Rainforest monkeys

An Ecological and Behavioural Study of the Pig-Tailed Macaque (Contributions to Primatology, Volume 21, pages 1-259, published by Karger, Basel, Switzerland, 1986).

From the review by Paul E. Simonds (American Journal of Physical Anthropology, January 1987):

“Caldecott has made the most of his opportunities in gathering the data and presenting a full picture of the ecological setting in which pig-tailed macaques must survive, and he does a careful analysis of their maintenance activities in relation to the ecology … The analysis is very interesting, showing that pig-tailed macaques are quite different than the other species of macaques that have been the model for ‘the macaque’ for so long … [The book] stands as another milestone in our understanding of primate diversity and adaptation.”

From the review by Charles H. Southwick (Animal Behaviour, Volume 35, 1987):

“Pig-tailed macaques are well known from many laboratory and captive studies, but their natural ecology and behaviour are relatively unknown.  They are elusive and shy, difficult to find, and largely terrestrial in dense forest cover … The book emphasizes feeding and foraging behaviour, and places considerable focus on the composition of the forests … Caldecott concludes that pig-tails survive ‘by harvesting rare, highly nutritious food items during almost continuous foraging travel’.  Their behaviour and social organization reflect the ecology of the Malaysian rain forest … Caldecott closes with a plea for tropical forest conservation…  He is concerned that Macaca nemestrina, within a few years, could be ‘restricted to small populations in remote mountainous areas’.  This book is recommended for all primatologists and also to many students of animal behaviour, especially those interested in the behavioural ecology of primates in tropical forests.”

From the review by Wolfgang Dittus (Zeitschrift fur Tierpsychologie, Volume 76, 1987):

“Owing to the practical difficulties in following and habituating these macaques in their rainforest habitat, certain details of ecology, behavior and especially socio-demographic relationships in this species will remain a challenge for future investigators.  This thoroughly scholarly and well written book … nevertheless stands as the major reference for this species for mammalogists as well as any others with interest in the rainforest ecology of the Sundaic region.”

From the review by Yarrow Robertson (American Journal of Primatology, Volume 12, 1987):

“This is the first long-term study of the pig-tailed macaque.  The professionalism and breadth of background data are sufficient to ensure that this book will be the classic academic monograph on the behaviour and ecology of Sundaic pig-tailed macaques … It is therefore essential reading for all behaviourists working with captive pig-tailed macaques, and is highly recommended also to all researchers studying the behaviour and ecology of macaques.”
