Hopper Feeders are one of the top choices when it comes to protecting bird feed from the weather and unwanted pests (like squirrels). With Hopper Feeders, all the bird feed is held in an enclosed figure and the feed can only be accessed from feeding ports near the bottom perch. The design decreases the chances of wet bird feed and squirrel raids. This is especially true if you purchase a Hopper Feeder with a weight sensing perch – which (as the names implies) will close access to the bottom feeding ports if touched by anything weighing more than your average songbird. Hopper Feeders are available in a wide range of sizes but many of them are quite large and can hold seeds for multiple days. Owning a feeder that you know will protect bird feed and one that doesn’t need to be refilled everyday can be a major convivence and a great benefit to the birds.
