Other than Sedge Warbler Yellow-browed has been the most common warbler on the Old Nisthouse patch with three. A Chiffchaff did finally join the list with this interesting bird. The call was slightly odd, but not tristis and whilst it was quite a brown looking thing to my eye it did not have the right look.
Nice seawatching with a good few Great Northern's passing Northside.
...actually the day after this big blow which produced a few small skuas. After Northside I went on The Brough and had a single distant Sooty.
