>> I lost hearing in my left ear from Afghanistan 4 years ago so it's hard to tell sometimes where they actually are.
>> Lucky, sound waves do weird things. I don't have any real hearing problems but have discovered sound easily bounces off walls, fences, bushes, tree lines & such. You can think the noise is coming from the exact opposite direction from where it is actually coming from.
I agree. Those tree frogs' calls seem especially elusive. They seem to be coming from all directions even when it's just 1-2 frogs. I almost never see them where I live, but I heard ONE a few weeks ago. He seemed lonely!
