More quality on our last full day

There was clearly an arrival of new migrants on Shetland today, with Redwing in particular streaming in in decent numbers. Our day included at least half a dozen Yellow-browed Warblers, a juv Red-backed Shrike, a superb Olive-backed Pipit on the roadside verge at Brake (while two Pallid Harriers remained nearby), and awesome views of the Alpine Swift at Cunningsburgh. At one point it switched from feeding in big loops relatively low over a hillside to heading out high above the harbour… at which point we realised it was being actively pursued by a Merlin! Fortunately the swift was sufficiently quick and agile to avoid becoming lunch!
