That's NOT a Diamondback rattlesnake!
It's a gorgeous and beautiful, beneficial, wonderful Gray Rat snake. (Pantherophis obsoletus spiloides)
Completely harmless.

I don't have any idea why you would think that's a rattlesnake, lol!
Anyway, nice to see the video of that beauty. I sure hope you wouldn't hurt it!
It's hoping to find mice or rats and it's taking shelter from the heat of the day.
I'll bet you're somewhere up in northern Florida....perhaps in the general area of Cedar Key over to Sanderson or
west of that, due to coloration....I also don't know from the video how far away it is from shedding again. The chocolate brown is sometimes more of a lighter gray in the area I describe, except for when I say west of that general line across the top of the state.
I met a gorgeous lighter colored one in Osceola National Forest, off of route 10. The color is variable up there.
It's basically a more southerly form of the Black Rat snake.
A very, very cool snake to find.
I'd give almost anything to live where you do!
