After checking in the previous evening, we made an early departure of 4am out of Rosyth, and after enjoying breakfast courtesy of Boris, the on-board chef, we were up on the Bridge by 0745, to start recording sightings just south of the Farne Isles.

We caught a brief glimpse of a (probable) porpoise this morning, which was to be the only cetacean sighting on this voyage. This was more than made up for by a huge diversity of both seabird and indeed terrestrial bird species throughout the return trip. We recorded a total of 367 birds from 29 species, with adult & juvenile Gannet far outnumbering any other species seen.

The first day included the typical sightings of Fulmar, Lesser and Great Black-backed Gull, Great Skua, Arctic Skua, Kittiwake, and Sooty Shearwater.

There were however to be a few surprises in store for us, when we spotted a male Kestrel making circuits around the Bridge. To our astonishment later in the day, we established he was travelling in the company of two female Kestrel, all of whom had set up camp clutching to a corner of the vessel's vertical ramp.

To the south of the Whitby Bay area, the unchanging swell was suddenly punctuated by a rather comical group of 24 Grey Seal staring upward to us from the North Sea below! While the seabird count steadily rose through the day, we were greeted by a friendly Chiffchaff (and later another), who spent a good few hours flying around the Bridge windows, right in front of our noses.

While we were being entertained by a Blackcap and a Meadow Pipit darting around the deck beneath us, we took on-board the most unlikely passenger of the trip.  We were filled with bemusement as a lone Water Rail carefully stepped around on top of the ship's enormous freight containers, before later heading onward under its own steam.

On the second day, having left the Belgian coast behind, our return leg of the trip provided several more interesting species including Manx Shearwater, Arctic Skua, Common Tern, Sandwich Tern, Guillemot, Teal, Puffin and Brent Goose.

Once again, our thanks go to the Captain and his crew, for making us feel most welcome on-board, and we look forward to further trips in the future.
