Raging ambition. Towering egos. Competition under a veneer of courtesy. Heroic effort combined with plagiarism, theft, exaggeration, and fraud. This was the state of bird study in eastern North America during the early 1800s, as a handful of intrepid men raced to find the last few birds that were still unknown to science. The most famous name in the bird world was John James Audubon, who painted spectacular portraits of birds. But although his images were beautiful, creating art was not his main goal. Instead, he aimed to illustrate (and write about) as many different species as possible.

In Feather Trails, wildlife biologist and birder Sophie A. H. Osborn reveals how the harmful environmental choices we’ve made—including pesticide use, the introduction of invasive species, lead poisoning, and habitat destruction—have decimated Peregrine Falcons, Hawaiian Crows, and California Condors.

Called the Jane Goodall of wolves, world-renowned wildlife biologist Diane Boyd has spent four decades studying and advocating for wolves in the wilds of Montana near Glacier National Park. When she started in the 1970s, she was the only female biologist in the United States researching and radio-collaring wild wolves. With her two dogs for company, she faced the rigors of the Montana winter in an isolated cabin.

Birds. Over 9,000 species, the most widespread of all animals: on icebergs, in the Sahara or under the sea, at home in our gardens or flying for over a year at a time. Earthbound, we can only look and listen, enjoying their lightness, freedom and richness of plumage and song. David Attenborough has been watching and learning all his life. His classic book, now fully updated with the latest discoveries in ornithology, is a brilliant introduction to bird behaviours around the world: what they do and why they do it.

In What It's Like to Be a Bird, David Sibley answers the most frequently asked questions about the birds we see most often. This special brand-new audio edition is geared as much to nonbirders as it is to the out-and-out obsessed, covering more than 200 species. While its focus is on familiar backyard birds—blue jays, nuthatches, chickadees—it also examines certain species that can be fairly easily observed, such as the seashore-dwelling Atlantic puffin.
