Do you ever see a hen harrier in the Netherlands? Then you are very fortunate! These beautiful birds are having a very difficult time surviving in this country. They are only found in just a few places and their numbers keep dropping. It is unknown why this is happening, but is probably due to a lack of food and a decline in their breeding grounds. Just like the marsh harrier, hen harriers have a shallow V-shaped sillouette as they scan the ground for prey or glide low over the ground.
