After a trouble-free late Monday night check-in to the Britannia Seaways it was time to head to the cabins to get some sleep. With a departure from Felixstowe at 02:30, the boat was over half way to the Dutch coast by daybreak and we were welcomed onto the bridge by the very helpful crew at 06:30 to begin the survey.
With a force 4 to 5 wind and a good swell, it was always going to be a challenge to see the diminutive Harbour Porpoise - the most expected cetacean - and so it proved, with no sightings as we headed to the Dutch coast. October is a month of transition for the bird life. The breeding terns have started their migration south, and the wintering wildfowl are still on their way into the southern North Sea. We did spot a group of 12 Common Scoter, small numbers of Gannet and Great Skua as well as a couple of divers.

The river approach into Vlaardingen is always busy from a recording perspective. Large numbers of Cormorant were perched on the rocks of the breakwater and Mute Swan were feeding in the water along both shores. Small numbers of wintering Wigeon and Gadwall were seen alongside Mallard, Coot and Great Crested Grebe, now in their winter plumage. Wading birds were represented by groups of Lapwing, Oystercatcher and several Curlew on the shoreline. There was evidence of passerine migration with several groups of Greenfinch and Common Starling, as well as a single Northern Wheatear heading south over the boat.
Following the mid-afternoon departure from port in Vlaardingen the birds along the river were (unsurprisingly) similar to the eastbound leg; though, we did spot a Red-throated Diver and a female Common Eider (which were new birds for the survey) and a single Grey Seal made a brief appearance.
Reaching the open sea the wind had picked up further and reached force 8 for the crossing back to Felixstowe, which again hindered our attempt to record cetaceans. It was hoped that the wind may improve the chance of seeing Tubenoses and Skuas, but other than a couple of the latter it was left to just a few Gannet sightings for our recording sheets before nightfall.
Many thanks go to the staff and crew of the Britannia Seaways who made this a very enjoyable crossing.
