Habitat:

Found in desert scrub, chaparral, rocky outcrops, and occasionally grasslands. Can be found from sea level to 1500 m.

Diet:

Mammals (mice, rats, squirrels, rabbits), and birds.

Venom:

Hemorrhagic toxins, resulting in tissue damage and edema.

Remarks:

The red diamond rattlesnake can be quite passive and is usually reluctant to rattle or strike. This is in sharp contrast to its similar looking and aggressive cousin the western diamondback rattlesnake. However, because of their size they can deliver a large amount of venom in a bite so they should be considered dangerous.
