Although Gerd Heinrich, a devoted naturalist, specialized in wasps, Bernd Heinrich tried to distance himself from his "old-fashioned" father, becoming a hybrid: a modern, experimental biologist with a naturalist's sensibilities.

In this extraordinary memoir, the award-winning author shares the ways in which his relationship with his father, combined with his unique childhood, molded him into the scientist, and man, he is today. From Gerd's days as a soldier in Europe and the family's daring escape from the Red Army in 1945 to the rustic Maine farm they came to call home, Heinrich...

Heinrich involves us in his quest to get inside the mind of the raven. But as animals can only be spied on by getting quite close, Heinrich adopts ravens, thereby becoming a -raven father, - as well as observing them in their natural habitat. He studies their daily routines, and in the process, paints a vivid picture of the ravens' world. At the heart of this book are Heinrich's love and respect for these complex and engaging creatures, and through his keen observation and analysis, we become their intimates too.

Heinrich's passion for ravens has led him around the world in his...

How does the animal world deal with death? And what ecological and spiritual lessons can we learn from examining this? Bernd Heinrich has long been fascinated by these questions, and when a good friend with a terminal illness asked if he might have his "green burial" at Heinrich's hunting camp in...

All bodily activity is the result of the interplay of vastly complex physiological processes, and all of these processes depend on temperature. For insects, the struggle to keep body temperature within a suitable range for activity and competition is often a matter of life and death.

A few studies of temperature regulation in butterflies can be found dating back to the late 1800s, but only recently have scientists begun to study the phenomenon in other insects. In The Thermal Warriors Bernd Heinrich explains how, when, and in general what insects regulate their body...

Why do ravens, generally understood to be solitary creatures, share food between each other during winter? On the surface, there didn't appear to be any biological or evolutionary imperative behind the raven's willingness to share. The more Bernd Heinrich observed their habits, the more odd the bird's behavior became. What started as mere curiosity turned into an impassioned research project, and Ravens In Winter, the first research of its kind, explores the fascinating...

This engaging chronicle of how the author and the great horned owl "Bubo" came to know one another over three summers spent in the Maine woods--and of how Bubo eventually grew into an independent hunter--is now available in an edition that has been abridged and revised so as to be more accessible to the general reader.

From flying squirrels to grizzly bears, and from torpid turtles to insects with antifreeze, the animal kingdom relies on some staggering evolutionary innovations to survive winter. Unlike their human counterparts, who must alter the environment to accommodate physical limitations, animals are adaptable to an amazing range of conditions.

Examining everything from food sources in the extremely barren winter land-scape to the chemical composition that allows certain creatures to survive, Heinrich's Winter World awakens the largely undiscovered mysteries by which nature sustains herself...

In a book destined to become a classic, biologist and acclaimed nature writer Bernd Heinrich takes readers on an eye-opening journey through the hidden life of a forest.
