From tiniest hummingbirds to condors with nine-foot wingspans; from lower-elevation wrens to the rasping nutcrackers of the High Sierra; from urban House Sparrows to wild water-loving American Dippers, Hansen's Field Guide to the Birds of the Sierra Nevada showcases artist-naturalist Keith Hansen's sixteen-year project to illustrate the birds of the Sierra Nevada. Paired with stunningly detailed portraits is text informed by decades of birding experience-prose that while firmly grounded in expertise will nonetheless delight readers with its whimsy, allusion, and affection. Take the Bufflehead: "A diminutive and endearing diving duck," which moves "with spirited abandon." Or, the "scrappy and antagonistic" Merlin, "holding dominion over winter skies, tormenting eagles, hawks, and vultures alike." The White-tailed Kite is "angelic in poise, a streamlined bird of unblemished tailoring"; the Blue-gray Gnatcatcher sports a black eye-to-eye brow, imparting a "Frida Kahlo-like stare."
