We had this male Great Spotted Woodpecker visitor in our Cherry Tree on 18 January 2018.
I often hear them, we have some large trees around, but it is great to see them in the garden. The red patch on the back of its head identifies it as adult male. A female has the red belly but not the red head patch and the juvenile’s belly is not quite as red and has a red crown to its head.
As usual you can click on the image to see it larger on Flickr. This time it is in an album of “Wildlife in our garden”.
