Stena MerseyWe were welcomed aboard the Stena Mersey by the captain and crew and were on the bridge in good time for departure at 10.30.  A number of Little Gulls were seen in the river, and on the outward journey we had no fewer than 32 of these charming birds.  This is the peak time of year for these birds passing through the area on their way to Baltic breeding grounds.  Six seals, 5 Grey and a Common, were hauled out on a sandbank and we had a number of other good sightings as we headed past Formby Point including a couple of Little Terns and a drake Common Scoter.

Large stretches of water either side of the Isle of Man were rather quiet other than for Guillemots, perhaps because bad weather to the south had blocked passage of seabirds.  We did though have excellent views of a dark morph Arctic Skua that lifted off from right in front of the boat.

Little Gulls

As we approached Belfast Lough seabirds began to pick up again including flocks of auks and small groups of Manx Shearwaters.  The first Puffin was very welcome and we were pleased to see five of these charismatic seabirds.  Entering the lough we had two Red-throated Divers, the only ones of the survey, and then as expected we picked up a few striking summer plumaged Black Guillemots.  We couldn't count what we saw on Belfast Lough RSPB reserve, but it was good to see a pleasing selection of birds including several species of waders and a few Swallows.

On the return we were grateful for the Captain's permission to survey between first light at around 5.45am and coming alongside the mooring at 6.15.  This was rewarding with at least 49 Little Gulls, some very close to the boat.  We then thanked the Captain and crew for their assistance for what had been the most successful survey on this route so far for seabirds.
