The sound of wings -- no longer just for us boondockers

As someone who lives in a semi rural area and am a lifetime hunter and outdoorsman I never even thought there may be people who have never heard the sound of bird wings. On a quiet, still morning sitting in the woods just before it is light enough to see and there is the sudden sound of heavy wings of ducks passing just over the tree tops it will definitely get your attention. And even more so in the dark and an owl swoops thru the trees just overhead with a soft “swoosh” can make your hair stand on end. :E
