Sarah Darwin, the great-great granddaughter of British biologist Charles Darwin, was sleepless in Berlin when, to her "enormous surprise", she heard a nightingale warbling merrily outside her window.

"It's very, very rare in the UK, so to be living in the middle of a capital city in Europe and hearing a nightingale singing outside your bedroom window is quite an extraordinary experience," said the Berlin-based British botanist.
