Yellow-browed Warbler?

Had a call from John Hudson this afternoon, he saw what he thinks might have been a Yellow-browed Warbler at Westfield Pill yesterday. It was along the new zig-zag piece of cycle track that runs down from the Neyland to Cleddau Bridge road to the Pill, in the scrub by the picnic bench. It looked settled and feeding well. I will hopefully check it out tomorrow morning.
