24 Jan 24 - ORCA Saga Caribbean Calypso Day 7 - An Unexpected Migrant Steals The Show

We were frustrating at first light on our first morning after leaving Tenerife to find that the visibility had dropped to only a couple of miles, from the fourteen miles to the horizon that we expected on perfect conditions. While it was possible to see more than a couple of miles, it wasn't easy and it would be very easy to miss Cetaceans surfacing beyond that distance. This was down to Saharan dust in the air. At dawn we were around two hundred miles South West of Tenerife & double that to the North African coast. The Saharan dust continued to be a problem causing hazy visibility for the next few days, albeit the visibility picked up to a few miles after that first morning.

Around mid-morning, I was off-duty on the starboard side when a shout went up from the port side. I hurried over to find a small pod of Atlantic Spotted Dolphins had popped up close to the side of the ship. Unfortunately, they stayed underwater as they enjoyed the bow wave on the port side of the ship: so my only views on this occasion were glimpsed through the water.

The undoubted highlight of the day came just before lunch when another port shout was heard for an Owl that was off the port stern side of the ship. I quickly got onto it as it started to circled the ship at height and shouted it was a Short-eared Owl. Well that wasn't on my prediction list for the trip. It circled the ship several times and seemed to be looking for somewhere to land, before we lost it from view at the back of the ship. By this point, our most recent thirty minute survey period was up & we decided to head down for lunch.
Short-eared Owl: The pale straw-brown patch in the outer primaries on the upperwing are a good sign this is a Short-eared Owl
Short-eared Owl: I love the bright golden eye colouration
Short-eared Owl: This is the nominate flammeus subspecies which occurs across Northern North America, Northern Europe to Northern Asia. The nearest breeding range is in the Spanish mountains to the East of Northern Portugal. They winter as far South as North Moroccan & Western Sahara and are a scarce to rare visitor to the Canaries
Short-eared Owl: Presumably, this individual was blown out to sea by the same winds blowing Saharan dust beyond the Canaries
Short-eared Owl: Note, the clean white underwings, albeit this individual appears whiter than others I've seen, and the broad black tips to the underwing primaries
Short-eared Owl: Note, the clean white lower body which would be browner in a Long-eared Owl

I had a good look around the upper decks for the Short-eared Owl as it quietened down on deck when the restaurants opened for dinner that evening. This was followed by another early look around the decks on the following morning. There were no subsequent sightings over the following days and we concluded that the Short-eared Owl hadn't landed on the ship. Unfortunately, there were a lot of people on the upper decks when the Short-eared Owl was seen, as the weather was warm enough for sunbathing, and it clearly hadn't felt comfortable landing on the ship. This saved the worry of whether it would be possible to provide it with any food given we were to be at sea for six days. We did see a Baja Ferry heading towards the Canaries when we returned from lunch. If it saw that ferry, which didn't have open top decks, it might have been able to get a ride and been in the Canaries the following day. If not, sadly the chances of it finding land were bleak, given the Canaries were the nearest land and that was two hundred and fifty miles North East of us.

Here is a comparison photo of a Long-eared Owl, taken in Turkey in Summer 2015.

We discovered a few stowaways on the ship during the day. Firstly, a Canary Red Admiral flew around the upper deck a couple of times without landing. This is a brighter marked species than our Red Admiral and it has less extensive white in the wing tips. A large Dragonfly passed along the deck at least twice: a Vagrant Emperor or Lesser Emperor would seem to be the most likely option. I had thought it was a Hawker at the time, but there aren't any Hawker species on the Canaries. The best stowaway was a Striped Hawk Moth that we also saw on a few occasions over the first two days at sea. I only saw it briefly land once and unfortunately, it was on a sunbathing passenger: so I decided that was not the right opportunity to try & take a photo. The Saharan dust had made the day more frustrating on our first day at sea after Tenerife. But the appearance of the Short-eared Owl, the stowaway insects and the brief views of the Atlantic Spotted Dolphins had made it a good day.

The Saharan dust continued into our second day at sea after Tenerife. I had a distant sighting of a Band-rumped Storm-petrel. There are now three species of Band-rumped Storm-petrel breeding in the North Atlantic, and it wasn't possible to resolve this to a specific species. A second Storm-petrel sighting was even briefer and that remained as a Storm-petrel sp. A Cory's Shearwater, more views of the stowaway Striped Hawk Moth & our first two Flying Fish completed the wildlife list for the day.
The Wildlife List at the end of the second day: Despite the limited number of sightings, we still persevered with our dawn to dusk deck watches, barring meal breaks
That evening saw the first of the formal evening dinners. On the weekly formal nights many of the passengers dress up in dinner jackets and fancy dresses. This was expected clothing for the speciality restaurants on the formal nights, but a suit and tie were OK in the normal restaurant, which was a positive for me as I have no interest in ever wearing a dinner jacket. As the ORCA team were considered part of the entertainment team, we were not allowed in the speciality restaurants, even if we were invited by a passenger.
The first of the formal dinner evenings: I always wore a jacket to dinner, but I added the optional tie for the evening
The food was superb and and it always looked fantastic
After the meal, we bumped into Penny and Terry as they came out of one of the posh restaurants
It was great to see that the ship were advertising our deck watches

4 May 18 - West African Pelagic - Day Four: Gervais's Beaked Whales Off The Canary Islands

As we cruised along the deep water channel between the Canary Islands, we had views of El Hierro & La Plama to our port & La Gomera & Tenerife to our starboard. The morning had got off to a good start with some Bryde's Whales & Short-finned Pilot Whales as an aperitif to breakfast. Additionally, there were good numbers of Cory's Shearwaters & a few other Seabirds, compared to the previous couple of days when we had been travelling through the deep oceans. The rest of the morning had been quiet for Cetaceans. Finally, in the early afternoon, my time on deck was rewarded when a pod of Striped Dolphins raced past going the other way.

During the afternoon, Bob Flood was lined up to give a talk on Pterodrama Petrel identification in the North Atlantic. It was a difficult decision about staying on deck given there was a fair bit of activity or attend what would have been an excellent talk. Had the talk been while we were in the deep oceans, then I would have attended the talk. But given we were close to steeply sloping seabed & land, I decided to stay on deck. Fortunately, the Cetaceans kept up the interest. Firstly, there was another pod of at least thirty Atlantic Spotted Dolphins.

Finally, in late afternoon, there was a shout for a Beaked Whale close to the bows on the starboard side. I was on the port bridge wing, but had the opportunity to get some photos before it started to move down the starboard side.
Gervais's Beaked Whale: With many of the Beaked Whales it is important to see the head & beak shape so to see that on the first photos is good news
Gervais's Beaked Whale: A close crop of the head. This confirms that the jaw shape does not turn up, which rules out Blainville's Beaked Whale & True's Beaked Whale. Sowerby's Beaked Whale can be ruled out as they have a longer, thinner beak & a more prominent bulge on the forehead. Cuvier's Beaked Whale have a really stubby beak & the colouration is also wrong for this species. Finally, Northern Bottlenose Whales have a completely different beak & head shape. This just leaves Gervais' Beaked Whale as the last option in range & fortunately, the head, beak & jaw shape all fit for Gervais's Beaked Whales

Gervais's Beaked Whale: Going down & more importantly I'm running out of opportunity to lean right from the port bridge wing & photograph it. Time to move as fast as possible to the starboard side
Many of the least known Cetaceans are Beaked Whales. They do not have obvious blows like the large Whales, do not linger on the surface for long periods of time like the Pilot Whales or regularly jump of out the water like the Dolphins. Additionally, many are a dull grey or brown & do not stand out, especially when the light makes the seas look grey. A number of the Beaked Whales species are thought to dive deep to hunt Squid & so they will spend a fair bit of time underwater. Finally, with the exception of three Northern Bottlenose Whales that I've seen from land, all the Beaked Whales that I've seen have moved straight past the ships I've been on, without taking any interest in the ships. With this air of mystery, then they are generally the group of Cetaceans I want to see the most.
Gervais's Beaked Whale: I reached the starboard side to find one was very close. But it would be very hard to identify it as it wasn't possible to see much on the head or dorsal fin

Gervais's Beaked Whale: Another photo of the same two individuals
Gervais's Beaked Whale: The third Gervais's Beaked Whale appeared (in the bottom right). The other two are top left, albeit one had already slipped below the water
It was the start of Happy Hour in the Observation lounge & a number of people were below decks when the Gervais's Beaked Whales came through. However, they had a second chance a couple of hours later when there was another Gervais Beaked Whale sighting.
Gervais's Beaked Whale: Other people's photos also confirmed this was a Gervais's Beaked Whale, although my photos don't. It clearly has an odd dorsal fin shape

In early evening, there was final Atlantic Spotted Dolphin pod that briefly appeared by the Plancius, to put on a final show for those still on deck.
Atlantic Spotted Dolphin: Sub adult. This was the only individual I managed to photograph in this pod
Atlantic Spotted Dolphin: Sub adult. The white tip to the beak & the grey & pale markings indicates this is a sub adult Atlantic Spotted Dolphin. Note, most of the pale spots are probably water droplets rather than markings
I had spent another twelve hours or so on deck, but it had been rewarding.
