Red Throated DiverWe arrived at the terminal for the inaugural survey on this route keen to see what we would record.  The Seatruck shore staff were very helpful and we were soon on board the Seatruck Panorama, where the captain and crew soon made us feel at home.

We were on the bridge whilst the navigations to get the vessel out of the dock were undertaken, and we started surveying as the boat left the Mersey mouth soon after.  We soon had a few seabirds, including Kittiwake and Guillemot.  The highlight of the early stage of the recording was several Little Gull, including some zebra-striped first year birds.

Harbour PorpoiseAs we traversed the seas off the North Wales coast we steadily added to the species recorded, though numbers were generally low except for Kittiwake which were seen in some sizeable flocks.  Razorbill also increased in frequency as we headed further east.

Things picked up as we got closer to Dublin.  At least three Harbour Porpoise were picked out in the calm seas, two of which we were able to show to the captain as they surfaced close to the ship.  An adult Mediterranean Gull and a Great Skua were welcome additions to the bird list for the trip.

After a night exploring Dublin we took a taxi back to the Seatruck terminal early on Friday morning, and the captain and crew of the Seatruck Power were again very friendly. 

Grey Seal 1The conditions again looked good for surveying and we were hopeful.  We saw a couple of Black Guillemot as we left the harbour,  A skua seen harrying a Kittiwake proved to be a juvenile Arctic Skua, a rare opportunity to see one so well in Irish Sea waters.  Some passerine visible migration was also observed over the sea including several Swallow, a House Martin and a Goldfinch.

As we approached Liverpool again a Grey Seal surfaced a couple of times in front of the boat.  A small group of Common Scoter circled in the distance and some terns were observed.  Large numbers of gulls and Cormorant lined the beaches but we restricted our counts to the birds on and over the sea and river.

We docked early evening and warmly thanked the captain and crew for their help and friendly welcome on what had been a successful inaugural trip.
