Pied Woodpecker eating peanuts

This woodpecker has started coming to eat peanuts from the feeder hanging from our crab apple tree. When I saw him this morning, I hastily put the telephoto lens on to my camera.... Unfortunately I didn't have time to set up a tripod so none of the 20+ pics I took is in perfect focus!
I know he is male because of the red patch on the back of his head, which females don't have; I hope a female will turn up soon so we have a breeding pair!
(Officially he is a Great Spotted Woodpecker, but they were Pied Woodpeckers when I first started learning about birds!)
