Anyone who puts up a birdfeeder hoping to to enjoy the birds will soon attract unwanted guests - squirrels. These cute but rapacious little monsters chase off the birds, eat all the seeds, and can chew birdfeeders to bits.
I've been trying to fight off squirrels since 1989, when I put my birdfeeder webcam, SeattleBirdCam.com
, online. I tried ultrasound generators, slingshots, and spiking the birdseed with hot peppers - all to no avail. After studying a number of expensive "squirrel-proof" birdfeeder designs on the market, I came up with my own inexpensive patent-pending birdfeeder design which can use cable ties (tie wraps) as flexible plastic perches. These "Flexi-Perches" (tm), combined with PVC pipe of the right length and width, make an inexpensive, easy-to-build, and effective squirrel-proof birdfeeder.
