Introducing the patented, Underneath Bird Feederâ„¢ The Underneath Bird Feederâ„¢ is unlike any bird feeder you’ve ever owned. It delivers black oil sunflower seeds or sunflower hearts from underneath the tube! This unique concept, combined with durable construction takes all of the bother out of feeding the birds! –Squirrel proof! Squirrels can’t reach down this long tube to get the seeds underneath and they can’t hold onto the small, vertical perch below. And a squirrel lock keeps the top locked down tight. –Big bird proof! Large, heavy birds such as starlings, grackles and blue jays can’t cling to the vertical perch. You’ll enjoy only the smaller songbirds as they land on the perch, pluck a seed from under the feeder and fly off—one after another! –Weatherproof! When other feeders are clogged with ice and snow or soaked with rain, the Underneath Bird Feeder keeps delivering fresh, dry seeds. Seeds are never exposed to the elements—no more moldy seed! –No waste! Birds pick out one seed at a time. Less seed falls to the ground. Large capacity tube lets you “fill it and forget it.â€? –Hygienic! Bird droppings never come in contact with the seed. And less seed falls to the ground, keeping your feeding area clean. Recycled plastic makes cleaning easy—just hose it down with the garden hose. –Durable! Constructed of recycled plastic that never fades, cracks, warps or weathers. Stays beautiful and lasts a lifetime! For use with black oil sunflower seeds only. Brown, recycled plastic with a wood-grain finish. Holds about 5-1/2 pounds of seed. Dimensions are 4 x 4 x 20 inches tall. Patent #6,843.204
