Here is a YouTube link to the video commissioned by WWF, RSPB and NT as an extra to their five part series formed with OU, and shown on BBC. I believe this is the 'episode' that ccan be viewed via iPlayer. This short circuits the need to use iPlayer. It is on the RSPB website on the Save Our Wild Isles page.
