A Mojave Rattlesnake. The best way to tell it apart from the Western Diamondback is by the extra width of the white bands just above the rattle as shown in your video at 2:30 where it shows the white bands double the width of the black bands. With the WDB, the white and black bands are very close to the same width.
These two snakes are among the most dangerous in the USA and are difficult to tell apart. And it is important to know if getting bit because of the antivenom--very different. The Mojave venom is closer to the way cobra bite works--on the nervous system. The WDB works on the respiratory system.
Nevertheless, here in this RV Park they catch them alive and relocate them farther out in the desert, they do not kill them, and neither would I.
