I am watching from the gateway along Gibbet Lane, which overlooks the flooded sandpit. Some kind person had dumped an old fence where I stand, so I had to move that first. I flushed the nearest gulls on to the water from the bank whilst I was working and I noticed one was very pale. As soon as I lifted by binoculars I realised it was the second-winter Glaucous Gull that has been around recently.
Ten Caspian Gulls today, which was a respectable total for late December.
