@skipt07 I do have one squirrel proof feeder but some of my birds prefer a flat type feeder so I still have a couple of those that I put out. The squirrels get some, but the birds manage to get a few too. Mine is a different design than the one you linked but works well too. Pictured here ( well part of it is pictured).
