Eliminates Pest Bird Flocking

RollerFeeder prevents large amounts of birds from flocking directly on the feeder, leaving it completely open to more desirable chickadees, nuthatches and finches. It does it by just allowing access to the seed by small birds, and a small amount of weight. If pest birds can’t get to the seed, they will not flock on the feeder and move on to the next convenient food source. A common problem with feeding birds is overload by undesirable birds like starlings, blackbirds, grackles, and house sparrows. What can happen is the nuisance birds take over the feeder and keep the more desirable birds away. House sparrows are especially damaging to a feeder area because not only will they flock on open feeders (also known as a sparrow slum), they can also take over the the whole area and nesting sites of small birds like chickadees, nuthatches and finches. House sparrows and starlings are also very aggressive and can disrupt other native bird types in the area.
