This bird feeder is one of the best for keeping the bird seed dry. The clear acrylic is completely weather proof and lets you easily see the seed level. Rain and snow can not get to the seed, so it stays dry and mold free. When it is time to clean this bird feeder it comes completely apart so it is very easy to clean. That is the feature I really like about this bird feeder because a clean feeder and dry seed will keep my wild birds healthy! This bird feeder is fun to watch, the birds sit on the lower platform and feed by reaching up and pulling the seeds through the slots in the bottom of the hopper. Since it is made of clear acrylic birds on the far side are even visible. (via Good Bird Feeders)
