Bird Brains ?

This is the view from the kitchen window and this is a box full of nuts to feed the red squirrels that visit the garden.

In the past I have watched poor confused birds trying to peck at the nuts through the glass front then flying away nursing sore beaks.

It now seems they have worked it out as some are now bravely going in through the small gap and darting in and out quickly to get a sneaky feed.

Not sure that the squirrels are as impressed as I am !
