Happened to be in the car just before 2pm today and tuned in to Radio 4. There was an interesting article on Prairie Chickens in Kansas. Looks like it was first run back in 2011, but it was the first time I had heard it. You can listen to it at: http://www.bbc.co.uk/programmes/b0150p92
There appears to be three separate series, with a number of episodes. Hope that someone finds them of interest.
