When making a finch feeder, it is important to make your feeder accessible to finches while keeping other birds from devouring all of the thistle seed inside. Thistle, also known as niger (or nyger) seed, is a very small, oily black seed. This is the preferred food of colorful finches. It is expensive, hence the need to keep it in the best possible shape and limit access to the seed to only the birds you hope to attract.
Goldfinch also enjoy sunflower seeds, which can be offered from any almost any feeder. Special instructions are only necessary if you hope to encourage certain finch varieties and discourage other birds.
