When we see a bird flying from branch to branch happily chirping, it is easy to imagine they lead a simple life of freedom, flight, and feathers. What we don't see is the arduous, life-threatening challenges they face at every moment. Beaks, Bones and Bird Songs guides the listener through the myriad, and often almost miraculous, things that birds do every day to merely stay alive. Like the goldfinch, which manages extreme weather changes by doubling the density of its plumage in winter.

Bernd Heinrich involves us in his quest to get inside the mind of the raven. But as animals can be spied on only 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.

In this New York Times best seller, a naturalist probes the forest to comprehend the secret lives of owls. Leigh Calvez takes listeners on an adventure into the world of owls: owl-watching, avian science, and the deep forest - often in the dead of night. These birds are a bit mysterious, and that's part of what makes them so fascinating.

From the cave walls at Lascaux to the last painting by Van Gogh, from the works of Shakespeare to those of Mark Twain, there is clear evidence that crows and ravens influence human culture. Yet this influence is not unidirectional, say the authors of this fascinating book: people profoundly influence crow culture, ecology, and evolution as well. John Marzluff and Tony Angell examine the often surprising ways that crows and humans interact. The authors contend that those interactions reflect a process of "cultural coevolution."
