Our Satellite is designed to attract chickadees, nuthatches, titmice and
finches. One at a time a bird land, picks out a fat sunflower seed and then
dashes off. A lot of folks find this feeder great fun to watch, as birds return
again and again, and set the Satellite spinning! The clear see-through top lets
you check seed levels easily. Pigeon-proof and starling-proof. 6 inch diameter,
complete with hanging chain.
