Rick who lives a little farther south on the M5 collected me from Clevedon and we had an early morning drive to arrive in Birkenhead around 8.30am. Check-in formalities were soon completed and we joined the other foot passengers on the ferry bus, for the start of a new MARINElife survey.

Once on board, we were welcomed onto the bridge to familiarise ourselves with the layout and the Captain explained the route we would be taking on the charts and highlighted the areas where they had had sightings in the past. We then had time to view the historic waterfront of Liverpool, including the famous "Royal Liverbird Building", before returning to the bridge just before departure to begin surveying. 

Harbour Porpoise 2As we left the river mouth we were immediately in the middle of birds, Black-Headed Gulls, Great Black-Backed Gulls and many Cormorants all busily fishing. This was obviously a good feeding area and we looked hopefully for Harbour Porpoise but their tiny size and shy undemonstrative behaviour make them difficult to spot unless the sea is mirror calm.  Indeed on this survey we failed to spot any cetaceans but we had a report of one which appeared on the "wrong" side of the bridge for us!

However the trip was punctuated with views of seabirds to keep us busy, including: Great Skua; Arctic Skua; Fulmars, Guillemots; Kittiwakes and Common Gull. Common Gulls are not at all common in the area I live, so was pleased to see them.

This route across the Irish Sea looks like being a very productive route and will add valuable scientific data to the understanding of the UK coastline. A number of the crew had anecdotes of past sightings which bode well for future surveys.

Our thanks go to the Stena staff and crew of the Stena Mersey who made us very welcome and were enthusiastic about the MARINElife survey.
