A Harrisburg birder called my feeder setup "a squirrel buffet" and I redid everything that weekend
I was at a native plant sale in Harrisburg last Saturday when a woman named Deb pointed at the photo on my phone and laughed, saying my tray feeder hung way too low off the pole. She walked me through her own setup: baffle at 5 feet, feeder at 8, and nothing within 10 feet to jump from. Two weeks in and the squirrel visits went from 15 a day to zero, plus the cardinals finally stick around instead of grabbing one seed and bolting. What heights are you all running on your poles?
Wait, you had 15 squirrel visits a day? That is way more than I would have guessed for one feeder, and I would have given up long before Deb showed up. My pole setup sounds a lot like your old one, so it looks like I have some measuring to do this weekend.
