Conservationists at Chester Zoo have started the first conservation breeding programme in Europe for one of the world's most endangered birds.

The Javan green magpie has been poached almost to extinction from its native Indonesian forests. Now, three pairs of the birds have been released into their outdoor aviaries for the first time.

BBC science reporter Victoria Gill was there to see the tropical birds get their first glimpse of the British weather, with the zoo's curator of birds Andrew Owen.
