Coachwhip snake eating a rattlesnake, spotted by a roadrunner.

2 full view

3 prey fully swallowed; however when the eater finally left it looked and moved more normal

4/5 a roadrunner came over and sized up the feast; but I couldnt stand to lose two snakes in one afternoon so I opened the window and pounded on the wall, and it left. No good options.

6 length of exposed prey snake that I saw when I first discovered the situation
