The latest news on our wildlife with Su Ingle and Michael Jordan Friday evening at Bristol railway station. Hundreds of rail travellers. But in a moment they're going to be joined by tens of thousands of very different commuters. Starlings! What are they doing there? Mike has the answer to why so many of our cities have large starling roosts. And Su meets three schoolchildren who come to the Wildtrack studio to receive their awards as Young Birdwatchers of the Year. Producer MIKE BEYNON. BBC Bristol
