The RSPB's newest reserve - Saltholme, near Middlesborough - is now open. It is set amid the chimneys and factories of the industrial north east of England on the site of Victorian salt wells and is protected as a site of special scientific interest. In this episode of Nature's Voice we go along to find out what makes it so special and talk to Kate Humble, RSPB vice president and digger driver extraordinaire, about digging the first hole there! We also have tips about choosing and siting a nestbox to encourage our garden birds into our gardens.
