Believed to be a hybrid Lesser-black backed Gull x Herring Gull due to large mirrors visible in wings, lack of bold red eye ring and no bleeding of red spot on upper mandible.

I thought maybe a chiffchaff (autumn juvenile male as quite bright lemon yellow) or if not a willow or wood warbler? Found close to Battersea Park. Sadly victim to a window collision.

Unsure if is a short toed treecreeper or not
