Big aviation news this week: the red-necked phalarope is one of Scotland's rarest breeding birds and was thought to migrate to its winter grounds in the Arabian Sea. This past week, it was reported that a new tiny tracking device reveals that the phalarope actually flies across the Atlantic Ocean down to the Caribbean, all the way to South America. So, is the phalarope a Scottish bird or a South American one? Malcie Smith is from the Royal Society for the Protection of Birds and he joins us from Scotland. Thanks very much for being with us.
