More foraging work by Black Woodpecker Dryocopus martius. Some of the holes are burrows of wood-boring beetles, others are holes made by the woodpecker to access the beetles. The green cross is not a cry for help from the beetles or the tree ! - it's a trail marker. Buda Hills, Hungary, September 2014. Gerard Gorman
