Thanks so much! You've identified a lot of my spottings! It's greatly appreciated!

While watching them I noticed their abdomens were hairless. Unfortunately my pictures are a bit blurry when zooming in and they do appear fuzzy, but they weren't.
They also seemed small to me.
I wish I had taken more time to observe and document. I will strive to be better from now on.
Thanks for all your help and input!

Thanks Machi!
This was taken inside Carter Caves State Park in Kentucky. Our campsite was surrounded by White Oaks, but I can't recall for certain that this was one of them.
Most were quite busy and didn't pay any attention to me. I watched them for a few minutes and noticed that some did not move at all, not sure if they were alive or not.

Thanks! The bill should have convinced me, but the heavily striped neck made me doubt.

Thanks again!

He's actually on the sunroof of my car. It does look as though he's jumping!

Thanks, I figured it might be a robin. I just wasn't sure with the dark beak!
Thanks again!

Possibly a Rusty Crayfish.
Nice capture!

Thanks, Alice!

Thanks, I'll change it shortly and read up about it!
