I'm sure this question has been asked a billion times, but...how to discourage blackbirds and starlings at my feeders? They were guzzling down big chunks from my suet holder, so I attached the holder to the bottom of a 6x6 piece of plywood and hung the platform on my feeding station. Woodpeckers can get to it easily. At first, this stumped the black birds, but being the smart birds they are, they've now figured out how to fly from beneath, hang onto the suet holder, and eat the suet. So my adaptation has slowed them down but not stopped them by any means! I've thought about buying a suet feeder within a cage. Will these keep black birds and starling out but allow access for larger woodpeckers like the red-bellied and flickers? Any specific feeders recommended? BTW, I'm located in eastern N.C.
