Biologists use animal radio tags for two main purposes: to locate and study animals in the field, and to transmit information about the physiology or behaviour of wild or captive animals. These uses are described respectively as `radio tracking' and `radio telemetry'. This book will be invaluable for scientists in all branches of ecology and wildlife research, both in showing ways in which radio tagging can be of use and in giving practical details on how to use this technology.

Robert Kenward started radio-tracking wildlife in 1974, monitoring released goshawks as a part of a thesis study at Oxford University. After learning to build radio-tags for projects in Sweden, he became a government biologist, working mainly on raptors and squirrels. More than 50 of his publications involve radio-tagging, including the Ranges suite of analysis software.
...this book is of definite value to any and all researchers that are considering or applying telemetry to their research. It is highly recommendable for its thoroughness, timeliness, and user friendly organization. Those already owning the earlier volume should still consider purchasing this new version. Roger D. Applegate for THE CANADIAN FIELD NATURALIST (2002) "This book is undoubtedly the most comprehensive and up-to-date work available on wildlife radiotagging, and would be essential reading for anyone considering undertaking a radiotagging project." IBIS (2001) "Kenward has reached a nice middle ground - unlike most manuals we encounter in daily life - by writing in plain language yet still including the abundant technical details needed to understand the field. These details are aimed at addressing the litany of questions expected from first time trackers, as well as those experienced field workers branching out to new techniques.
