This is a very cooperative female that is raising his fledglings without the help of a mate. She is very tame and the photographers are feeding her with worms. This image is made without the use of a hide, in the company of 4 friends with cameras, lenses, chairs and at very short distance, about a couple of meters. I have never seen a behaviour like this on a wild bird. The additional meal that she is getting for acting as a model is a safe way to raise her babies for sure.:)
