We try to discourage the raccoons from getting too close cuz they also run raids on our nectar feeders. They're not very good at stealing nectar, either--picture a sticky, wet raccoon on a sugar high and you'll see why we discourage them coming around!
Plus our sugar and sunflower bills are already pretty high.
We finally solved the nectar problem by hanging the hummingbird feeders for morning under
our raised deck out of reach of the raccoons but easy for the hummers to find. And once the sweets were out of reach, the coons pretty much abandoned us for good stuff (like berries, I suppose) they can find out in the wild.
