The regular first-winter Caspian Gull was again at London Wetland Centre this afternoon. This is the bird I first saw on the adjacent River Thames on 8 January and then at LWC the following weekend. Presumably it's spending most of its time in this area.
Other birds today included two Bitterns, two Water Pipits and a couple of female Pintail. Year ticks were Peregrine (two sat on Charing Cross Hospital and viewable distantly from the Peacock Tower) and my first Mistle Thrushes of 2017.
