The Woodlink NATUBE20NB Audubon Tails Up Nyjer Thistle Finch Wild Bird Feeder is well-made, sturdy, and simple to fill. It comes with yellow plastic perches that are long enough to reach through each parallel hole, providing added comfort for the birds. The feeder is suitable for goldfinches as they feed upside down. The top of the feeder slides up and down, making it easier to refill the feeder. It is not recommended for nuthatches and chickadees. Customers have reported positive experiences with goldfinches using the feeder after a learning curve. However, some have complained that birds don't use the feeder or that the Nyjer seeds tend to leak through the feeding holes. The feeder needs to be kept clean to attract birds, and the Nyjer seeds require proper storage to prevent molding.
