Over the road were 4 Slavonian Grebe, 3 Red-throated Diver, 4 Red-breasted Merganser and a winter plumage Black Guillemot.
A drive south to Loch of Spiggie gave good, but distant views of the wintering Pied-billed Grebe and 5 Eurasian White-fronted Geese. A Twite gave a couple of fly-overs.
A bit of light dipping followed, with no sign of the Rosefinch or the Tundra Bean Geese. More success back in Lerwick with an adult Glaucous Gull, juvenile Iceland Gull and 3 Black Guillemot. Of the latter only a winter plumage bird was close enough for photographs.
Back at the owl for more another look and it was more active as it got closer to dusk. Plenty of preening and yawning, but unfortunately it didn't move out into the open. A 'real' Rock Dove was feeding in the gardens.
An excellent trip!
