With a two-way mirror on the back, this feeder lets you observe your feathered friends without disturbing them. Birds enter through the holes in the ends and feed inside, out of the weather and safe from predators. Holds 2 cups of seed; top flips open for easy filling. Mounts on window with suction cups; perforated stainless steel floor for drainage. Handcrafted in Maine from white pine; weathers to a silvery gray.
