Spent the morning at Sumburgh Head looking for the Two-barred Crossbills (the flock had steadily been rising all week - from 6 upwards), after looking around the lighthouse and the car park areas, found the flock (now 18, inc 2 males !!) around the walls in the Parks, sheltering from the wind, with 9 Common Crossbill. Also, Melodious Warbler in the roses at the Lighthouse.
