Western Diamondback Rattlesnake
The Western Diamondback Rattlesnake is solitary except during the mating season. Usually inactive between late October and early March, these ectotherms occasionally may be seen basking in the sun on warm winter days. In the winter, they hibernate or brumate in caves or burrows, sometimes with many other species of snakes. Life expectancy is more than 20 years.

Its habitats range from flat coastal plains to steep rocky canyons and hillsides; it is associated with many different vegetation types, including desert, sandy creosote areas, mesquite grassland, desert scrub, and pine-oak forests. It is common to see the western diamondback on rural blacktop roads in early evening, because of the heat retention of these surfaces, as ambient temperatures drops.

They are poor climbers.

They are one of the more aggressive rattlesnake species in the US in the way that they stand their ground when confronted by a foe. If rattling does not work, then the snake will strike in defense.
