Tree Stump Worked by White-backed Woodpecker

Many (but not all) woodpeckers peck and hack into trees to find invertebrate prey. With practise, and local knowledge, the signs that woodpeckers leave when foraging on and in timber can often be assigned to exact species. This image shows a tree stump that has been worked by White-backed Woodpecker Dendrocopos leucotos. This kind of systematic, total shaving of dead stumps is typical for this species when it searches for wood-boring beetle larvae. Note the wood-chips and 'sawdust' on the ground nearby.
