I couldn't possibly begin to feed the squirrels sufficiently to keep them out of the birdfeeders.

I wish they liked acorns half as much as they like sunflower seeds. My yard is full of mast. Last weekend I looked out one of my front windows and out of curiosity, counted 20 squirrels in my field of vision without turning my head.

I have 3 different designs of springed feeders that I fill with sunflower seed that work just fine to keep the squirrels out - I had to put a squirrel baffle on the top of one they had figured out how to detach the feeder from the hanging apparatus (and it wasn't easy!) dumping the feeder on the ground to spill the seed. Before adding the squirrel baffle I tried wiring it.   The peanut/nugget feeders and suet feeders are more difficult. There is only one spot in the yard where a squirrel might not be able to spring onto a peanut feeder from an adjacent tree - baffles don't help with horizontal leaps from tree trunks - but that is one of the few spots in my yard where I also would not be able to see the feeder from the house.

In addition to the sunflower feeders, I have a nyjer feeder, 3 standard suet cake feeders, one caged suet feeder and a hummingbird feeder, not currently in use. I also keep a bag of mixed birdseed that is mostly millet on hand and broadcast it when snow is on the ground for the sparrows.

I did have a couple of suction-cup feeders attached to a front window, but they kept falling off, and I also noticed a higher rate of birds slamming into the windows (not to mention bird crap on the house and windows,) so no longer use them. Besides, I had a hard time getting inside chores done with the opportune distraction of birds so close for observation.
