Woodpecker Feeding on Long-horned Beetles

This photo (taken in the Bieszczady Mountains, Poland, in November 2008) shows the marks left on a fir tree Abies alba by a woodpecker which has been searching for the larva of long-horn beetles (Rhagium species). The larvae of these beetles lie just below the soft bark surface. It is not clear which species of woodpecker did this, but based on the species present in that area and the size of the beak marks White-backed Dendrocopos leucotos and Great Spotted Dendrocopos major are the most likely candidates.
