A Feathered River Across the Sky: The Passenger Pigeon's Flight to Extinction book by Joel Greenberg.

From Billions to None: The Passenger Pigeon's Flight to Extinction, reveals the compelling story of the unlikely extinction of the passenger pigeon and explores the pigeon's striking relevance to conservation issues today, such as the alarming depletion of shark species worldwide. For centuries, the sleek long-distance flyer was the most abundant bird in North America and perhaps the world. It was hunted to extinction in a matter of decades. On September 1, 1914, Martha, the last passenger pigeon in captivity, died in the Cincinnati Zoo, marking the end of the species, and the upcoming centenary of the extinction event.

"Compelling and cautionary...we get chilling history...filled with information and passion and does a remarkably good job of using computer-generated animation to show us what it must have been like to see a passenger pigeon flock."

But the tallgrass prairie and deep forests that once made up Chicago's landscape also inspired musings from residents and visitors alike. In Of Prairie, Woods, and Water, naturalist Joel Greenberg gathers these unique voices from the land to present an unexpected portrait of Chicago in this often charming, sometimes heart-wrenching anthology of nature writing.
