Last night's clear skies resulted in a big clear out of birds. A Yellow-browed Warbler around the Post Office in Baltasound was about the only decent migrant of the day. The Great Grey Shrike remained around the Baltasound Hotel, but birding was really hard work with a combination of a lack of birds and quite strong winds. We tried the west of Unst in the afternoon, birding around Lund, Westing and Ayesound. Snow Bunting and Whooper Swan were the only notable birds.
