This week, Animal Magic goes 'bats'. Bats live in ruins and roofs, emerging at night to By through the dark in search of food. Animal Magic investigates how most bats use an extraordinary radar system to find their way in pitch blackness.
And we give you instructions for building a bat nesting-box - so you can encourage bats to live in your own back garden.
