Well, they can be destructive and I have a few half-chewed bird feeders to prove it. :D But I still love the little critters. I find if they can easily (and I do mean easily!) get to the birdseed in the feeders, they just eat and leave the feeder alone. They are voracious eaters, but we enjoy them so much, it's okay with us. :D :D
It's nice to meet some folks who enjoy them also. I understand why some try to discourage them from getting to their feeders, but we have learned to enjoy and embrace them and their funny little antics. :D
