The Three-toed Woodpecker

As its name suggests, it has just three digits on each foot, whereas other woodpeckers have four!
However, it is very agile at climbing trees and is the worst nightmare for wood-eating insects, especially the Bostryche, which it fancies!
Be quiet, as its drumming - the way it communicates by tapping its beak on trunks or branches - is barely audible. Nevertheless, the Nature Reserve is one of the few areas where it is still present.
