I've never had a bird feeder in this type of design. It's more like a tray that the bird seed fits in and the birds have free range to eat. I was concerned that the bird seed would fall through the holes but it does not if you choose the correct type of bird seed to use with a bird feeder.

The design of the bird feeder was very creative. I in particularly enjoyed the fact that the hanging arms could expand and collapse. This will be great for when I need to put it away for storage during the off season.
