Feeder cage

I got the feeder a couple of weeks ago.  It was supposed to keep out the heavier birds, but the starlings had no problem at all and were emptying the whole thing in minutes.  This cage arrived today - it seems promising so far.  A few little birds have ventured inside it, and the starlings and pigeons are completely excluded.  I was going to try the moon again tonight, but it's hiding in cloud.
