Many people have issues with keeping larger birds off of their feeders. The Duncraft Satellite Feeder has been designed to deal with this problem. It is small, without a perch (perfect for birds that "cling") and spins when larger birds try to land on it. Best of all, the Satellite Feeder is pretty inexpensive. You might want to give it a try if you are tired of Crows and Band-tailed Pigeons emptying your feeder in a matter of minutes!
