For those of you interested in feeding the birds, I recommend that you watch for those giant suction cups intended for hanging wreaths and other heavy holiday decorations. They work quite well for holding birdseed bells, suet cages, etc. I found a palm-sized suction cup at Wal-Mart for $2 and used it to attach a birdseed bell to one of the kitchen windows. Today I got another one and attached it to the north window of my office. If it's still stuck tomorrow morning (I have terrible luck with suction cups; they usually fall off) then I'll hang a suet cage there.
