Tony Greenfield grew up in England, and after graduating from the University of Liverpool with a degree in geography, eventually settled on the Sunshine Coast of British Columbia. For thirty years Greenfield operated Whiskeyjack Reforestation Ltd, a tree-planting company, which afforded him the opportunity to spend a life in the mountains and visit every remote corner of British Columbia. Since 1979 Greenfield has been involved with the Sunshine Coast Natural History Society and he was a founding member and president of the BC Field Ornithologists. Since 2003 Greenfield has operated Whiskeyjack Nature Tours and offers excursions to Panama, Arizona, Utah, British Columbia and the Yukon. Greenfield has written A Hiking Guide to the Trails of the Lower Sunshine Coast and is one of the authors of the forthcoming Guide to the Birds of British Columbia.
