Hey squirrel. Leave those nuts alone!

I recently put up a bird feeder to attract some more avian fauna into the garden. My feeder is supposed to be squirrel proof but unfortunately the local squirrel mafia don't seem to think so.

The other morning there they were, squeezed into the outer cage, frantically nibbling at the inner cage that contains the nuts. The pigeons were enjoying this spectacle and were hoovering up the nuts that were falling to the ground.

Yesterday I found the whole feeder empty and broken lying on the grass. The outer cage had been peeled away(probably the work of the Brockley Parakeets) and the inner mesh had been cut and opened out. I will need to repair the feeder before putting it up again and in the meantime the birds are going hungry :-(
