I have been into bird feeding for a long time, but want to get a feeder especially for Cardinals. I currently have the Droll Yankee tube feeders that I use for black oil sunflower seed and one for Niger thistle. I also have suet feeders for the woodpeckers. I have been looking at the Droll Yankee hanging feeder that has a dome for the Cardinals, as well as the platform feeders with a dome cover. I believe both of these have holes or screening for drainage. Any experience with either of these types of feeders and things I should look for/be aware of or are there other Cardinal feeders that you prefer?
