On a course in Kirkwall on Friday and the timing was right for a dusk visit to Graemeshall Loch. Whilst the Bittern didn't show the finder (KH) did, unfortunately he didn't bring his Franklin's Gull with him either.
Of interest were the 11 or more Grey Heron's that flew out of the reed bed as dark approached. A duck and then a drake Goosander appeared, Orkney tick for me. A Kestrel and a Sparrowhawk hunted the loch side.
