His work has elucidated new physiological mechanisms of temperature regulation of tropical versus temperate moths, bumblebees versus honeybees, beetles, dragonflies, flies, and butterflies, all done while at UCLA and Berkeley. Heinrich is distinguished by his research work in the comparative physiology and behavior of insects. From 1988 to 1989 he was a von Humboldt Fellow. In 1980 Heinrich accepted a position as a professor of zoology/biology at the University of Vermont. Between 19 he was a Guggenheim and Harvard Fellow.

In 1971, he accepted a position at the University of California, Berkeley where he became a professor of entomology. He then earned his Ph.D in 1970 from the University of California, Los Angeles. Heinrich attended Grundschule Trittau (1946–1950) and college at the University of Maine. He is the son of Ichneumon expert Gerd Heinrich. He has also written books that include more of his personal reflections on nature.

In addition to many scientific publications, Heinrich has written over a dozen highly praised books, mostly related to his research examining the physiological, ecological and behavioral adaptations of animals and plants to their physical environments. Heinrich has made major contributions to the study of insect physiology and behavior, as well as bird behavior. Bernd Heinrich (born Apin Bad Polzin, Germany), is a professor emeritus in the biology department at the University of Vermont and is the author of a number of books about nature writing and biology.
