The Green Woodpecker is our largest native Woodpecker. The bird in this photo is a male as the centre of his black moustache is red. In the female it is all black.
They are a woodland bird and feed on insects, but are often seen feeding on ants on the ground, e.g. garden lawns and pastures.
Breeding starts in late April in a hole in a tree. They have 1-2 clutches a year, producing 4-9 young. They fledge in approx. 23-27days.
Their call is a loud cheerful laugh, or "yaffle".
