Book: Developments in Woodpecker Biology

This recently published book contains 8 papers by different authors on a range of subjects including woodpecker systematics, morphology, cognition, ecology, breeding biology and population densities. It is edited by Hans Winkler and published by the Biologiezentrum des Oberosterreichischen Landesmuseum in Linz, Austria. I am honoured to have a paper of my own included: Foraging signs and cavities of some European woodpeckers (Picidae): Identifying the clues that lead to establishing the presence of species.
