Loading... Please wait...One of the first things you notice when you start feeding the birds suet, is that you'll have some birds you don't want, mostly non-clinging birds like sparrows, starlings and grackle, all coming in to clean out your suet feeder. The upside down suet feeder helps keep them away, by not allowing non-clinging birds to eat. Clinging birds like nut hatch, titmice, and woodpeckers will easily be able to sit on the bottom of the Upside Down suet feeder and enjoy the suet, while others won't. This suet feeder holds two standard suet cakes, stacked on top of each other, so you won't have to refill your suet feeder as often, which will allow you to spend more time watching and enjoying the birds and less time filling up the feeders!
