Have you seen a hen harrier? These beautiful birds of prey breed in upland areas, but in England, none were successful last year, and this year only three pairs have bred.
There's enough habitat for 300 pairs - something is very wrong, and there's compelling evidence that it's persecution which is stopping the hen harrier's recovery in England.
We're raising money for hen harrier conservation. With help from you and the EU LIFE+ fund, we'll be able to follow harriers with satellite technology, call for stronger laws, and demonstrate that harriers and grouse moors can go together. We're also working to win the hearts and minds of the next generation, with our Skydancer schools project.
And this Sunday, 10 August, is Hen Harrier Day, and people will be gathering to show their support for these birds, calling for action.
