Fill up one of our Nyjer Seed Feeders to attract the Finches in your area! These beautiful birds eat in social groups called Charms, and will cling to the mesh feeders. These thistle (nyjer) feeders have very tiny ports where the finches will slide the tiny seeds out of the feeder. In most regions, Finches feed from these feeders year round. Keep in mind that other seed blends will not work in feeders specifically made for Nyjer or thistle seed.
