This past Christmas, Kara and Adam got me a bird feeder that looks like a giant cattail. It's great for filling with sunflower seeds and I did just that, so the cardinals would have a fashionable dining area. I mean, they are pretty flashy and being our state bird, they deserve it! That's not really why I wanted it, but it is one of the more attractive feeders available.
The cardinals haven't found it yet, but the sparrows have!
