I'm sure this has been asked before, but I need some advice on buying a bird feeder. I want one that will feed most backyard birds, including cardinals that like to perch as they eat. I need one that squirrels can't get to the feed, but birds can...I've seen some feeders that small birds can use (finches, etc.), but not others like cardinals. We bought a "squirrel proof" feeder at Walmart a year or two ago, and here is a picture of it.
We buy the wild bird feed that has mixed seeds and the squirrels like to dig it out, pouring it all on the ground as they look for certain ones (I assume sunflowers). Anyway, please let me know if anyone has a feeder to recommend. Thanks.
