I'm not sure who likes the new feeder more.....me or the finches! Usually I buy a sock feeder and when it is empty I throw it away....I have bought many in a season!!! This year TSC had this neat refillable feeder, and believe me I have to fill it at least every other day. They do love thistle. I love to watch the finches cover the feeder they are so beautiful. And then the fly up into the tree and make the sweetest little chirps.
