14 Feb 24 - ORCA Saga Caribbean Calypso Day 28 - A Valentine's Day Bryde

Day five at sea from the Caribbean to Spain on the Saga Caribbean Calypso was uneventful for me. Fortunately, the seas had returned to the normal four metre swells after the rougher seas of the previous late afternoon. It seems a lot of swell, but the Spirit of Discovery wasn't uncomfortable in that swell. But as we headed East, and a bit further North, the daily temperature dropped each day. We were still doing our all day dawn to dusk surveys, with the only breaks being for breakfast and lunch. A few Cory's Shearwaters provided my only Avian interest during the day. Additionally, Charlotte & I saw a lunge feeding Whale pass down the port side: the identification wasn't clinched, but it was probably a Humpback Whale. Unfortunately, the views weren't sufficient to identify it and as nobody managed to get any photos, it had to be logged as an unidentified Whale. That's the problem when the seas have a strong swell, even large Whales at a distance can be lost in the waves. A lone Smurf was the nearest I got to any Flying Fish all day.
This dead Moth sp. was found today on the deck: Presumably it's a Caribbean species
We were back on deck at dawn to start our surveying on day six at sea from the Caribbean to Spain on the Saga Caribbean Calypso. As always we were hoping for some Birds and Cetaceans. The Birds picked up and I saw eleven Cory's Shearwaters. Not many, but better than the half a dozen from the previous day. The Cetacean highlight was a Fin Whale, with a second set of nearby blows.
Cory's Shearwater: The lack of white on P10 makes this a Cory's rather than a Scopoli's
Cory's Shearwater: The same individual
In the afternoon, Terry and I held the first of two Wildlife Clinics in one of the lounges. This was the opportunity for the passengers to come and have a chat about anything on a Cetacean, Bird or other Wildlife theme that they had encountered during the trip. Both sessions were well attended and we managed to identify most of the photos that the passengers brought along. Jan and Charlotte stayed surveying in our absence and they were joined by a new helper, called Big Blue, who was press-ganged into joining the ORCA team on deck. His appearance also attracted a couple of Short-beaked Common Dolphins and two more unidentified Cetaceans, unfortunately, while Terry & I were running the Wildlife Clinic.
Charlotte bought Big Blue in the Caribbean to add to her ever growing menagerie in the cabin

Big Blue with Monica, who was another of our regular visitors: He ended up getting a lot of attention, especially from the female passengers when he appeared on deck. His appearances helped to provide a bit more fun on deck when it was quiet
The end of the day noticeboard: It had been a better day that my notes suggested
Day seven at sea from the Caribbean to Spain on the Saga Caribbean Calypso, was similar to the previous day. There was a bit more variety on our last full day at sea, before we reached the Spanish coast and the lovely city of La Coruna. I only saw one Cory's Shearwater all day, but two Gannets and fifty-eight Kittiwakes brought a more European feel to the day. Six distant Terns and twelve medium-sized Waders were interesting signs of migration well out to sea. I didn't see any Cetaceans, but I did have a Shark sp. swim down the starboard side of the ship. Terry & I ran a second Wildlife Clinic in the late afternoon.

Day eight at sea from the Caribbean to Spain on the Saga Caribbean Calypso, had a different start as we were relatively close to the Spanish coast & heading for La Coruna on the North West coast. We were hoping for some early morning Dolphins, given we were close in shore. But our main hope was the Bryde's Whale that Charlotte had seen the previous Autumn. She had been in touch with a local Whale-watching company and had heard that it was still around in the bay. As we got closer to La Coruna's bay, we could see lots of Gannets ahead and plunge-diving into the sea. Clearly, there were fish in the area. We picked up a pod of about twenty-five Short-billed Common Dolphins, then Charlotte shouted she had just see a large Whale surface amongst the Dolphins. We needed to get some photos to confirm its identification.
La Coruna Bay
Bryde's Whale: It was still distant, but we could see it was a large Whale
Bryde's Whale: A size comparison with one of the Short-beaked Common Dolphins to its right. It was a large Whale, but it didn't had the length or bulk of a Fin Whale. We needed to get some better photos
Within a couple of minutes, the Bryde's Whale was on view again. They have three prominent ridges on the rostrum, while similar species generally have a single ridge. The head is about twenty-five percent of the body length. The dorsal fin is tall, rises steeply, falcate, generally pointed at the tip and is often notched on the trailing edge. Males can be up to fifteen metres, with females about ten percent longer.
Bryde's Whale: While it is a large Whale, it hasn't got the bulk and length of a Fin Whale
Bryde's Whale: A harsh crop of the last photo. It has a pronounced broad-based dorsal fin with a smooth curve on leading edge, a pointed tip to the dorsal and it just appears to have a notch near the top of the back of the fin
Bryde's Whale: Fin Whales also have this smooth curve on the leading edge of the dorsal fin which rises at a shallower angle. Sei Whales have slender tall dorsal fin, with a distinctive kink halfway along the leading edge
Bryde's Whale: Sadly, the three ridges aren't a lot of use if you can't see the head
The title of this Blog Post suggests a romantic theme. But in reality, Bryde's Whale is named after the 19th Century Norwegian whaler, John Bryde, who was set up the first whaling stations in South Africa His name is pronounced and Bryde’s whale is pronounced as "BROO-dus".
Bryde's Whale: Based upon the dorsal fin shape and size, this looks good for the Bryde's Whale that had been hanging around La Coruna for the previous few months
Bryde's Whale: A harsh crop of the last photo. It has a pronounced dorsal fin with a smooth curve on leading edge, a pointed tip to the dorsal and a clear notch near the top of the back of the fin
La Coruna looked at interesting city with the Tower of Hercules Lighthouse and an interesting surrounding park containing a number of art statues.
The Tower of Hercules Lighthouse: The original Roman Lighthouse dates to the 1st Century. In 1788, the original Roman Lighthouse was protected by a new stone outer tower

Horn anybody?
As always, we needed a pilot for the final entry into the port
The harbour wall breakwater: There was a light display on the green semi-circular arch
The Castelo de Santo Anton dates to the 16th Century
We stayed on deck looking to see what Birds we could see as we came into the port. This included fifteen Cormorants, a number of typical Gull species roosting on harbour docks and a Peregrine chasing Feral Pigeons over the town.
Cormorant: This is the continental sinensis subspecies which occurs from North & central Europe to South China. They winter as far South as South East Asia & Indonesia, as well as, being a common wintering species in the UK, alongside our native carbo subspecies

La Coruna has these interesting glazed window balconies, called galerias: They were designed by naval architects for rainy days. Very soon, it became a popular style for town houses across this corner of Spain

To make up for the failure to get to the Azores, the passengers were going to have a day & a half in La Coruna. I'm sure some took the opportunity for a meal ashore on Valentine's Day.

13 Jun 22 - The Isle Of Purbeck Pelagic

Back in June 22, I was lucky to be invited by my friend Mark Singleton, who is one of the local National Trust team, to join one of the annual breeding Seabird surveys that are carried out by Footprint Ecology for the National Trust. The survey covers the Purbeck coast from Durlston to St Aldhelms and along the cliffs to Old Harry. We left Swanage on one of the small fishing boats and sailed past Durlston as far as St Aldhelms, before returning along the same coastline. The only problem with the trip, we were warned we would be out from 09:00 to early afternoon, which turned into mid-afternoon & there wasn't a toilet on the boat. Therefore, it was a case of skipping breakfast and limiting myself to a single cup of tea for breakfast.
Durlston Castle: Durlston Castle is a Victorian folly & restaurant that was built in the four years before its completion in 1891 by George Burt. Burt made his fortune running the family firm, Mowlem, who mined and shipped Purbeck stone to London. The Castle was the centrepiece of his Durlston Park. It is now owned and run by Dorset County Council as the centre for Durlston and the start of the Jurassic Coast World Heritage Coastline
The Tilly Whim Quarry at Durlston: This old quarry area is now closed off as the underground quarry works are in a dangerous state
My Durlston Seawatching location: This is where the lighthouse gully reaches the sea and it provides the lowest point for seawatching at Durlston. There is a similar low point at St Aldhelms: but it is a mile & a half walk from the car park to the start of the steep track to the base of the cliffs which includes a short climb up & down one part of the path

Looking West from Durlston
Durlston Climbers: There is a part of the Durlston Country Park where climbing is allowed which is well away from the Seabird ledges

As we passed the Durlston cliffs, we started to see the first of the Seabirds. Durlston has the highest densities of Seabirds on the Purbeck coastline. The vast majority of the Auks are Guillemots, with a small percentage of Razorbills. There are some breeding Fulmars, Shags, Herring Gulls and a few pairs of Kittiwakes. The Purbeck speciality is easily the handful of pairs of Puffins in the Dancing ledge area.
Fulmars
Guillemots: There are good numbers of Guillemots on the Durlston undercliffs
Debbie & Durwyn surveying one of the Guillemot ledges: The counts are supplemented with photos of all the cliffs, so that the field counts can be confirmed from examination of photos. These photos will provide additional information for comparing results from one year to another

Bridled Guillemot: The bird of the day was this Bridled Guillemot. This is a colour morph which increases going North in the Guillemot range. They are scarce in Dorset, but commoner in the Shetland Islands. It is the first I've definitely seen in Dorset
Razorbills & Guillemots: This photo is good at showing the black Razorbills from the browner Guillemots

Blacker's Hole: This is one of the sea caves at Blacker’s Hole & it is home to the last small colony of Purbeck Kittiwakes: we saw six occupied nests

Herring Gull: This Herring Gull looks like it is still incubating
Herring Gull: This Herring Gull nest has two healthy-looking chicks
Peregrine: This is one of the Durlston Peregrines
Little Egret: One or two of the Poole Harbour Little Egrets feed along the Purbeck coastline
Dancing Ledge: This is another ex-quarrying area which is now part of the National Trust coastline to the South of Langton Matravers
Dancing Ledge: As we passed Dancing Ledge, this group of school kids were preparing for a coastal activity of some sort. Good to see they were all wearing safety gear & wetsuits
The Dancing Ledge area and the Portland West Cliffs are the only known parts of the Dorset coastline where Puffins still attempt to breed. There are no more than a few pairs in the Dancing Ledge area. I don't think anybody has been able to confirm successful breeding for a number of years. However, I doubt there are many people actually looking along this part of the Dorset coastline when they would fledge. Therefore, are the pairs failing, perhaps as the nest sites could be accessible to a land predator or are they sometimes successful & Birders aren't looking for Pufflings.
Puffin: The Dancing Ledge area is the only known part of the Purbeck coastline where Puffins still attempt to breed
Puffin: It's great having this gorgeous species so close to home
Swift nest hole: There is a small Swift colony on the Purbeck coast near to Dancing Ledge. This is one of a few cliff-nesting Swift colonies in the UK. A Swift had just flown into the nest hole
Sika Deer: This was the surprise of the day. It's hard to see how this Sika Deer reached this platform
Sika Deer: It looks quite content when this photo was taken. They are a semi-aquatic species of Deer, so it is possible it could jump in the water & swim along the coast to a beach where it could get out of & back onto the downs
Finally, we reached the Winspit to St Aldhelms section. There is another reasonable sized Guillemot & Razorbill colony on this section, along with a few Fulmar nests. As we reached the St Aldhelms tide race, the sea got a bit more bouncy, but we were soon past the last of the breeding Seabirds and turning around.

Approaching St Aldhelms: It was time to turn around and enjoy the trip back to Swanage, as the survey was over
Peveril Point: This is the last point of the Jurassic Coast, before the turning into Swanage Bay. Mark is relaxing & chatting with Durwyn & the team
Sea Kayakers: These two Sea Kayakers were enjoying the seas off Peveril Point
We weren't done yet as we crossed Swanage Bay to cover the chalk cliffs of Ballard Down as far as the breeding Gull colony on Old Harry. But I will cover that in the next Blog Post.
