On 29th May 2020, my partner, Pauline Hogg, found a Great Spotted Woodpecker Dendrocopos major nest at Fairburn Ings RSPB, Yorkshire. We visited the following day and waited by the tree, which was situated by a busy public footpath. Within minutes, a Blue Tit Cyanistes caeruleus quickly came and went from the nest hole and I suggested that it was an old woodpecker nest that was now inhabited by Blue Tits. Pauline assured me that a young woodpecker had been peering out of the hole the previous day and so we waited to see what was happening.
