Goldfinches and friends?

This winter my nyjer feeder has been inundated with American Goldfinches. They come in droves, filling the perches on my feeder and emptying the seed! I don't mind, trust me. I love watching them and providing a suppliment to their winter diet, however, they have refused to bring their other finchy friends. This has been a really good year for Pine Siskins and there are numerous Common Redpoll reports as well, but alas, not at my house. Well, winter's not over yet!
