Black Woodpecker foraging cavity

This huge (approx 20cm x 15cm) freshly made hole is the work of Black Woodpecker (Dryocopus martius). In Europe only this species makes such holes. The edges of the hole are cut with almost mechanical precision by this woodpecker with its sharp, chisel-shaped beak. In most cases such holes are made when tree-dwelling carpenter ant colonies are sought. Buda Hills, Hungary, April 2015 (Gerard Gorman).
