The Western Diamondback is a species of rattlesnake found primarily in the southwestern United States and parts of northern Mexico. It is easily recognizable by its distinctive diamond-shaped patterns along its back, which can vary in color from gray to brown. This snake typically grows to about 3 to 5 feet in length and is known for its rattle, which it uses as a warning signal when threatened. These snakes inhabit a variety of environments, including deserts, grasslands, and rocky areas. They are primarily nocturnal hunters, feeding on small mammals, birds, and lizards. The Western Diamondback plays an important role in its ecosystem by helping to control rodent populations.
