Saturday 22nd April 2017
Steve and I had arrived at Seaforth Docks, Liverpool Friday evening and at 22.00 hours our passports were checked and then we were taken by shuttlebus to J.R. Shippings M.V. Endeavor where we were made very welcome by Captain Vitaly Shutov and his officers. We were then taken to our comfortable cabins for a good night's sleep. The following morning after an enjoyable breakfast we were given a safety tour and briefing of this impressive container ship by the 1st officer. This was to be a particularly interesting survey for us as the ship was sailing to Greenock and then on to Bilbao rather than the usual Dublin to Bilbao route, a total distance of 2,700kms.
Endeavor (Graham Ekins)
The ship left the dock early evening and we were able to start recording once the Pilot had left the ship. During this time we had an opportunity to view from the deck a huge flock of Knot twisting and turning over the Mersey Estuary with the Blackpool tower as a back drop. We also had brief views of Harbour Porpoise and large flocks of Oystercatchers and Grey Plovers on the Formby Point beach. Once on the bridge we logged a flock of 50 Common Scoter heading purposely northward as well as our first Puffin, Gannet and Manx Shearwater.
Sunday 23rd April 2017
The following morning dawned bright with a light NW wind and great visibility. We were heading north towards Greenock and were sailing past the superb island of Ailsa Craig to the east then the Isle of Arran to the North-west. We then past the islands of Bute and Great Cumbrae, it was truly a stunning route with such superb scenery. We recorded both Bottlenose Dolphin and several Harbour Porpoise as we headed into Firth of Clyde as well as a Nuclear Submarine out on exercise. The sheer numbers of Manx Shearwater was staggering with many hundreds logged as we headed north as well as many Gannet, Kittiwake and Guillemot presumably from the large colonies on Ailsa Crag. As we headed further north in the Firth of Clyde we encountered our first Eider, Shag and Red-breasted Merganser. We were also delighted to get more sightings of Bottlenose Dolphin and Harbour Porpoise in almost calm conditions. As we docked we could see several Black Guillemot by the Pilot House. Captain Vitaly Shutov gave us permission to leave the ship and so we took the opportunity to walk around to nearby Campbell Street where the Black Guillemot were nesting in the old sea wall.
Black Guillemot (Graham Ekins)
On returning to the ship we entered the first of the data. We then started recording again late afternoon as we headed south. This time there were many sailing boats out in the superb conditions and we did not record any more Cetaceans. The seabirds were however just as numerous with 1400 Manx Shearwater, 180 Guillemots and Gannet logged by dusk. We then left the bridge for an enjoyable cup of tea before heading for bed.
Monday 24th April 2017
This morning we awoke to light westerly winds in the Celtic Sea as we headed steadily south. Initially it was thick cloud but as the morning progressed this thinned and the day became much brighter. We immediately started recording Manx Shearwaters crossing our bows heading west in increasing numbers the further south we went. We presumed these were out foraging from colonies on Grassholm and Skokholm off the Welsh coast. We were also seeing many summer plumaged Guillemot and the occasional Razorbill following the same path. At 08.00 Steve picked up an adult Pomarine Skua moving steadily North, this proved to be the only one on this survey. This was quickly followed by our first of many pods of Short-beaked Common Dolphin coming in to bow-ride on the Endeavor. From mid-morning we started to see Puffin flying west or sitting on the sea, presumably from nearby Welsh colonies. We also started to see increasing numbers of adult Lesser Black-backed Gull and the occasional Kittiwake. By mid-day we were in the southern Celtic Sea and found several large flocks of roosting Manx Shearwater, these presumably were waiting for dusk before flying to their breeding colonies. By late afternoon we were between Lands End and the Isles of Scilly, the numbers of Manx Shearwater had decreased but we were seeing more Guillemot and increasing numbers of adult Great Black-backed Gull, presumably breeders from the Isles of Scilly. It was then that we saw a close Bottlenose Dolphin, the only one seen that day. As we continued south towards the Brittany Peninsular the numbers of birds decreased steadily, the exception being the sighting of several Great Skua, often flying in the direction of distant fishing boats surrounded by hundreds of Lesser Black-backed Gull, Gannet and Kittiwake. As the light began to fade we left the bridge but not before seeing a beautiful sunset over an almost calm sea.
Tuesday 25th April 2017
We had an excellent overnight sleep as the winds were fairly light. The almost flat calm conditions and beautiful sun set of the previous evening had been replaced by thick cloud, luckily the winds were still only force 3. We had expected it to be from the NW but it was blowing from the east and this continued all day. We were now in Central Biscay, initially we had the occasional patch of drizzle but before long the rain became constant but luckily only the occasional heavy burst and the visibility remained good. Within a few minutes of getting on to the bridge we had spotted a blow from a Fin Whale on the Starboard side as it dived. At the time I had been watching a group of 50 Arctic Tern roosting on the sea, something I had only seen previously in the South Atlantic. A few minutes later 2 more Fin Whale showed well on the port side before diving out of sight.
Fin Whale (Graham Ekins)
Almost as soon as the rain started just after 07.30 the first passerines dropped on to the boat and during the first hour we logged several Willow Warbler, Woodlark and most unexpected a Quail that came rocketing in and dived under one of the containers. Seabirds included our first Yellow-legged and a few Lesser Black-backed Gull.
Then the first of several Whimbrel flew in and landed on the
containers. Initially they just stood with wings drooping
suggesting that they had flown a long way but after an hour they
looked more alert and later they took off and joined a passing
flock. We then had another great Fin Whale sighting with 3 showing
well on the port side. We managed to get images of this group. Two
hours later three more were seen well before they disappeared below
the waves, this brought the total to eight for the morning.
We had been travelling down the 2,000 metre deep St Nazaire Canyon
and this was clearly a popular location for these large
As the morning progressed we continued to have birds drop on to the boat, this included a totally unexpected Sardinian Warbler which showed briefly on deck before diving amongst the containers, we also found a grey continental Song Thrush and a Sedge Warbler while 2 Swallow and 2 Sand Martin battled their way east. The Cetacean activity continued with 4 Risso's Dolphin showing off on the starboard side quickly followed by our first bow-riding Short-beaked Common Dolphin. Over the next few hours we had several hundred Short-beaked Common Dolphin approach the boat to bow-ride, this included a pod of 300 that we estimated had about 50 youngsters with them.
Whimbrel (Graham Ekins)
Then mid-afternoon we spotted a group of Yellow-legged and
Lesser Black-backed Gull circling over a pod of Cetaceans, they
prove to be 10 Striped Dolphin and the first of the survey. During
the afternoon yet more birds appeared on deck, this included Yellow
Wagtail, Goldfinch, Common and Black Redstart, Chiffchaff,
Whitethroat, Blackcap, Lesser Whitethroat and a Grasshopper
While many flocks of Meadow Pipit and 2 Tree Pipit passed east and 5 Linnet flew over heading North. Then as another rain shower started a superb male Greenland Wheatear dropped out of the sky along with a near summer plumage Turnstone and a Female Kestrel. Another Turnstone then made a brief appearance and a Dunlin flew around the ship before heading east. Into the evening pods of Short-beaked Common Dolphin continued to appear and bow ride, then Steve picked up a large pod of Bottlenose Dolphin that did the same. We counted 35 with both adults and young present. As we approached Bilbao towards dusk it was gratifying to see many of birds that had arrived during day lifting off and heading towards the Spanish coast.
Whitethroat (Graham Ekins)
Several birds had found the large number of Silver Y moths that were on board an excellent food source. Even the tiny Willow Warbler and Chiffchaff were eating them. This was one of the most memorable MARINElife survey days that either of us had experienced.
Wednesday 26th April 2017
We were moored overnight in the new harbour at Bilbao and awoke to heavy rain and a forecast that suggested this would continue into the afternoon. After breakfast and during a short interlude we scanned the nearby hillside and saw the local Red Kite, Raven and Spotless Starling. It then started to rain heavily again and so we abandoned our plans to get a taxi to the summit and walk down through the small fields, allotments and woodland. Instead we concentrated on entering the data from the previous few days. This was great as it would save me a lot of time on getting home. By mid-afternoon the rain had eased and the sun started to come out. With the warmth the first Black Kite started to soar with the local Yellow-legged Gull over the nearby hills as did White Stork and Raven. In the nearest fields were more Spotless Starling as well as Iberian Stonechat and a White Wagtail. A few hirundine started to move including a flock of Swallow flying low north over the harbour. Over dinner we said goodbye to Captain Vitaly Shutov, he and his officers had made us very welcome since we left Liverpool. He was going home for a well-earned break. Towards dusk the loading of the containers was completed the pilot came aboard and the Endeavour left the port for its trip back to Liverpool.
Thursday 27th April 2017
The morning dawn dull with rain showers and a cool NW wind. We met Captain Vladimir Gornev who had arrived on board, he had arrived the previous evening and was very interested in our MARINElife sightings. It proved to be a very busy day with superb views of several of the 8 Fin Whale, 4 Risso's and 17 Striped Dolphin. We also logged 20 Bottlenose and 537 Short-beaked Common Dolphin. The seabirds were quite scarce for the early part of day but as we headed north Manx Shearwater became more common as did Gannet and Kittiwake. We also had a few summer plumage Puffin.
Bottlenose Dolphin (Graham Ekins)
Waders were very much in evidence during the afternoon with flocks of 15 summer plumaged Knot and Grey Plover and 6 Whimbrel all heading NE. We also had 2 Storm Petrel which could have been from the Spanish breeding population. This was another varied and enjoyable day.
Friday 28th April 2017
Steve and I arrived on the bridge just as it was getting
light. The sky was overcast but the winds were just a light
NW. As the morning progressed the cloud started to thin, all day
the visibility was excellent. At 06.00 the Endeavor had
passed north between Lands End and the Scilly isles, we were now in
the southern edge of the Celtic Sea and soon to enter the area of
the Celtic Deep with 90+ metres of water. We started to log Gannet
heading out west, presumably from the large colony on Grassholm to
the NE. We also had many Manx Shearwater travelling in the same
direction. A phenomenon observed the southward leg of the
survey. With such light winds we were able to pick up small
pods of Short-beaked Common Dolphin in groups of up to 20.
One group near the ship was so busy hunting for fish in a tight group that it totally ignored the Endeavor. It was also pleasing to see that most of the pods contained adults and young. The westerly movement of Gannet and Manx Shearwater continued most of the morning with the occasional Fulmar, Guillemot and a few summer plumaged Puffin.
Common Dolphin (Graham Ekins)
In the afternoon the numbers of Puffin steadily increased with groups as large as 12 being recorded. Late morning a flock of 5 Whimbrel overtook the ship heading NNE while several Great Skua rapidly overtook the ship also heading north. We also had our only Harbour Porpoise of the day when 2 were spotted only 250 metres from the ship. As we steadily headed north the temperature started to rise and for the first time on this survey the winds went around to the south-west. By now the numbers of birds recorded had slowly decreased but we did start seeing summer plumaged Razorbill, they had until now been a scarce bird. We continued to record the occasional Manx Shearwater, Puffin and Gannet as we headed towards Anglesey. The visibility was so clear that we could see the Isle of Man 70kms to the north. At dusk we packed away our equipment for the last time and thanked Captain Vladimir Gornev for the way he and his officers and crew had made us so welcome on the M.V. Endeavor on the northward journey. We also thanked Oscar the chef who has supplied us with such excellent meals.
We arrived in Liverpool in the early hours of Saturday morning. After an enjoyable breakfast we left the ship for the long journey home. It had been an incredibly successful survey with 1,547 Cetaceans and 5,100 birds logged.
Our thanks to Captains Vitaly Shutov (southbound), Vladimir Gornev (northbound) and the officers and crew as well as to J.R. Shipping for supporting this important survey route.
