Photoflashing Western Owls (0 National Geographic Society Kodachrome by Lewis W. Walker Sitting on Its Snack Bar, an Elf Owl Feasts on a Grasshopper No bigger than a sparrow, the Elf Owl snatches nectar-hunting insects as they are attracted to the yellow blossoms of a century plant. This smallest of North American owls nests in a giant saguaro in the Kofa Moun tains, Arizona (Plate II). The tiny night flyer, in contrast to his bigger cousins of silent flight, wings through the blackness with a noisy swish. It feeds almost exclusively on ants, beetles, and grasshoppers.
