Help! How can we feed the birds and not the squirrels?

We have a bird table which is now a haven for squirrels. As your recent letter printed, we too are inundated with these pests.

They dig out my plants and bulbs, have 'fun' on my tubs and charge up and down the 'greased pole' etc.

To say they are acrobats is an understatement.

Please someone help!
