Since there have been a few caspian gulls around down in Attercliffe I decided to head down to see if I could see one, and to do some proper gull watching to improve my ability in this area. I bumped into a couple of other birders there and we watched the gulls on the tip roof. We picked out one that looked good and I was fairly confident, but it was not, and I should have seen it really given it has a whopping great big Gonys angle, but in the scope it was not that clear. The bird in question was a 2nd Winter Greater Black-Back but with a dark bill. It was an important mistake to make, as it helps me learn and hopefully wont happen again. It also gave me a chance to look into different ages of gulls in the field, something I have not really done before.
