Perhaps, but only if you define the "issue" as squirrels getting bored because the feeder is too easy to get into. My favorite in this vein was a metal sleeve on the pole holding the bird feeder that was held up by a weight inside the pole. Squirrel climbs up sleeve, which then falls down due to the squirrel's added weight. Disappointed squirrel deposited back on the ground. It worked until one of the squirrels chewed a hole in the pole and ate through the cord holding the weight. This really happened on a bird feeder belonging to a friend's parents. (Related question: how on earth did the squirrel figure that out?)
