Gerard Gorman is a global authority on the Picidae. He has published numerous papers and six previous books on this fascinating family of birds, including Woodpeckers of the World: The Complete Guide (Helm 2014) and The Green Woodpecker (Picus Press 2020). For the past 30 years he has travelled the world studying woodpeckers, believing that time in the field is the only way to really get to know them. In this book, the author augments many hours watching wrynecks with comprehensive literature research, creating what will surely be the definitive work on the species. Gorman lives in Budapest and is a founder member and current leader of the Hungarian Woodpecker Working Group.
