It was a pied woodpecker, not the large green woodpecker, but another kind.

The only sound is the astonishing cackle of a green woodpecker.

Under the vault of the trees the cry of the green woodpecker has magic sounds.

And despite the dull grey sky, birds sing brightly and a green woodpecker sweeps between the trees.

Another local word I have not heard elsewhere is "eckle," meaning a green woodpecker or yaffel.
