Natural History of the Racer Coluber constrictor

The racer, an active snake found across much of the United States, frequently crosses paths with farmers and hikers, yet it remains harmless despite the lingering fear many rural residents feel. Drawing on fourteen years of fieldwork that began in 1949 at the University of Kansas Natural History Reservation and later expanded to nearby prairies, the author creates the first comprehensive portrait of the species’ daily life. By setting live traps in meadows, pastures, and hayfields throughout Kansas and supplementing those captures with observations from western Oregon, California, and Louisiana, the study captures a broad picture of how this snake fits into varied landscapes.

The monograph walks listeners through the racer’s biology—its coloration, scale patterns, dentition, and reproductive cycles—while also noting its movements, temperature preferences, and hunting techniques. It examines the snake’s role in controlling agricultural pests, its interactions with predators and parasites, and how its habitat use shifts across the continent. All of this is presented with clear explanations of methods and richly illustrated data, offering an approachable glimpse into a species that has long been overlooked by science.
