I concur, “The Ascent of Birds” is a remarkable resource for understanding how the bird world fits together, post the great genome crunch of recent years. As the lead writer for BirdNote, it has also been a rich source for radio stories.

While you are hanging out close to home, here’s a timely book: “Nature’s Best Hope: A New Approach to Conservation that Starts in Your Yard” (by Douglas W. Tallamy).

Good reading, Bob Sundstrom

> Two years ago I read “The Ascent of Birds” by John Reilly (2018), an exploration of many intriguing questions about birds, with emphasis on recent advances in understanding of bird ecology, biogeography, evolution, physiology, and behavior. In 27 chapters averaging about 10 pages/chapter, Reilly introduces a bird species (hoatzin, oilbird, godwit) or group (tinamous, waterfowl, hummingbirds, storm petrels, owls, parrots, manakins, crows, thrushes, sparrows, crossbills, tanagers, and many more). Each chapter is "a pithy essay describing some special features" of the species or group. The role of geologic and biogeographic events in evolution of each group is coupled with special features such as morphological, physiological, and behavioral adaptations and, when known, their genetic underpinnings. For example, how do Bar-headed Geese fly over the Himalayan Mountains or Bar-tailed Godwits fly non-stop from Alaska to New Zealand (more than 7,000 miles) in 9 days? What ecological and biogeographic factors underpin the extraordinary diversification of hummingbirds in South America? How does hummingbird metabolism sustain a heart that beats 1200 times per minute during flight? How do albatrosses find enough food to sustain themselves and their nestlings in apparently featureless expanses (up to 5.9 million square miles) of open ocean? Why are falcons closer to parrots than hawks in recent field guides? And so on.

Some of the concepts are a little challenging but the book includes a comprehensive glossary, list of sources for each chapter, and a comprehensive index. He shows how geography, ecology, and lots of time answer the question ”How did the incredible diversity of more than 10,000 living bird species come to be?”

Since developing an interest in avian evolution, he has concentrated on tracking down and photographing species that have important evolutionary studies to tell. And he tells those stories very well.
