Thanks for the response.
As visually impaired as I was, they were flying literally a small creeks width away and I couldn't hear a thing. I'm 90% sure they were small owls. I was thinking screech b/c it seemed one had some reddishness to it, but my guide says barred are the ones that live along 'river bottoms'.
I'll go earlier and only use the red bulb if I feel I need to.
