Cambridge zoology museum to reopen

Sir David Attenborough to tour new premises that showcase the extinct moa bird's feathers

When Sir David Attenborough opens the University of Cambridge's zoology museum this week, the proud curators will show him their fabulous discovery.

It's fair to say the casual visitor might wonder why they are so excited by the scruffy frame containing a few cobwebby grey-brown wisps, discovered during a 4.1m redevelopment of the museum.
