Why do ravens, generally understood to be solitary creatures, share food with one another 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 odder the birds' behavior became. What started as mere curiosity on Heinrich's part turned into an impassioned research project. This book explores the fascinating biological puzzle of the raven's rather unconventional social habits. Bernd Heinrich won the Henry David Thoreau Prize for literary excellence in nature writing in 2018.

In his most urgent book to date, world-renowned biologist Edward O. Wilson states that in order to stave off the mass extinction of species, including our own, we must move swiftly to preserve the biodiversity of our planet. He argues that the situation facing us is too large to be solved piecemeal, and he proposes a solution comensurate with the magnitude of the problem: dedicate fully half the surface of the Earth to nature. Identifying actual regions of the planet that can still be reclaimed, Wilson puts aside the prevailing pessimism of our times. Edward O. Wilson won the Henry David Thoreau Prize for literary excellence in nature writing in 2011.
