This comprehensive reference manual investigates the identification of animal presence through the systematic analysis of tracks, droppings, and other physical signs left in the wild. The author, Preben Bang, utilizes decades of field observation and biological expertise to provide a structured framework for tracking mammals and birds. By categorizing signs based on morphology and habitat, the text enables readers to interpret the movements and behaviors of wildlife without direct observation.

This guide is widely regarded as a definitive resource for naturalists and field biologists due to its rigorous attention to anatomical detail and clear, diagnostic illustrations. The work provides a high level of technical utility for both amateur trackers and professional researchers seeking to document animal activity in diverse environments.
