Sy Montgomery Quote
Voles make up 85 percent of the diet. (One feature of vole biology that inadvertently helps out hawks is that these rodents mark their territories with urine, which Scandinavian researchers recently discovered reflects ultraviolet light. Hawks can see UV light—and may well use the voles’ territorial markings as signposts to the nearest restaurant.)
