We arrived at Immingham dock to be met by the very efficient DFDS staff who quickly processed our tickets and arranged secure parking for our vehicles. We were then driven to the large and modern MV Clipper Point where we were made very welcome by the staff and shown to our excellent rooms.
After a very enjoyable meal we were shown to the bridge where
Captain Alan Leech and his officers made us very welcome. In the
excellent visibility and light winds we saw 2 Harbour Porpoise
before passing Spurn Point at the mouth of the Humber Estuary.
Before we started recording we had great views of an immature
Peregrine Falcon sitting on one of the new channel marker posts.
As we travelled east we saw several Red-throated Diver, most
of which were in summer plumage. Shortly afterwards we came across
a wheeling flock of 100 mainly adult Common Gull feeding above a
small pod of Harbour Porpoise. Late afternoon we had excellent
views of 2 Harbour Seal, both were swimming steadily east.

Towards evening I was delighted to see a pod of 5 White-beaked
Dolphin approach the ship before turning and diving away, always a
great species to see in this part of the North Sea. We also saw
several immature Great Black-backed Gull, small groups of
Kittiwake, a lone Puffin and unexpectedly a Great Northern Diver.
As we left the bridge that evening the setting sun was an
impressive sight against the high and diffuse clouds.

The following morning we started the survey just after dawn. It was overcast with a moderate SW wind. During the morning we saw a few Kittiwake, Lesser Black-backed Gull and the occasional Guillemot. Then late morning 40kms N of the East Frisian Islands we came across some adult Little Gull heading NE as well as a migrating flock of 35 Eider, 12 Dark-bellied Brent Geese and four Red-throated Diver. Then as we headed towards Cuxhaven dock we saw 5 Grey Seal swimming towards sandbanks exposed by the falling tide.
Captain Leech had kindly arranged permission for us to leave the
dock and I therefore went for a walk around the rough ground
surrounding the harbour in spring like weather. I was pleased to
see Fieldfare, Redwing and Blackbird presumably on their spring
migration while other migrants included a singing Chiffchaff and a
Black Redstart. Offshore during the afternoon we could see a steady
movement NE of Black-headed Gull, Cormorant, Shelduck and
Dark-bellied Brent Geese, this movement continued until dusk.

The following morning dawned grey with a SW wind force 5-6 and a 3 metre swell. This was quite challenging for surveying yet Charles found a Harbour Porpoise and a bull Grey Seal that spent a minute watching the ship before diving away.
The most unexpected bird species was a Stock Dove that we found keeping pace with the ship, after 30 minutes it accelerated away west into the strong SW wind. Seabirds included a steady passage west of adult Lesser Black-backed Gull. Presumably these had migrated N along the French and Dutch coasts before heading across to the UK for the summer. We also saw several groups of Kittiwake, often associating with summer plumage Razorbill, Guillemot and Puffin. We were also delighted to see the rare northern form of Fulmar usually known as Blue Fulmar.
As we left the bridge at dusk we thanked Captain Leech and his officers for their hospitality on this very enjoyable survey and we would also like to thank DFDS for their continued support of this survey route.
