Bill Oddie's How to Watch Wildlife S02 E07 A Dorset River

Bill explores the delights of Dorset's River Frome in autumn and uncovers what could be the real inspiration for Ratty in Wind in the Willows, one of his favourite books. He also reveals the enigma of the mute swan and grapples with native crayfish before ending his journey with avocets and little egrets at the river's mouth in Poole.
