Squirrel pests!

Much as I love wildlife, I wish there weren't so many squirrels. As fast as I fill the peanut feeder, the flippin' furry tree rats are performing acrobatics on it and within a couple of hours, it's empty again and the poor birds haven't got a look in. And what's more, they've been burying their loot in the lawn. Wonder if we'll end up with a peanut plantation?
