The ships departure was later than scheduled due to tides, so I took the scenic route from home in Blackpool through the villages of Over Wyre.  There was a large flock of Pink-footed Geese at Pilling, and I picked out a Tundra Bean Goose among them to get the day off to a good start.

We arrived at Heysham terminal in good time and having booked in, made our way across to the Clipper Ranger, retired to our cabins for some sleep before an early morning start.

Arctic Skua Graham Ekins 01Unfortunately when he went up to the bridge at dawn we were met with thick fog which persisted for some time.  Eventually it did begin to lift, and when it did, highlights of the outward leg included a dark phase Arctic Skua harrying a juvenile Kittiwake and three separate Harbour Porpoise sightings including an adult and calf.

Although no passerine migrants were grounded on the vessel, during the fog we did see a couple of Swallow battling south over the waves after it cleared.  As we approached the port of Dublin several Mediterranean Gull were appreciated if largely expected these days, whilst all the ferries were dwarfed by a large cruise liner arriving for the day.

Fulmar Peter Howlett 17Our return crossing began with much better visibility, but there was a fair breeze up initially and we didn't see any cetaceans throughout the return leg. We were however privileged to see three separate Storm Petrel pattering across the water among other seabirds.  The fifth Arctic Skua of the trip was the first pale morph we had seen, and there were good numbers of Fulmar as well with over 300 being seen over the whole survey.

Thanks are due to the captain and crew of the Clipper Ranger for making us feel very welcome during our survey. The rain duly ceased as we left the berth, and the rest of the survey was blessed with slight to calm seas, which allowed for very productive surveying.
