17/30 Butterfly expert Matthew Oates is tramping the wilds with Brett looking for the Purple Hairstreak Butterfly. And Julian Hector reports from the North Slope of Alaska where he meets the team working on the extraordinary Spectacled Eider. We also hear from Sarah Pitt who has been looking for Water Voles - so this weeks edition of Saving Species is truly outdoors.
Look below for the pictures of the Spectacled Eider and the link to the U.S Geological Surveys website, where you can follow the latest news of the Spectacled Eiders being studied.
