Leaving Heysham the gulls were busy nesting on the low-pitched roofs of the dockyard and the tide was just coming in as we went up to the bridge. Departure was prompt on both days and after leaving the harbour we were welcomed by the captains Tim Broughton on the way out and Steve Cheeseman on the return trip.

Chicken Rock lighthouse Nuala Campbell 01The weather was good on both crossings and we had good views of the wind farm and gas platforms in Morecombe Bay, as well as the Isle of Man as we passed Chicken Rock lighthouse. There were a good many jellyfish on this trip, particularly the large Barrel Jellies.

There were a few solitary Grey Seals dotted along the route, plus on the outlying rocks near the lighthouse in Carlingford Lough, but not as many as during the winter trips. We were fortunate to spot a Bottlenose Dolphin as it leapt out of the water and had a frustrating time trying - and failing - to identify the whale that was just visible on the return trip. The deep channel on the Irish side of this crossing seems to be a place for cetaceans, plus the areas where water depth transitions from deep to shallow.

Fishing boat and gulls Nuala Campbell 01There were good numbers of Manx Shearwaters both skimming the water and rafting on both legs of the trip and lots of Cormorant and gulls sitting on the old wooden structures and the rocks as we left Carlingford Lough and Hooded Crows along the shoreline. However, from a bird perspective the groups of Black Guillemots and the Little Gull were a pleasure to see.

As ever the crew provided us with substantial breakfasts and evening meals on the crossings and there were ample refreshments on the bridge. We wish to thank both captains, their officers and crews for their helpful and professional support during the surveys.
