In this book, paleontologist Eldredge, author of Life Pulse and other books dealing with evolution and the history of life, notes that the decline of migrating songbirds may likewise signal catastrophe, but on a global scale.
He reviews the evidence for extinction and its causes, primarily using fossil evidence and focusing on climatic change and loss of habitat.
This book is aimed at the same interested lay readers as David Raup's Extinction, but differs in its focus and its more wide-ranging discussion.
If forced to choose between the two, pick this one.- Joseph Hannibal, Cleveland Museum of Natural History
