Life's mysteries solved no. 99

This morning Mr. Beewatcher opens the front door and asks me, " What's all that stuff on top of the car ? It wasn't there yesterday ".
" Search me ",says I.
So the very same day I'm upstairs and I can hear a strange cracking sound.
This is what I saw through the open bathroom window,this little perisher helping himself to the fruit of the hornbeam trees beside the drive and dropping the casings onto the car underneath.
I don't usually take a camera into the bathroom. Maybe I should.
