Haha! Don't think so, but I've heard some people sometimes put extra sugar in the nectar recipe, on the theory that it can help a little to prevent the nectar freezing. BTW, have you ever hear of drunk birds? Some of the fruit eating birds (like Cedar Waxwings) have been known to eat fermented fruits and act drunken...of course, some of the birds don't survive in those cases. The rule, would be "don't eat fermented fruit and fly".
