Squirrel Proof Caged Feeders provide the best of both worlds; protection from unwanted creatures like squirrels and larger birds, and protection from the elements. Small songbirds easily fly in for safe feeding. The 10.5 in. diameter black metal cage encases a 15 in. green tubular sunflower or mixed seed feeder. The 1.5 in. cage openings allow small songbirds easy access to the bird feeder while keeping out large birds and squirrels. The 15 in. clear polycarbonate dome shelters against the elements. The enclosed feeder is easy to remove for cleaning. Backed by Droll Yankees Lifetime Warranty Against Squirrel Damage.
