Carpenter,Clarence Ray. — Naturalistic behavior of nonhuman primates.

Pennsylvania, Pennsylvania State University Press, University Park, 1964. 454 pp. Ills. Orig. hardcover (clothbound). 8vo.A foundational book by Clarence Ray (C.R.) Carpenter, a pioneer in the field of primatology and animal behavior. The book compiles his groundbreaking field studies from the 1930s and 1940s, which shifted how scientists studied monkeys and apes by observing them in their natural habitats rather than strictly in laboratory settings. Carpenter was among the first scientists to conduct systematic, long-term observations of wild primates. He established rigorous standards for habituating wild groups, recording data accurately, and avoiding human interference with animal behavior.
