I have a quandary which may be unsolvable, but I thought I would ask to see how others have dealt with this problem: I want to feed cardinals, who only feed on the ground out of sight right now because all of my feeders cater to smaller birds.

I know that if I were to put out a platform feeder house sparrows would be attracted and I don't want that.

Would a fly-through feeder be a safer bet?
