Natural World - Season 35 Episode 8

Running through the heart of Ireland, the Shannon is the longest river in the British Isles. For locally born naturalist and cameraman Colin Stafford-Johnson, it is also the wildest. Amongst the river's cast are kingfishers and predatory pike, and living on its banks are native red squirrels. On a seasonal journey in his faithful canoe, Colin paddles along the Shannon to reveal its wild treasures.
