"In summary, this is a thorough and concise book on mixed-species animal groups, and functions as a single resource for anyone who is interested in the study of this topic. It is very useful for both undergraduates and post-graduates, as well as for those outside of academia, and so I would thoroughly recommend it for a university library and for anyone who is considering research within this area." --Primate Eye "...it is a rich, although not exhaustive, source of information on MSGs. ...I enjoyed reading it and learned a lot, and fully recommend it to everybody interested in mixed-species groups." --The Quarterly Review of Biology "I found the book fascinating in its breadth and now have a much broader and deeper appreciation of mixed-species groups. The authors present frameworks that can be used to guide future research, highlight future research questions, and point out how new methods may enhance our knowledge of both mechanism and function." --Primates "It will be useful to a broad readership, from students who look for a thorough introduction to the phenomenon to researchers and university lecturers who want to have a single resource on mixed-species troops at hand…I enjoyed reading it and learned a lot, and fully recommend it to everybody interested in mixed-species groups." --Primates

Functions as a single resource for readers inside and outside of academia on mixed-species groups, serving as a foundation for future research in this field Begins with an empirical summary of mixed-species distribution and reviews how the theories explaining their adaptive benefits are supported by the evidence Includes many aspects of mixed-group behavior (e.g. foraging, communication, collective decision-making, dominance, social roles of species and leadership, relationship to conservation) that were not previously or easily accessible
