This book investigates the ecological and behavioral patterns of the capped langur (Trachypithecus pileatus) within the specific context of Bangladesh. Stanford draws upon extensive fieldwork to present a comprehensive overview of the species' adaptations and social structures in its natural habitat.

This work is recognized as a significant contribution to primate behavioral ecology, particularly focusing on a less-studied species in a specific geographic region. It is likely to be valued by researchers and students in primatology, zoology, and conservation biology for its detailed field data and analytical approach. The book provides a foundational text for understanding the capped langur's place within its ecosystem.
