After watching the fantastic Bear Walker of the Northwood episode of the Natural World series (catch it on iPlayer
here) I thought I'd look Prof Lynn Rogers up, and was very glad to see lots of his papers published and available on his website:
Publications
I heard an interview with him on Radio 4, watched the documentary and am very impressed with this chap. He's expanded what people know about these fantastic animals by a significant margin. Lovely chap too, as well as his wife. Very brave, and more power to 'em for what they're doing. They deserve a lot more recognition, the world needs people like this in my opinion.
