Crotalus oreganus helleri
This adult snake was about 4 feet long with dark diamond pattern down the top of the body. There's a dark line starting at the eye that extends across the "cheek". The video shows it coiled and you can hear the loud rattle. This species is responsible for the most human bite records in the US.
It was stretched out and wound in between rocks when I first walked up on it. It very quickly shot out of the rocks, coiled and started its loud rattle. The snake and rock pile was along a dirt trail near Lake Hodges.
The juvenile can be seen at my other spotting: http://www.projectnoah.org/spottings/756... "Most species of rattlesnakes have hemotoxic venom, destroying tissue, causing necrosis and coagulopathy (disrupted blood clotting). Rattlesnake bites are the leading cause of snakebite injuries in North America, and cause approximately 82% of fatalities. rattlesnakes have two organs that can sense radiation: their eyes, and a set of heat-sensing "pits" on their face that enable them to locate prey and strike towards it, based on the prey's thermal radiation signature." When threatened, they contract special "shaker" muscles in the tail causing the chamber segments to vibrate against one another, making the rattling noise (which is amplified because the segments are hollow). - Wikipedia
