Outstanding full-color photos and a clear, readable text focus on the experience of wildlife biologist Lynn Rogers, who has spent 20 years observing black bears in Minnesota. The author describes Rogers' early interest in nature, university training and fieldwork, and gives a firsthand look at modern biology--where learning more about the life cycle and activities of the black bear involves high-tech tracking with radio collars and 24-hour field observations recorded on laptop computers.
