When I saw the title I was kinda shocked cuz I didn't know there was a bird called Roadrunner. The first thing that the word "Roadrunner" reminds me of is Plymouth Roadrunner, so when I saw the title I was like "WTF?!".
I never would have thought that bird would try and kill a rattler.... then it ate it and im like.. O_O
I have seen a squirrel go after a snake before.. that was pretty darn impressive too
