'Tool Use in Animals: Cognition and Ecology may well be the new benchmark text for animal cognition. This book is clear, well-written, suitably broad in its approach, and delivers information that covers a review of the field in addition to new data. Its appeal will encompass readers from various connected academic disciplines, and [it] is an appropriate text for professionals and for students. This is an important and timely offering, and a happy addition to my library.' Kerrie Lewis Graham, American Journal of Physical Anthropology
