21/30 The Bar-Headed Goose, according to research biologist Lucy Hawkes, "is at the limit of what a goose can do". Lucy Hawkes, from Bangor University, studies this remarkable bird on its breeding grounds in Outer Mongolia on the grassy plateaus. Her work has largely been concerned with how they get back and forth to their breeding grounds from their south Indian wintering areas. But how does studying the migration of the Bar-Headed Goose help inform their conservation. Lucy, recently back from the field in the Himalayas is in the Saving Species studio.

Also in the programme: The re-intruduction of the Fen Raft Spider into a restored marshland in Suffolk. Chris Sperring went to see the spiderlings "lowering themselves from their test tube [home] by a thread" into the wild. A wonderful story of animal husbandry, habitat restoration and the science of re-introduction.

And where has Chris the Cuckoo ended up, or is he still heading south. We'll have the BTO live in the programme to bring us up to date with the Cuckoos on the move.
