These thistle/nyjer sacks are sure to  attract many birds including Pine Siskins, Redpolls, House Finches, but most especially goldfinches. Goldfinches are attracted to the colors of black and yellow so when these socks are filled with black nyjer, they are especially attractive to those species. These socks are also economical alternatives to expensive metal feeders.
 
 The draw string at the top helps to make sure that if your Nyjer sock is knocked down in a storm or high winds you don't loose that precious Nyjer seed like other feeders. The Nyjer sock is made of nylon ensuring you a long life and a full yard of birds for many years to come.
