While we were busy cooing over them and handing out peanuts on the front porch, they were up to something of their own at the back...
The first thing we noticed was a suspicious amount of debris around the oak tree.
Odd - it hadn't been all that windy. A closer look showed empty acorn hats - much of the contents had disappeared.
The chipmunks were having a relay. One shinning up the oak tree to nip the twigs with their acorns and send them falling onto the grass, another coming down. "Go on Harry, it's your turn, bite those twigs son!"
And around the tree on the ground, the rest of the family were busy collecting the spoils.
Not content with tunneling our lawn into a swiss cheese, they're out to get the trees now. Little darlings.
