Black Woodpecker foraging hole

In this photo is a newly excavated hole made by Black Woodpecker Dryocopus martius. This is clearly a foraging hole not a nest-hole. Nest-holes are more precise, smaller, oval or roundish. This large, vertical, slit-shape is typical for this species: no other woodpecker (indeed no other animal) in Europe makes such holes. These are usually hacked into living trees that have hollow cores due to rot and where invertebrate prey resides. Pest County, Hungary, March 2015, Gerard Gorman.
