KittiwakeWe arrived at Felixstowe on Monday evening and were escorted to the ship shortly after it docked to settle down for the night. We awoke before dawn, had breakfast and were invited onto the bridge. The North Easterly wind had created a mild swell on the North Sea that subsided as we approached the Dutch coast. Gannet, Guillemot and Kittiwake were in evidence as we started our survey, the Guillemot still in winter plumage but some of the Gannet had already started to develop their breeding finery.  Captain Luffe joined the bridge and advised us that he had seen in the past few weeks a whale surfacing between his ship and another vessel close by.

Six miles from the mouth of the River Maas the sea swell had subsided and we had our first sighting of a cetacean. Two dolphins, one adult and one juvenile briefly appeared on the starboard side of the vessel, frustratingly too quick to identify with any certainty.  Ten minutes later in the distance we had a further sighting, a large light grey-brown animal with a very slow roll and thick based dorsal fin, possibly a Northern Bottlenose Whale.

HarbourPorpoise Felix02/13We then entered the river section of our survey. Herring Gull and Black-headed Gull were evident. Along the river bank, large numbers of Gadwall, Wigeon and Pochard were encountered; many of them appeared to have paired up ready for the breeding season.  We docked at the terminal in Vlaardingen and started to compile our sightings.

Daylight hours would enable us to survey the 30 miles west of the Dutch coast. Two miles from the river mouth we encountered a Harbour Porpoise. Seven animals were seen over the next six miles.

With the light fading, we left the bridge after a very rewarding survey.

Our thanks go to DFDS Seaways and Captain Luffe, his Officers and crew for making this survey possible.
