It has worked so well I had to share the footage I've collected!! There's a few things I've changed to make it even better, but the original main design has not changed at all and has performed beyond expectations! We've had about 7 or 8 squirrels show up (and that's only what we've seen) and climb the pole and get on top of the squirrel proof bird feeder to only check every square inch of it and leave dejected!! They cannot get into it or even get a single seed out of it, it works that well!! They are not even able to chew any part of it and damage anything. It is attracting more and more different species of birds every day and has become a source of entertainment watching the birds come to feed with others and leave.
I used my new GoPro Session camera. I was able to put it inside the squirrel proof bird feeder to get some great shots of the birds coming and going.
P.S. It turns out the ABS pipe perch only worked for a few weeks then fell off. Each time a bird landed on it, it moved a bit and eventually walked its way off. The solution has been to cut a length wise groove in a piece of 3/4" x 3/4" pine and adhere it to the edge of the glass with silicone. It's now been in place for 3 years.
