The Sky Cafe’s extra large, squirrel-baffling hood makes this feeder squirrel proof from above! When squirrels approach the Sky Cafe from above, it’s angled rim sends them slip-sliding off the feeder and prevents them from hanging down to reach the seed. After years of selling this feeder, we have yet to see one chew mark!The large, see-though hopper holds about 10 pounds of any seed or mix and the wide seed tray extends 2 inches out from the hopper—plenty of room for larger birds like cardinals and grosbeaks to perch and feed. Constructed of heavy duty, 1/8 inch thick plexiglas. Includes 24 inch hanging chain. 17 x 17 inches.
