The "twirl-a-squirrel" feeders are not only quite entertaining for us humans
, but rather effective as well!!!
Being in an area that is heavily invested with squirrels, here's the solution I eventually came up with. I selected a place in the yard that is at least 15 feet from the nearest structure or tree or branch or... you get the idea. There is nothing above it, either.
I planted a 12-foot section of gas pipe about 2 feet into the ground, and poured a 10-inch "dish" of concrete around it for security/stability. On the top I placed a flat "platform" on which to scatter seeds and unshelled roasted peanuts. I added two 2-foot "arms" just below that, and hung two finch feeders on them.
The squirrels cannot climb the gas pipe, and they cannot jump that high. There are no nearby "launching pads" from which to jump or dive. Not that they haven't been trying, of course. I do need a step-stool to reach the top platform, but what the hey?
Lately I've heard rumors about about secret squirrel-meetings to identify and plan ways to get even with me, but so far nothing of interest has occurred!
