RollerFeeder’s “self-contained” design means that you can hang it right from a tree limb or horizontal extension. It does not require additional guards, special poles, or any other squirrel deterrent devices to operate. R-Feeder also does not allow large unwanted birds to land and feed.
The built-in design allows complete access to the feeder and welcomes all typical problem animals and birds. It is when the animal or large bird commit themselves and climb, land, or jump on the feeder is when they are suddenly taken by surprise.
