Heysham-Dublin survey 8 August

Nuala and I arrived at Heysham from Blackpool and St Bees respectively shortly before midnight. The transfer to the Seatruck Pace was very efficient and, following a quick discussion about the survey ahead, we were able to get some sleep before an early start the following morning.


Breakfast was at 6.30 and before we were able to survey in earnest, we kept an eye out for wildlife from the passenger lounge windows. Although it was generally quiet, a Storm Petrel fluttered past which was a good sign for the rest of the day.

We joined the bridge at 7.05 and were able to survey until 9.30 when the ship entered the harbour at Dublin. On the crossing we saw a variety of the expected seabirds, including Fulmar, Gannet, Kittiwake, and Manx Shearwater. We were heartened to see plenty of Guillemot and Razorbill, including some young despite the avian flu issues in the Irish Sea. The Storm Petrel tally also advanced with a group of four birds and a single added to the one seen earlier.


Cetacean observations were also good in what is usually one of the best months of the year on this route. Beginning with a small group of Common Dolphin we also saw several Harbour Porpoise, but to crown a good couple of hours we had no fewer than four Minke Whale apparently feeding together ahead of the ship!

After we stopped surveying on entering the harbour, we saw a few birds not recorded during the survey itself. As well as a single Black Guillemot there were several Mute Swan. We scanned through the large gatherings of gulls around an outfall to try and pick out a Mediterranean Gull but drew a blank. We were treated to a filling lunch and also made a head start on some of the paperwork whilst docked.


When we returned to the bridge for the return leg at the agreed time the vessel was already outside the harbour, and we began the survey, initially distracted by the tender boats taking passengers to and from the Silver Moon cruise liner moored in south Dublin Bay!


There were again good numbers of auks, gulls, and Manx Shearwater as we headed east, while several more Harbour Porpoise were seen, including one small calf. A pod of Common Dolphin, though never close to the ship, was certainly very active and offered the best views of the survey. A pale-morph Arctic Skua passed close in front of the ship as it headed north, and the tally of Storm Petrel continued to tick over to give an exceptional total for this survey route. We did sadly see a small number of dead Guillemot which was expected given the large bird flu outbreak in the Irish Sea, but still sobering.

As we passed the Isle of Man sightings quietened off as they often do on this survey. We were, however, treated to some stunning skyscapes as the sun set, and a grandstand view of the iconic tower and the ‘Big One’ ride in my hometown of Blackpool before dusk, and afterwards in the case of the then illuminated tower.


All in all, it was an excellent survey in great conditions, and we are hugely indebted to Captain Suharevs and the crew of the Seatruck Pace who as ever were so very welcoming to us.
