I purchased one of your wire-bird feeders in Feb and want you to know that it's what a wonderful feeder it is. This morning I watched a small brown bear tearing up my feeders and when he came to your wire feeder that is on a pulley in the tree he tried to pull the rope and then grabbed hold of the feeder and was swinging in mid air on it. After not being able to tear it apart he left it alone. The wire feeder has no bad damage,I can tell you my other feeder are ruined. I was wondering if you had smaller wire-feeder to hold the thistle seed, something that would work for the Pine Siskin's and Golden Finche's. If so the cost.
