I replaced my tube feeder with the fly through feeder. The birds were initially curious but cautious. After several hours they came to it. The feeder is very small so just House Finches and Lesser Goldfinches are eating from it. The feeder is easy to fill because of the movable lid. The color is ok, I would prefer it in a grey color rather than blue so as not to be quite so eye catching. The feeder is well made and easy to maintain.
