Well there is the possiblity that the whistling sound was actually furtherer away, and the conditions made it travel well.  Was it a clear night?  Little to no wind?  I am by no means trying to downplay anything, just trying to give a possible explantion to help put you at ease.  
I, myself, am a scared-y-cat. I will not go outside after dark without someone to accompany me, unless I absolutely have to. If I was in your shoes I know I would be just as afraid and I would want to hear other explanations to help make me less afraid of my own home and property.
		
 I do think the game cam is a good idea, I would get one if I could.  Perhaps a motion sensor light?

 Anyway I am praying for safety and protection for yourself and your family.  I hope you figure out the mystery! (and keep us posted, I am also curious!)
