we were heading northwards once more. We kept our eyes firmly fixed on the Brittany coastline, hoping to see the resident bottlenose dolphins that we have been fortunate enough to encounter on many occasions on this sailing. Sure enough, as I scanned the waters near the shore and cliffs, the large, steel grey dorsal fins of five bottlenose dolphins could be seen gently breaking the surface of the water. A short time after, three more animals could be seen slowly moving across the shallow waters near a beautiful patch of sandy beach. I observed that people stood on the beach were watching the dolphins from the shore, whilst we were watching from the ship; they would have had great close up views from their vantage point!

Kittiwake

Later that day we neared the port in Portsmouth. I was in our cabin at this point, whilst Jess had ventured outside to take in the view of the seaside city as we came in to dock. The cabin door burst open and Jess flew into view ‘the dolphin is here!’ she exclaimed excitedly. The animal she was referring to is a solitary bottlenose dolphin which has been seen in the area recently, moving between the waters around Portsmouth and the Isle of Wight (although it is now thought there may actually be more than one of these animals in the vicinity). I hastily grabbed the camera and binoculars; knowing how fleeting encounters with cetaceans can sometimes be, I didn’t want to miss this amazing opportunity to get a closer look at this dolphin! My heart was pounding in my chest as I looked across the waters of the port. Jess pointed towards a small boat, saying that she had seen the dolphin riding the bow waves in front of it and swimming alongside it, to the delight of the people within the vessel. A moment later the large, gunmetal grey, curved dorsal fin of the bottlenose dolphin split the surface of the water.

This is the closest encounter I have ever had with a bottlenose dolphin and this finally gave me an accurate impression of the sheer size of these charismatic animals, the largest of which can reach up to 4m in length. I observed the animal breach out of the water, but the only good photo I managed to capture was the above image of the dolphin’s back and dorsal fin next to the little boat. Since this sighting, as a result of a competition by ORCA to name this animal, it has since been dubbed ‘Nelson’! Other locals have also named this dolphin ‘Dinny’ and ‘Spirit’ – who knows how many names the animal will acquire during its time here!

Continuing the variable degrees of success on this week’s deck watches, no cetaceans were sighted on Monday. Once again it was a completely different story the following day with nearly two hundred common dolphins seen Tuesday, including lots of calves.
It was a brilliant end to this two week period on board.

The week finished as it began, with emotional goodbyes; Tori and Dave, some fantastic entertainment managers we have worked with over the past three months, are departing on Friday. We are very grateful to them as colleagues and friends for their wonderful assistance to us – they took a very keen interest in our work and were a huge help in enabling us to deliver our activity programme for passengers. Thank you both very much and bon voyage!

We’re now halfway through our six month Wildlife Officer season aboard the Cap Finistère, which means it’s time for our volunteer placements to begin! We have three placements joining us aboard over the next three months; each one will be living and working aboard with us for a month as we teach them everything we know about working as a Wildlife Officer. I’m excited to work with them and help them to have a fantastic experience with lots of cetacean sightings!

Melanistic common edit

I’m now heading back home for my week off. One of the things I am most looking forward to is heading out at dusk to listen for nightjars. These beautiful, unusual birds have returned to the UK from Africa to breed and I hope to hear their characteristic churring calls on my local heathland wildlife reserve.

I am also doing a refresher course with British Diver Marine Life Rescue (BDMLR) to remind myself of the techniques I learned a few years ago to assist with the rescue of stranded cetaceans. Wildlife Officer Katie is coming along too, so we’re having a little reunion already after she departed only last week!

We’re fast approaching the ideal time of year for fin and sperm whale sightings in the Bay of Biscay, along with orca. My fingers are firmly crossed for these animals to be in the area on my return in a week’s time.

I’ll leave you with another common dolphin image – I never tire of seeing these lovely creatures and I’ll miss them on my week off!

Bye for now!

It’s all fin and games

Throughout our time on board, we have been privileged to witness a truly wonderful range of species, living wild and free throughout our oceans. We are often asked about the social lives of these species, and why they seem to just love to play. We love to talk about their behaviour, as there is so much we are yet to discover about their social lives and communication.

Cetaceans are widely recognised as incredibly sociable, with great emotional intelligence. The large baleen whales live largely solitary lives, often migrating long distances to find a mate. They sing across oceans, communicating over hundreds of kilometres. Meanwhile, the toothed whales, including the dolphin species and sperm whales usually live in very sociable pods. Indeed much of what we know about communication within these species, we have learned from these gregarious and playful animals.

In general, smaller species such as the common dolphin tend to form more flexible societies. Individual small family pods can come together to form a huge group of hundreds or even thousands of individuals all hunting and playing together. They are so sociable that they often form mixed pods with other species. We often see striped dolphins and common dolphins travelling and playing together as we travel through the Bay of Biscay.

dolphintrio.jpg

Common dolphins coming to play by the Pont Aven

Larger cetaceans such as the orca and pilot whales tend to form stable matriarchal pods. These are led by the eldest females, the matriarchs of the group. These family groups often stay together for their entire lives. This means that they are incredibly close, with strong emotional ties within their pod. They will be part of a wider population, able to communicate and mix with other related matriarchal pods.

pilots, northern shelf, June 17

Pilot whales sighted last week from the Pont-Aven

These family pods have very strong, individual identities. That can be seen through their communication. Different family pods belonging to the same wider population have many similarities in their dialects. The more distantly related they are, the more different their whistles sound.

You can however have different populations living in the same area, yet they don’t mix, as is the case for orcas and sperm whales. Their dialect is completely different, and so they can’t communicate with the other populations. The unique dialect they each have really reinforces their sense of identity and knowledge of who they are. When it comes to orcas particularly, there are many different, genetically distinct ecotypes of orcas throughout the world.

They also have distinct identities within their own pods. Dolphins are known to use signature whistles to refer to individuals, in the same way as we have names for each other. These are thought to change throughout their lives, for example when young male dolphins leave their mothers to form young ‘bachelor pods’ their signature whistles become similar to each other. This is thought to strengthen the bond between them, and to signal to competitors that their alliance is strong.

Although it can be difficult to understand the reasons for many behaviours, sometimes it is simply play. We have seen dolphins jumping into the air, twisting and turning and chasing each other under the water. On every crossing of the Bay of Biscay this season, we have had dolphins darting through the water, keen to play in the waves around the ship, and to surf the wake.

In other parts of the world they have also been recorded playing with objects such as pebbles and seaweeds, balancing them on their pectoral fins, carrying them around in their mouths, or throwing them back and forth to each other. We don’t understand the rules, but I’m sure it’s all great fun from the dolphins’ perspective!

Dolphins have also been recorded using tools. For example, some members of a population of Bottlenose dolphins in Shark Bay off the west coast of Australia have been observed wrapping their beaks in sponges before hunting for fish near the seabed. This behaviour, called ‘sponging’ prevents the dolphins’ beaks from being injured by corals and sharp rocks while they forage.

Not dis-similarly, it was documented through the use of ‘secret’ filming for the BBC documentary Spy in the pod, that some bottlenose dolphins, particularly young males, enjoy deliberately administering themselves a non-lethal dose of pufferfish venom (read into that what you will!)

Of course, we are hesitant to over anthropomorphise these animals and to attribute human traits to their behaviours, but it’s hard not to with these animals who are so obviously intelligent, emotional and charismatic. As a child I wanted to grow up to be a dolphin, and to be honest, it doesn’t seem like too bad a life!

Au revoir, adios and good bye!

Hi everyone, welcome to the last installment of the Cap Finistère blog that will be written by myself, Katie. It is my final week on board and I am feeling very sad that I will have to say goodbye to the whales and dolphins of the Bay of Biscay as I have had a great time watching out for them and had an amazing three months! I’d like to thank both ORCA and Brittany Ferries for having me as it has been an absolute pleasure.

This week, Hazel and I felt as if we were welcomed on board by the ocean on Wednesday, as it delivered a beautiful sea state in the channel! We were therefore able to spot a Minke whale (YAY), which was my first one this season and only the second one we have seen on board the Cap Finistère this year. It is a shallow water species and has a very distinctive arched back and upright, curved dorsal fin when it surfaces, so we were able to identify it immediately and I was of course thrilled! We were also lucky enough to see some shy harbour porpoises swimming away and also a pod of Risso’s dolphins! This was another exciting sighting for me as it is only the second time I have seen them. Unfortunately what with all of the excitement these sighting caused, we weren’t able to catch any photos… Sorry!

The following day we saw some lovely common dolphins; these have become my favourite cetacean in the Bay of Biscay because they are so playful and we can always rely on them to show up and impress all of us!

We also had a sighting of a whale as we were right on top of the depth change area in the middle of the Bay of Biscay. Amazingly, we heard it exhale heavily when it first appeared which is what drew the attention of many passengers to it and we saw it exhale a second time which created a busy blow. My first instinct was that it was a beaked whale as it had a very rotund body and small dorsal fin, although we normally see them further south in the bay. Unfortunately I wasn’t quick enough with the camera so couldn’t get a photo, but if I were to hazard a guess I would say we saw a northern bottlenose whale!

Later on that afternoon we saw some more whales! I know, how great is that?! This time we could definitely identify them and they were none other than a trio of groovy Cuvies (which translates to three Cuvier’s beaked whales)! On the same deck watch we saw more pods of common dolphins and also a pod of striped dolphins too, so it was certainly turning out to be a great week!

On Saturday it was a beautiful sunny day but there was quite a rough sea state. Nevertheless the common dolphins didn’t disappoint, as in just the afternoon deck watch alone, we saw 56 of them; 4 of which were calves!

On Sunday I was on deck for my last sailing past Brittany and it was a beautiful sunny day so I got some brilliant views of the lighthouses and coastline. This area is also great for bird life and we saw cormorants, kittiwakes, Manx shearwaters many gulls and some young gannets that must have been less than a year old!

On Monday I had to say my final au revoirs to the French crew that disembarked for the crew change in Roscoff, which was sad as I have really enjoyed working alongside them! We did a deck watch in the afternoon which began in the northern part of the bay and although we didn’t see any cetaceans, we saw 12 blue sharks (yay for sharks) as it was yet another beautifully clear day!

This is one of the beautiful blue sharks that swam by the ship!

Later that evening, Hazel and I decided to go and see the sunset and we were also lucky enough to get a sighting of three beautiful pilot whales very close by in the evening light! It was stunning and neither of us could contain our excitement. Fortunately there were a number of passengers that witnessed them too and this certainly was one of my favourite sightings I have had all season!

On my final day we had another beautiful sea state and were lucky enough to see two separate beaked whale sightings! In our first deck watch we saw a group of 6 beaked whales, yes s.i.x.! That is the most I have ever seen together and although we are not 100% sure, we think they were northern bottlenose whales! Later on that day we also saw two more Cuvier’s beaked whales so I don’t know what is in the water at the moment but it certainly seems to be making the beaked whales appear!

Here is one of the 6 beaked whales we saw. We think it is a northern bottlenose, what do you think?

So it has been a very pleasant last week indeed, but I can’t go without talking about some more of the highlights of my time on board the Cap Finistère. First and foremost, there was the breaching fin whale which I saw in my second week. Yes, I’m sure everyone remembers that week; I for one will never forget seeing such a huge animal propel itself out of the water 5 times in a row. It was a beautiful sight to see and now a memory that I will treasure; it is amazing to think that we share our planet with such majestic creatures.

Here it is again, the breaching fin whale seen at the start of the season. An incredible sighting and one I will never forget.

I also have some other sightings that make it into my highlights: During week 9 I had a fabulous common dolphin sighting of a 40 strong pod which went on for about 5 minutes. One of the reasons I loved this particular sighting so much is because it was a beautiful sunny day, the water was crystal clear and the sea state was behaving! I was also lucky enough to see 2 Cuvier’s beaked whales together really close to the ship once, which we identified as a male and female and I am thrilled to have seen this because I am convinced they were in love!

CD10

Here is a final picture of a beautiful mother and dolphin calf from my favourite common dolphin sighting this season.

Finally I must mention one of the most important highlights of all, which was having the opportunity to work with my two fantastic colleagues, Jess and Hazel. These girls are both extremely knowledgeable about all kinds of wildlife and I feel as if I have learnt a lot from them. There has also been non-stop laughter, intriguing conversations and some great memories made. I wish them all the best in the future and I am very glad I had the opportunity to work with them! Thanks girls, you are both stars!

Thank you for reading. Au revoir, adios and good bye!

Whale Watching Works

Here’s your weekly update from myself, Andy, and Heather – your Wildlife Officers on the Brittany Ferries Flagship, the Pont-Aven!

Six days ago, as we crossed the northern continental shelf of the Bay of Biscay, Heather and I came across a group of more than half a dozen beautiful, jet black, long finned pilot whales.  They were travelling peacefully past the ship and were so unperturbed by our presence that they passed gently by, close enough for the many passengers on deck with us to enjoy some stunning views.  We were all elated and couldn’t believe our luck.  It seems that the captain and the bridge crew were also impressed as they quickly alerted the rest of the ship to the whales’ presence over the tannoy and people flocked to the rails to catch a glimpse of these magnificent animals.

Many hundreds of years ago in the twelfth century the Bay of Biscay was the scene of the world’s first commercial whale fishery, as Basque fishermen hunted down the North Atlantic right whales – or the ‘Biscayan whale’ as they were known at the time. They had soon exhausted the local population by the sixteenth century, and had started a process that would see that species become extinct in the north-east Atlantic long before the twentieth century.  The scene in Biscay is very different now.  Today ORCA wildlife officers like us showcase, to the travellers crossing Biscay, the wealth of fascinating wildlife that lives there. From this melonistic (a development of the dark-coloured pigment melanin in the skin and is the opposite of albinism) common dolphin

…to the apex predator, the sperm whale, which battles in the depths with huge squid the size of small whales – such as this one we came across floating on the surface beside the ship a week ago, passengers experience all that the Bay has to offer.

People are fascinated by all wildlife but particularly whales and dolphins and there seems to be some sort of inexplicable bond perceived by modern humans that draws us to these mammals.  Countless commentators and even scientists have attempted to quantify and explain it.  This wasn’t always the way and the extensive depletion of whale populations during commercial whaling is testament to that.  But the worst of those bloody times have passed and most societies around the world currently have a very different relationship with their cetaceans.  Attitudes to these creatures have changed across the globe; if only by recognising that a whale or dolphin is worth more alive than dead.  This is certainly the case for the booming whale and dolphin watching industry that has emerged around the world over the last 50 years.  No longer are whales perceived as a source of food or oil or fertiliser but their, more sustainable, worth to most states is now as a tourism resource.  Indeed the International Whaling Commission now recognises the importance of the industry and many member states would like to see it focus its attention on this sustainable use of these animals rather than the unsustainable hunting of the past.

In 2009 our friends at International Fund for Animal Welfare produced their ten year report on whale watching.  IFAW report This highlighted the rapid growth of the industry which had seen it almost double in the previous decade to a position where 13 million people a year were taking part in whale watching around the world and the industry generated over $2 billion in expenditures.

ORCA and Brittany Ferries have recognized this modern phenomenon with their Sea Safaris, which start in a couple of weeks, taking passengers across Biscay with the sole purpose of looking for whales and dolphins from the decks of the Pont Aven. It could even be argued that this is a particularly unobtrusive form of whale watching as the ferry is making the journey anyway and the animals are not pursued in any way.  These trips are extremely popular and the numbers taking part continue to rise just as the global whale watching community grows too.

But other than those beautiful pilot whales, what else have we been privileged to experience on the Pont-Aven this week?  Well the weather has been kind to us and summer really is here.  We have had calm conditions and each trip through the Bay has produced a number of Cuvier’s beaked whales.  In particular, the trio of one female with a young male and another scarred old white male in tow is still being seen.

Yesterday hundreds and hundreds of common and striped dolphins joined us for our outward and return journeys.  But perhaps our most memorable crossing later in the week was our Saturday evening cruise out of Cork where we spotted a fin whale before dinner and then returned to deck after 9pm, not far from the Cornish coast, to find the ocean like a mirror and manx shearwaters, common dolphins and five minke whales feeding around us in the fading light.

It was a magical hour that a number of passengers experienced on deck but by the time it was dark Heather and I were left alone with one equally enthusiastic passenger – a French masters student studying cetaceans at university in Galway and the three of us excitedly chatted about our common passion for whales as we squeezed every last drop of dolphin from the increasingly dark seas.

So sadly this is my last blog from the Pont-Aven.  In a fortnight, the Wildlife Officer season comes to an end on this ship and we all go our separate ways, each carrying a bundle full of images and memories that will stay with us for many years to come.  But soon the Sea Safari season starts and all of us will definitely be back to help as guides on those trips.  So we will be crossing the Bay of Biscay again looking for amazing sights and recognising the immense value that these animals bring to a world that is struggling to retain its wildlife jewels.

The Best UK Whale and Dolphin Spotting Spots!

Sightings update: This week I finally got my first glimpse of the resident bottlenose dolphins that live on the Brittany coastline between the Ile de Sein and island of Ouessant. This area is called The Iroise Sea, and in October 2007 is was designated as the first French Maritime Natural Park. It is always a real joy to sail through this area, and the regular presence of bottlenose dolphins, and many seals and seabirds, demonstrates how rich in biodiversity it is; this place is blossoming with life as a result of its protected status.

IMG_1139

The Bay of Biscay has been unbelievably quiet on the whale front this last week! I am hoping that soon the migrating fin whales will arrive to impress all our enthusiastic passengers. But for now the common dolphins are still holding the fort and keeping the public engaged and inspired! We also saw an unidentified dolphin which we only discovered later from our photos was actually a pilot whale! Sneaky!

A little trail of common dolphins

Many of our passengers have their first cetacean encounters on board with us and subsequently they are keen to seek out more marine wildlife experiences when they return home to Britain. So below I have put together some information on six of the best places in the UK for whale and dolphin watching:

  • Cardigan Bay

This is an extremely rich area for nature on the coast of Wales, which is home to bottlenose dolphins. The dolphins can even be seen from land as they come very close to the shore.

  • The Moray Firth, Aberdeen

This is certainly one of the best places to see bottlenose dolphins. There is a resident population in Inverness at Chanonry Point on the Black Isle.

  • West Coast of Scotland – Hebrides

My first ever encounter with cetaceans was in the Isle of Skye. I went on a boat trip that turned out to be a wildlife lover’s heaven! As well as spotting many seals and seabirds, including three white tailed sea eagles, a pod of seven gorgeous little harbour porpoises swam right past our boat. They were so close we could hear them puffing out the water from their blow holes. On that same trip we also saw a Minke whale and since then I have seen them many times on Skye from land. These experiences have been echoed in locations throughout the western islands of Scotland; friends have told me stories of whale and dolphin encounters from the Isle of Mull, the Shetland islands, the Isle of Rum and Isle of Coll.

  • Donna nook

Although ORCA is predominantly a cetacean focused charity, we do record all marine mammals we see on our surveys, including seals. I am a huge fan of seals and my interest in them began when I went to Donna Nook, a big stretch of coastline in Lincolnshire. Every autumn around three thousand grey seals haul out onto the beach to give birth to their pups and mate. It’s a brilliant way to get excellent close up views of seals without disturbing them.

  • Devon, Dorset, Cornwall, and the Scilly isles

Common dolphins are a regular site off the south west coast and pods of up to two hundred have been seen in the past on boat trips. Bottlenose dolphins are also present in this area as well as many grey and common seals. Devon had an unusual visitor this year; a humpback whale was spotted from the shore. Unfortunately this whale became entangled in lobster pot lines twice, but thankfully was rescued both times by the British Divers Marine Life Rescue (BDMLR). Lyme Bay in Dorset is home to a pod of white beaked dolphins, while the unusual Risso’s dolphin is often seen on crossings to the Scilly isles.  The ORCA surveys from Penzance to St. Mary are the second highest diversity route (after the Bay of Biscay of course!).

  • East Coast of Yorkshire

Places like Flamborough Head in Yorkshire are excellent for watching creatures like Minke whales from the shore. One of my favourite places in the world is Bempton Cliffs, just a few miles along the coast from Flamborugh, where there is a giant breeding colony of gannets. Here you can watch these huge birds bringing in fish for their young and you have the chance of spotting some cetaceans.

IMG_1029

These are just a handful of the UK sites where whale and dolphin watching is possible!

In your cetacean watching pack I would recommend packing:

  • Binoculars (ORCA sells some excellent binoculars in our online shop).
  • A Cetacean ID Book (I highly recommend Mark Carwardine’s Guide to Whale Watching in Britain and Europe, also available online here).
  • A notepad to record your sightings. We at ORCA would love to hear about what you’ve seen!
  • A camera to help you identify distant animals and capture magical moments!
  • Loads of food! I never leave the house to go wildlife watching without a full on picnic to keep me going!

Good luck on your whale watching adventures!

Jess, ORCA Wildlife Officer.

“I have a question..”

Hiya, it’s Sophie here, back from another week out at sea aboard the Pont-Aven.

In our role as Wildlife officers it’s our job to engage with the public and pass on our enthusiasm and knowledge. It’s a really great feeling to answer people’s curious questions about these charismatic but often enigmatic animals.

However, we can’t help but notice that there are a few questions that we get asked a lot more often than others. So I thought I’d share with you some of the most common we get asked, with some answers, in case you’ve been wondering some of these too. And if you board Brittany Ferries in the future you can impress us with your knowledge!

What time will the Dolphins arrive?  When is the best time to see Whales and Dolphins?

Now, despite being a Wildife Officer, wildlife does not take orders. There is no real predicting what time a cetacean may pop up and say hello. What we can say is that our likelihood of seeing whales and dolphins will depend on the time of year, and where we are on our crossing. So you don’t necessarily have to get up a dawn to have a great sighting, but of course, the longer you watch, the more likely you’ll spot something. So getting up early means making the most of the daylight.

The summer months of July-September are the peak times for cetacean watching in the Bay of Biscay and are when we run our Sea Safaris on board the Pont-Aven. However we have still had some great crossings earlier in the season as well, as you can tell from previous blogs! We also tend to get more activity when we are crossing the continental shelf and into the southern part of the Bay. An hour or so out of Santander is also a great area over the Torralavega and Santander Canyons. But really, you never know when you’re going to get a great sighting, something that makes whale watching so addictive!

IMG_9139

Beautiful sunrises, but they don’t guarantee sightings

Why do the dolphins come to the ship? Are all the whales going to be far away?

We often see common and striped dolphins swimming towards the ship, under and around it. And for the most part, this is purely out of curiosity and for fun. It makes great viewing and passengers can’t help but be charmed when they get a closer look. But a lot of people wonder why, and ask if the boat churns up water and fish. While we do sometimes spot dolphins feeding from the Pont-Aven, it is not as a result of the boat’s propeller, rather we just happen to be near shoals of prey that they are feeding on.

Dolphins will approach all sorts of vessels and it is well documented how they ride the bow wave at the front of a boat. This surfing enables them to move at considerable speed with minimum energy expenditure.  However, the Pont-Aven is just a bit too large that they can’t quite stay in the bow wave, and we move too fast for them to keep up indefinitely, so eventually we leave the pods of dolphins behind.  After the ferry has outpaced them we often see them jumping in the waves of the Pont-Aven’s wake.

Whales on the other hand do not come in to the boat in the same way many dolphins do. That doesn’t mean we don’t sometimes see them close, as we can do if we’re lucky. Whale blows can be seen nearly at the horizon, but we’ve often had the sneaky beakies, – the Cuvier’s beaked whales, pop up incredibly close to the ferry.

In the case of whales, it’s often that they come up to breathe wherever and whenever they need it…if it’s close to the ship or not!

How fast can they swim?

It does depend on the species, and there are conflicting reports and estimations. The top speed of cetaceans is normally only a speed they can maintain in short bursts, compared to a slower ‘cruising’ speed. Their torpedo like body shape is adapted to reduce locomotive drag as they move through the water. We often see the dolphins ‘porpoising’ through the water as well. This is a series of regular long jumps as they swim. This behaviour might look like a lot of effort, but it actually can conserve 30% of the energy they would have used if they were just swimming in the water. This is because there is less resistance during the time spent travelling than when the move through water.

The Sei whale is thought to be the fastest of the great whales with a top speed of 50 km/h. bottlenose dolphins can have a top speed of around 40-50 km/h but swim at around 10 km/h when not hunting or fleeing danger. With the common dolphins it is thought they can swim in excess of 25 km/h in a short burst. Of the small cetaceans, the Dall’s porpoise (native to the North Pacific) can swim the fastest at about 55km/h, almost as fast as a orca!

What is the whale blow? But in Finding Nemo…

All cetaceans will blow and exhale as they surface, however with the great whales, this creates a blow that can be seen from a considerable distance. Fin whale blows can be up to eight meters high and a blue whale can create twelve meter high blows! Unfortunately this answer has some ramifications for the accuracy of Finding Nemo. As the trachea and esophagus of whales are not connected, they cannot swallow water and then exhale it out their blowhole. The whale would have just swallowed Dory and Marlin whole and they’d have ended up in the stomach. The whale blows that we can spot from the deck are created when the whale exhales through the blowhole on the top of its head. The air inside the lungs is warm and moist, and this moisture condenses in contact with the cool air, forming the misty clouds we see. There’s also some mucus mixed in. After all, they are the nostrils of a whale.

How do Dolphins sleep? Do they sleep?

Cetaceans are what we call conscious breathers, this means breathing is something they have to think about, unlike humans. (But I bet you’re thinking about your breathing now). They have to consciously flex their muscles to open their blowhole, and when the muscle is relaxed, the blowhole is closed. This presents them with a problem if they want to rest, because if they need to actively breathe. Studies have shown that bottlenose dolphins engage in what we call unihemispheric sleep, where they are literally ‘half-asleep’. They can rest half their brain at a time, while letting the other half keep their body ticking over. Each side of the brain controls the opposite side of the body, so when the right hemisphere of the brain is resting the left eye will close, letting them sleep with one eye open. This enables them to rest without losing consciousness, as well as be vigilant for approaching dangers, and keep moving. They share this ability with certain bird species that must migrate over water.

What’s the difference between a porpoise and a dolphin?

Porpoises and dolphins are both in the order Odontoceti – the toothed cetaceans. However despite being closely related they are genetically distinct enough to be grouped into two different families – dolphinae (dolphins) and phocoenidae (porpoises).

This genetic distinction is evident in physical differences as well. Porpoises are generally smaller than dolphins with a more stout build compared to the dolphin’s longer body shape. Porpoises also have spade shaped teeth compared to conical teeth of dolphins. The dorsal fin of dolphins is a much more sickle shape than the equilateral triangle of the porpoises. And while they both have a rounded melon they porpoises lack the longer beak that most dolphins possess.

Can you recognise individual cetaceans here?

Yes, and no. It is much easier to determine individuals when you have a small well studied population that are resident to an area. Such as the bottlenose dolphins around Scotland, and the northern and southern resident groups of orca off the coast of Canada and the USA. This is usually based on variations in the dorsal fins, and building up photo catalogs of the individuals in an area. There are also catalogs of species when they have markings that differentiate them, such as using the mottled patterns of blue whales. However, in regards to the thousands of common dolphins that move through the bay, we cannot tell if it is the same pod we saw earlier in the week.

Well, that’s all for now. Heather and Andy are back on board the Pont-Aven for another week of whale watching. The weather is forecast to be quite good so here’s to them having a great week with lots of cetaceans!
