"I strongly recommend this book to any biologist interested in behavioral ecology, sociality, or ornithology. It provides an excellent review of many of the primary cooperative breeding studies of the last two decades, points the way to future research, and touches on some of the more general problems in behavioral ecology. It would make a good addition to personal as well as to professional libraries." The Auk
