The Perky Pet Squirrel Stumper bird feeder offers a variety of convenient features in one charming package. First, there is the twist lock lid, which not only removes for easy filling, but also locks in place so sneaky squirrels cannot easily open the feeder and steal seed from the top. This feeder also boasts a wire metal cage that creates a barrier around the seed reservoir making it harder for squirrels to gain access to the ports. Plus, the sturdy metal is designed to resist squirrel damage and chewing, as well as resist. The whopping eight feeding ports spaced evenly around the feeder provide plenty of room for multiple birds to dine at the same time. You will not have to worry about all those birds emptying your feeder too quickly during peak feeding times. When you do start to run low, the clear seed compartment makes it easy to monitor seed levels, so you know when it is time to clean and refill.
