These are excellent bird feeders with the added benefit of being squirrel proof. Openings in the feeders align with ports, giving birds access to the feed inside. When a squirrel climbs onto the feeder, its weight forces a shroud down, making the feed ports inaccessible. Squirrels are foiled but not harmed in any way.
The 3/4-quart Nut feeder is 18" tall and holds shelled peanuts or similarly sized suet pellets and dried fruit, allowing you to establish a separate feeding area for species such as woodpeckers, jays and nuthatches. It has a wire-mesh shroud with five large openings. The internal seed hopper is also wire mesh to let birds peck at the contents without allowing whole nuts to spill out.
The two models of songbird feeders are suitable for sunflower-seed mix. The 1.4 quart Classic songbird feeder is 19 1/2" tall, with four large ports and perches, plus a wire-mesh shroud that gives perchers and clingers ample room to feed. The larger 3-quart Plus songbird feeder is 23" tall, with six length-adjustable perches and a ring perch to accommodate cardinals.
The Peanut and Plus models have a weight threshold that can be adjusted to keep out heavier birds. All feeders are corrosion resistant, UV stable and easy to clean. Instructions included.
For mounting a Squirrel Buster Plus feeder where there is no overhead support for hanging, an adapter is available separately.
Note: The feeders are effective against black squirrels. Immature red squirrels can sometimes gain access due to their size.
