Great Spotted Woodpecker - Photographed this one drumming away in Allestree Park Derby England. Very rare in Ireland, only a very few reported. The drumming sound is made by the male, using a dead dry tree that generates a good volume, to attract a female. The sound can travel over hundreds of meters in favourable conditions. Sometimes know as the Pied Woodpecker.
