Greater Spotted Woodpecker

Woke up with a cold so took this shot from the comfort of my bed, a cloudy morning and a dirty window didn't help...
Out on the decking I have my 'Lardy Pole', basically a large branch stood on end in an old Christmas tree stand. Lard is then spread into all the nooks and crannies. This is the female, the male who was there earlier has a red patch on the back of his head.
Last year they hollowed a nest in a tree in the wood at the rear of the house, they raised two young and bought them to my 'Lardy Pole', this is pole no. 2 as last year they pecked no. 1 to pieces.
Lot's of territorial drumming going on.
