Evidence of Great Spotted Woodpecker In action, Witnessed one in flight near area in woodland, where these pictures were taken.
No interactions present.
Not sure it is possible to be certain of which species from the pictures provided although GSW is the most likely.
I must admit, I'm hazarding a guess, but the GSW is the prominent species of woodpecker in this woodland, and I spotted a GSW about an hour before these pictures were taken, near this area
