The number of birds on this planet is decreasing by a dangerous amount.
Do your bit for biodiversity and talk to bird/wildlife biologists and find out how to lure these birds to a place where they will want to build a different nest.
Yes, I know that some wildlife folks blame cats for the decrease in birds, but when you think about the number human animals who have used weed and feed and tried to make their lawns monocultural, you will realize that humans are the big problem.
As I say talk to those who will help you make these birds want to go elsewhere.
