An early visit to Skaw revealed nothing new. Norwick produced a Spotted Flycatcher, a Sedge Warbler and the Reed Warbler had remained overnight and briefly sang. A summer-plumaged Great Northern Diver was heard calling in Haroldswick bay this evening - brilliant! A Rock Pipit present on the rocks there looked good for a littoralis.

Based on today's better views in better light and the resultant images showing the true extent of the wear on its primaries and being a close match to previous Spring Reed Warblers seen and trapped on Shetland its fair to say the pendulum has firmly swung to this being most-likely a cold scirpaceus. With many thanks to MSC, JFC, PVH, PK and RR for all openly sharing their thoughts/knowledge.
