A drive up Saxa Vord hill first thing produced stunning views of Herma Ness and Muckle Flugga. Birds encountered along the way included two Twite and the ubiquitous Meadow Pipit,  Skylark, Starling and Bonxie. A little later, we stopped at the Nikkavord Lea housing estate where s group of Crossbills had been found in the shelter belt behind the houses. An adult male and an immature Two-barred Crossbill were initially evasive but then showed very well, along with an adult female Common Crossbill.
Back on mainland, a short diversion over the moorland road to Graven unfortunately failed to produce either Red Grouse or Mountain Hare. However a brief roadside stop a little further on produced breeding dvidence for both Greylag Goose and Wigeon.
Next stop was Lerwick Harbour where the only land bird was House Sparrow. However a boat trip starting there quickly produced Black Guillemot, Great Skua, Razorbill, Great Black-backed Gull and a sizeable gathering of Herring and Lesser Black-backed Gulls (plus Grey Seal).
The trip to Noss cliffs allowed exciting close encounters with Gannets, Guillemots, Fulmars, Shags, Arctic Terns and a few Puffins and Kittiwakes. Best sighting was of a Guillemot with a "jumpling" by its side making their way out to sea.
The afternoon ended with a walk along the shore near Boddam. The cliffs there held breeding Fulmars and Rock Doves. There were Rock Pipits along the cliff edge and a mixed group of Shags and Cormorants on a rock pillar. Probably the most notable sighting was of two Common Sandpipers flying along near the water's edge. A Painted Lady and a couple of Rabbits were on the grassy clifftop.
Back at Sumburgh, three Mallards were on a small field pool adjacent to the Sumburgh Hotel.
