Yellow-browed along North Denes slope belatedly found by me!

On Sunday 12th October, After hearing of Crossbills in Belle Vue Park, I drove there and saw Rob H no sign of the Crossbills but driving back along North Parade by some Pines I heard a Yellow- browed Warbler on the slope, at the time I spun round and saw a Pied Wag fly off and put it down to that but I should have trusted my initial ID as one was found there less than hour later. Later on I looked around Corton Wood and heard Crossbills fly over but I didn't see them.
