"The first major work in sixty years about the most famous extinct species since the dodo.equal parts natural history, elegy, and environmental outcry . A painstaking researcher, Greenberg writes with a naturalist's curiosity about the birds . Answering even basic questions about the passenger pigeon requires a sort of forensic ornithology, which gives Feathered River Across the Sky an unexpected poignancy at the very points where it is most nature-nerdy." - New Yorker   "Joel Greenberg has done prodigious research into the literature of the passenger pigeon and lays much of it out in this book. For that effort, all who care about the living world owe him a debt of gratitude." - Wall Street Journal   "A brilliant, important, haunting and poignant book, A Feathered River Across the Sky .  will forever change the way in which you think of pigeons (all birds, really) and about the natural world.

The book describes, in vivid detail, forceful narrative and handsome illustrations, the history of this species and the factors that contributed to its extinction." - Chicago Tribune   "Joel Greenberg, a Chicago-area naturalist and avid birder, has written a new account of the passenger pigeon's demise, A Feathered River Across the Sky . As Greenberg relates it, in calm, measured prose, it's a story of unremitting, wanton, continental-scale destruction." - New York Review of Books "Thoroughly researched and well written." -Edward O. Wilson, University Research Professor Emeritus, Harvard University " A Feathered River Across the Sky is a parable for our time . What a heartbreaking indictment of our species that we treated these animals so thoughtlessly." -David Suzuki, author of The Sacred Balance "The human folly depicted here is as deep as the pigeons were numerous .

Highly recommended."  - Library Journal , starred review.
