Tragedy as extremely rare bird spotted in England, then killed by wind turbine

Wind turbines can be a great source for renewable energy, but it's hard to ignore the threat they pose to birds. The white-throated needletail is the fastest flying bird in the world. It's also one of the rarest. Until this week, it hadn't been seen in Britain since 1991. When one turned up on the Isle of Harris, people from all over the country came to see it. Some were able to get a glimpse of the beautiful bird before it flew right into a wind turbine and died instantly. The corpse is being sent to a museum, but as wildlife expert Steve Duffield said, it's still "a very sad end to a delightful bird."
