A problem solving technique used in automotive circles (and other industries) to find root casues is the 5-Why approach which sometimes can expose the root cause.
The problem: The Chuck-wills-widow is keeping this person awake at night.
Why is the Chuck in that location? A. The area of person's residence is prefered habitat of Chuck-wills.
Why is the Chuck's keeping this woman awake at night? A. Because of its calling throughout the night.
Why is it calling? A. Because that's what it does to attract a mate.
Why does it call to attract a mate? A. Because it doesn't have a mate.
The root cause of her being kept up at night may be argued that the calling Chuck-wills needs a mate.
Maybe the question we need be asking ourselves is not, "How to get rid of this calling bird?"; but possibly, "How can we attract a mate for this lonely calling bird?"
Just a thought from the other end of the spectrum.
I have a good friend that lives on top of an Ozark Mountain and there is a Chuck's will Widow that is driving her crazy, she wants to know what to do to get it to move somewhere else and call all night. She is desperate for a good nights sleep and will try anything to get the bird to move.............Does anyone know if playing a E. Screech Owl or Barred Owl recording will help?
