Bernd Heinrich (born April 19, 1940, in Germany) teaches in the zoology department at the University of Vermont and is the author of a number of books about nature writing, zoology, ecology, and evolution. In Bumblebee Economics, Heinrich researched temperature regulation and energy economics in bumblebees, showing that bumblebees maintain a body temperature above the ambient environmental temperature. Heinrich's research has also made major contributions to the study of ravens and owls.
