Desmond Morris became famous with his "The Naked Ape." However, despite the mass popularity of that work, Morris was also a fine student of animal behavior. This edited volume, published in 1969, is an early classic in the study of primate behavior/ethology.
The various essays lay out the "state of the art" as of the late 1960s. Morris begins the book with an essay on the subject, to set the stage for the set of essays in this volume. J. A. R. A. M. van Hooff has a chapter on facial displays of apes and catarrhine monkeys; Wolfgang Wickler authored a chapter on socio-sexual signals among primates; John Sparks contributed a piece on grooming behavior in primates; Christine Loizos wrote a fine essay on play behavior in primates.
Other chapters: Thelma Rowell on social organization in primates; Hinde and Spencer-Booth on social companions' effects on mother-infant relations in rhesus monkeys; Jane Goodall on mother-offspring relations in Chimpanzees.
For its time, this was a nice volume, assessing the current status of primate behavior. I enjoyed revisiting this work, which I read so many years ago.
