Diamondback Rattlesnake wakes up suddenly!

"Rattlesnakes use their rattle to warn others.  They may rattle to indicate they are present so they won’t be stepped on, or they may rattle if cornered or harassed to warn that they may be about to strike." "Tail-rattling is mainly a defensive gesture; something they do when frightened."
