The secret for keeping squirrels off bird-feeders is rubber suction cups. You stick the seed troughs to a large window pane so the squirrel can gain no traction. When we first put ours up, an intrepid squirrel would dive from the roof beam and either miss or bounce off the feeder. After the squirrel experienced about a dozen bad trips it quit. It must have passed the word because none of its tribe have tried it.
However, we also tried hanging suet from a tree branch with monofilament. That was Cirque de Soleil.
