Last week, our resident squirrels discovered that Jeanine’s recipe for hummingbird food makes for a mighty tasty afternoon aperitif. After some trial and error, she fashioned a couple of aluminum pie tins into an effective squirrel barrier. Unfortunately, with the slightest wind, it also worked as an effective hummingbird deterrent. Today, I installed a more conventional solution, but it remains to be seen if this “tippy” dome will do the job.
