I like to feed the birds so I put a bird feeder on my deck (it’s out on a 3’ swing arm-keeps the mess off the deck). My house is on a hillside so if I put it on the ground I can’t see the birds.
The squirrels line up sometimes 6 deep for a chance to get the seeds. I shoo them off if I’m looking out the window and want to see the birds get some food. All in all a good enough arrangement.
After 2 years of this arrangement the squirrels have decided that they are unwilling to wait their turn and started chewing on the deck in an apparent effort to knock the feeder down. They chewed off a 1/4" by 5" section where the feeder is attached and have randomly chewed the railing in 10 other places. Now I have to repair the deck which I just re-stained.
