This is a compact caged feeder designed to prevent persistent squirrels from gaining access to bird seed. It is an 11-1/2" high feeder that meets this design. Squirrel paws simply cannot reach the seed! Small birds, however, are able to easily pass through the Havenguard fencing and feed at the four feeding ports. They also perch all over the wire -- for lots of watching enjoyment! The open-wire base prevents spilled seed from accumulating, and that discourages squirrels from hanging on to feed.
