“Reveals the strange and wondrous adaptations birds rely on to get by.” —National Audubon Society When we see a bird flying from branch to branch happily chirping, it is easy to imagine they lead a simple life of freedom, flight, and feathers. What we don’t see is the arduous, life-threatening challenges they face at every moment. Beaks, Bones, and Bird Songs guides the reader through the myriad, and often almost miraculous, things that birds do every day to merely stay alive. Like the goldfinch, which manages extreme weather changes by doubling the density of its plumage in winter. Or urban birds, which navigate traffic through a keen understanding of posted speed limits. In engaging and accessible prose, Roger Lederer shares how and why birds use their sensory abilities to see ultraviolet, find food without seeing it, fly thousands of miles without stopping, change their songs in noisy cities, navigate by smell, and much more.

Unlike any other group of organisms, birds have official common English names and by custom, the names are capitalized. So we have the American Robin, Oak Titmouse, Northern Mockingbird, and Downy Woodpecker. The local jay is often mistakenly called a blue jay, but even though it is blue and is a jay, it is a Western Scrub Jay. The real Blue Jay lives mostly east of the Mississippi River. Author Roger Lederer and illustrator Carol Burr identify these characteristics for birdwatchers visiting Bidwell Park in Chico to observe over 100 species living there.
