kingfisher calls

I have heard that some one/some people in the kingfisher hide are using pre recorded kingfisher calls probably on their smart phone to play out loud in order to get photos. I have to say, that for someone to spend thousands on equipment and to sit there to get photos of kingfishers which virtually pose for you, this is a really stupid and selfish move. All it takes is for the nest to be deserted and you've not only broken the law but you'll have killed the chicks in the nest as well as upset hundreds of people... You should not, repeat not, play any bird calls out loud in the spring or summer especially when you know you're near a nest. It can cause the birds to desert the nest and breaks the law.
