Book excerpt: An “entertaining” history and illustrated guide to seventy-six kinds of sparrows: “You will not find more complete or better written accounts of these birds.” —Minneapolis Star Tribune What, exactly, is a sparrow? All birders (and many non-birders) have essentially the same mental image of a pelican, a duck, or a flamingo, and a guide dedicated to waxwings or kingfishers would need nothing more than a sketch and a single sentence to satisfactorily identify its subject. Sparrows are harder to pin down. This book covers one family—Passerellidae—which includes towhees and juncos, and 76 members of the sparrow clan. Birds have a human history, too, beginning with their significance to native cultures and continuing through their discovery by science, their taxonomic fortunes and misfortunes, and their prospects for survival in a world with ever less space for wild creatures. This book includes not just facts and measurements, but stories—of how birds got their names and how they were discovered, and of their entanglement with our own species.
