Zoo tries to save world's rarest Magpie
Rare bird experts at a zoo in Cheshire have started a project that they hope will save one of the world's most endangered birds.
The Javan green Magpie from Indonesia has been poached almost to extinction.
Now, four pairs of the birds have been brought to the UK in the hope that they will breed.
Andrew Owen, who looks after the birds at Chester Zoo, hopes the project will stop these types of birds from dying out.
