The Yankee Whipper features four collapsible mechanical perch rods that are weight activated using a patented design. The curved perches attract a wide variety of birds including cardinals, but the weight of a squirrel will cause the perches to collapse. The perch resets automatically after the squirrel slips off.
A 21-inch long feed tube can hold 5 pounds of seed. Its sturdy stainless steel wire hanger will not rust. The metal cap fits snugly so that squirrels cannot pry it off.
This feeder has a 4.75-inch diameter seed tube made of a durable UV stabilized polycarbonate and is long enough so that squirrels cannot hang down from the top and reach the seed. Its interior is properly baffled to direct seed to the seed ports. Four seed ports are positioned below the tube.
Metal parts have a beautiful evening blue finish. This bird feeder measures 21 inches in length with a diameter of 4.75 inches.
