In a cold winter, there's a real danger of garden birds dying in millions. So it's particularly important to put out food. If you don't have a bird table, how about building one?

Tony gives some tips of his own, but invites you to submit your designs for the perfect bird table to: Wildtrack, BBC Bristol, [Postcode removed].
