Spent some time looking through the gulls and found one of the BLACK HEADED GULLS from yesterday which was rung. Also a very odd looking HERRING GULL with a deformed beak. The lower mandible was longer than the top one.
At one point all the birds where startled as a PEREGRINE flew in rather fast to my right. I would not like to gusste-mate it's speed, but it was nocking on rather.
The following is the recovery record for one of the birds yesterday.
