Dusky Warbler still on North Denes

On Thursday 12th November, I walked back to the first shelter belt by the slope just north of the Oval, another birder was there, I immediately heard the chacking of the super Dusky Warbler and we had glimpses of it in the bracken at the back showing fairly regularly for a second or two views. It then flew over to the second shelter belt and showed similar views by the bracken here too before I had to leave for work at 8.10am.
