Black Guillemot Peter Howlett 02Unusually for this route we departed late Saturday evening, so there was no surveying on the outward leg, and we retired to our appointed cabins to get some rest.

On Sunday morning following breakfast in the passenger restaurant we joined the crew on the bridge just at the Stena Mersey was beginning to depart Belfast harbour. A couple of Black Guillemot were seen as well as the only Eider of the trip. Many of these sea ducks winter in Belfast Lough, but numbers are lower at this time of year as they breed elsewhere.

The period at sea passing the Isle of Man to the east saw us recording all of the expected seabirds, including Manx Shearwater, Kittiwake, Fulmar, Guillemot and Razorbill, though we did only see one of the latter. We also saw a few terns, but the hoped for skuas never materialised.

Common Tern Peter Howlett 02It was looking like we were going to draw a blank on cetaceans, but as we neared Liverpool a pod of at least three Harbour Porpoise were seen well ahead of us. The survey was further enhanced by sightings of three separate Grey Seals.

Approaching Liverpool a couple more Common Tern were added to the tallies, presumably birds on feeding forays from the colony at Seaforth Dock. All in all we had a very enjoyable survey and are grateful to the crew of the Stena Mersey and port staff at Birkinhead for accommodating us during a very busy weekend for them.
