SATURDAY 31ST MAY – Sunny spells and fresh South-westerly winds, 11C
Today was our final day exploring the Orkney Mainland before heading back south on the ferry. With light rain forecast to move in from the west, we decided to head to Marwick Head first on the west coast, to view the bustling seabird colony before the weather deteriorated. It actually remained fine for the hike up the cliffs and back and the wind wasn’t too strong, so the viewing conditions were pretty nice. We could see two huge flocks of Kittiwakes feeding just offshore from the clifftop, with both Arctic and Great Skua harassing them! The skua numbers have thankfully improved a lot this year compared to last, with both species being seen on every day of the trip and definitely more Bonxies around, hopefully a sign they are already starting to bounce back. There were some large rafts of Common Guillemots on the water too, but from the top, we would see many more, as this species is the most common nesting seabird on the ledges here. The sight and sound of any seabird colony is a real spectacle and again we were pleased to see that, while there were still lots of unoccupied ledges here, there were more birds than in the Birdflu-ravaged 2024. Razorbill, Fulmar and of course Puffin were here too, and we probably saw just into double figures of the latter.
Heading back down to the bay, we then drove all the way back across the islands to the East Mainland, and Deerness. With a South-east wind we figured it must be worth checking some migrant spots, not least because birds had arrived further north on Shetland. We drew a complete blank though at both Sandside and East Denwick, with very little to report from either location. In the afternoon we headed over to the Ring of Brodgar, so folk could have a walk around the standing stones. We were lucky here with an Osprey which flew in and started hovering over Loch of Harray next to the car park, providing a nice end to the trip. From here it was back to the Stromness ferry terminal for the ninety minute run down to Scrabster harbour, and then a 3hr drive all the way down to Boat of Garten for our final overnight.
FRIDAY 30TH MAY – Fine and sunny in light westerly winds, 15C
A beautiful, balmy day awaited for our final day on North Ronaldsay. With slack weather after the recent strong winds, we were hopeful that some migrants would drop but the day didn’t really pan out that way! We spent the morning checking a number of crofts with cover in the hope of unearthing something, centred around the south-east corner of the island. It was really lovely out and while the first couple of spots yielded nothing, we were enjoying the blue sky and turquoise seas. At Kirbest, we unexpectedly flushed a Snow Bunting along the road and up a driveway! The bird sadly didn’t seem that well – a young male bird different to yesterdays female on The Links. We watched it at close range feeding on the driveway and then left it be. After checking the Old Mill and another couple of spots down towards Bride’s Ness, we went through the gate in the sheep dyke and scanned the bay. Two Whimbrel flew off calling and there were sightings of Little Grebe and Reed Bunting among various other common waders and wildfowl noted. We then drove up to the surgery, and checked the garden there before heading down the track to Gravity. The small plantation held two Sedge Warblers which were no doubt breeding, but again no migrants could be found. After a quick look at Burray, we checked Ancum willows and with nothing much to show for the mornings efforts, we returned to the Obs for lunch.
For the afternoon we decided to sack off checking crofts and instead head up to the lighthouse and look for waders and seabirds. At Trolla Vatn 23 Bar-tailed Godwits were resting along with a few Turnstones and a single Dunlin. Walking up onto the top of the beach to view the bay, we saw several Black Guillemots and Eiders and by now were just happy to enjoy the beautiful t-shirt weather! We followed the stone dyke back to the communications mast and then walked out to the seawatch hide. Unlike in previous visits, there was no need to shelter inside the hide today and instead we scanned the sea from outside the hide. The view of Fair Isle was spectacular and offshore we watched a feeding frenzy of Arctic Terns and Kittiwakes. Eight Manx Shearwaters glided in and joined the throng and three Great Northern Divers included one really close full summer bird eating a crab. One of the Kittiwakes flew in and landed next to an adult Common Gull allowing for a rare and useful comparison of these two adult plumages side by side.
