Secret Squirrels?

Love them or hate them, you can't deny that squirrels are very clever little creatures.

I fill up the bird feeders with nuts, only to find that as soon as my back is turned they decend like locusts upon them before the birds get a look in! They even get into the 'squirrel-proof' feeder!
But hey, if they can drink beer with a straw they must be ok, and can come into my garden anytime they like!
