Something Goldfinches Do Like

I have made many efforts to attract finicky American Goldfinches (finicky and Goldfinch being synonyms, in my optinion.) And I am usually skunked. Special feeders? Nyjer socks? Naaaah! But possibly, just possibly I am on to one that does have some hope. Those Goldfinches---a mob of them---very quickly took to a new hanging platform stuffed with sunflower seed and have nearly lived in it during our winter storm days of Sunday and today. All the common wisdom says AG's are perching birds, but they seem -- around here -- to be lazier than that. I'm watching these little characters to see if I am on to something, or if like so many times before they hang around only so briefly and then court another.
