Best Bird Feeders How Can I Attract Gold Finches To My Bird Feeders?

How can I attract gold finches to my bird feeders? - best bird feeders

I have several bird feeders in my garden. Some contain sunflower seeds, and some contain a mixture of wild birds, and two of them contain Canada thistle (which are long, thin cylinder type).
Many birds come to my feeder, but very rarely seen gold finches.
What should I bring?
Thank you!
