At Amroth this evening all the usual were present. Common Scoters (500+), Great Crested Grebes (c30) but only 2 Red-throated Divers. A pleasent surprise was large gull roost, about 800 birds, out in the bay. This gave me a chance to put into practice what I learnt from yesterdays Gull ID day with Dave. The roost was predominately Black-heads, mostly adults but a several 1st winters, a few Herring (adults, 1st, 2nd, 3rd winters) and Great Black-backed and small numbers of Common Gulls (adult and 1st winters) and Kittiwakes. Could well of been something else in the roost but poor light forced me to give up and head home!
