Squirrels stole all the bird seed at our wooded site in Washington so I oiled the pole in an effort to keep them off the feeder. Their cartoon attempts at climbing and sliding down the pole were eventually rewarded when they scaled the pole, looped over the top and dropped onto the feeder. It was a one way journey however.
If you’re worried about squirrelly’s fate it was only about a four foot drop to the grass. It didn’t stop him climbing the pole again, and again, and again . . . .
