Need help - poss chiffchaff or willow warbler

  1. Hi all

This little bird landed on my garden wall yesterday and we need help to ID it, I think it's a chiffchaff but also looks like a willow warbler, it made no noise and was rummaging in the brambles in an overgrown alleyway. Anyway, nice surprise as at first sight i thought it was a robin, pretty exciting if it's either one as we live in central southsea and we only usually get gulls and wood pigeons in our garden! Any help would be truly appreciated Bird
