Dirk Hilbers (NL, 1976), set up the Crossbill Guides Foundation and travels Europe to research the guidebooks. This is the 18th guide on which he has worked. As a biologist, when not in the field, Dirk Hilbers is a free-lance writer and lecturer in the field of environmental ethics.
John Cantelo (UK 1950) taught History and Social Studies before semi-retirement allowed him to focus on his other enthusiasm, birds and wildlife, by field teaching for the UK nature conservation organization the RSPB. For the past ten years he has helped edit the Crossbill Guides and for rather longer has been a regular visitor to southern Spain. He is an active member of the Andalucia Bird Society and Vice-President of Kent Ornithological Society!
