The Green Woodpecker is a relatively rare bird in Scotland where photo 2 was taken and indeed, it was only reported as breeding in Scotland as recently as 1951. It is much more common in England where its favoured habitat of broad-leaved woodland with grassy clearings occurs more frequently.

Note the red on the crown and the black round the eye. In photo 1 the red malar stripe indicates it is a male while photos 3 and 4, with the black malar stripe indicates a female.
