Having received our customary warm welcome on board the Stena Performer, we set sail with good expectations from the Port of Heysham in dry, calm conditions with partly overcast skies, good visibility and light southerly winds. There was little activity to record as we passed through the area of wind farms where we left behind the Herring Gull and Lesser Black- backed Gull and began to encounter Gannet, Guillemot and Kittiwake.
A highlight of this leg of the survey was two
Red-throated Diver in flight and a flock of a dozen Common Scoter
flying low over the water. With the Isle of Man coming into
sight we started to record Manx Shearwater, initially the odd one
here and there and then in increasingly larger rafts. A
gathering of 100 Manx Shearwater accompanied by Kittiwake,
Guillemot and Common Tern raised hopes of possible cetacean
activity but sadly this wasn't to be the case. Our
disappointment was short lived, however, as Fraser briefly glimpsed
two Harbour Porpoise 100 metres from the ship.
We continued towards Belfast with occasional sightings of Fulmar, Gannet, Swallow, Common Tern and Guillemot. By the time we entered Belfast Lough the weather conditions had deteriorated but despite the rain and reduced visibility we began to log Black Guillemot. Passing the reserve at Belfast Harbour we logged both Sandwich Tern and Common Tern and saw a number of other species including Shelduck, Coot, Lapwing, Black-tailed Godwit, Dunlin, House Martin and Sand Martin.
After a comfortable night's stay in Belfast we were warmly welcomed on board the Stena Precision for our return leg to Heysham. With the sun shining and conditions calm, we were entertained by Black Guillemot and a Harbour Seal in the harbour as we waited to set sail. Moving through Belfast Lough we recorded a Grey Seal. Excellent visibility gave us clear views of the Mull of Galloway. Our return leg was characterised by long periods of very little seabird activity (no doubt due to due to breeding birds being at their nesting sites at this time of year) with flurries of activity as we occasionally came across rafts of mixed species including Manx Shearwater, Kittiwake, Guillemot and Common Tern. Our "bird of the trip" was a dark phase Arctic Skua flying past.
At the Point of Ayre, to the north of the Isle of
Man, Fraser spotted four dolphin fins amongst some Gannet feeding
activity but the glimpse was so brief, looking into the sun, that
he was unable to identify the exact species.
As we entered the wind farm area, approaching Heysham, we were joined on the bridge by a Buff-tailed Bumblebee queen who we rescued and released, hoping the gentle westerly winds would carry her to land.
We would like to thank the Captains, the officers and crew of the Stena Performer and the Stena Precision for their continued generous hospitality and support and also the Jury's Inn, Belfast for kindly providing us with accommodation.
