The Roger Tory Peterson Institute of Natural History (RTPI) is the only official institutional steward of Roger Tory Peterson's body of work and his enduring legacy. It is our mission to successfully foster understanding, appreciation, and protection of the natural world in the spirit of Dr. Peterson's many accomplishments. By providing people with opportunities to engage in nature-focused art, education and conservation projects, we promote the study of natural history and its connections to human health and prosperity.
