I love goldfinches too. We took our sunflower feeder down for the summer as the blackbirds are pigging out on the seeds so the goldfinches are temporarily eating in someone else's yard. They'll be back as soon as my purple coneflowers go to seed though.
No matter how often I see them, when they come to our feeder, a song breaks out in my soul and at that moment I am filled with complete happiness. Peace
