This video is called Short-eared Owl -Asio flammeus.
According to a report by BirdLife in the Netherlands, this year six or seven short-eared owl couples have nested on Schiermonnikoog island. About ten tears ago, just one couple of these owls used to nest there.
Unfortunately, in the Netherlands as a whole, things are not going so well. Just 10-30 couples are left from what used to be many more.
