About the Western diamondback rattlesnake
Western diamondback rattlesnakes are ambush predators that feed primarily on small mammals, birds, and lizards, using heat-sensing pits to locate prey. They are typically active from dusk to dawn and may rattle their tail as a warning when threatened, but will often remain still to avoid detection.
