|1st-summer Caspian Gull Thames Barrier Park, London 22nd July 2017|
Other than this bird, it has been nice to find Yellow-legged Gulls really locally. No juveniles yet in Rotherhithe but the mud by the Hilton Hotel continues to draw them in - three on 22nd July (two 2nd-summers and a 1st-summer) being the highest count and my first juvenile here today - and a regular adult on Greenland Dock continued to linger until 16th July.
