Estimate the length of the western diamondback rattlesnake. This species averages between 34 and 84 inches long, meaning the largest specimens approach lengths of 7 feet. The western diamondback rattlesnake features a stout body and a large head, separated by what resembles a neck, according to the "National Audubon Society Field Guide to Reptiles and Amphibians."
Inspect the head of the western diamondback rattlesnake, looking for specific features. The head will have a triangular shape and it possesses heat-seeking pits below each nostril that are used to locate its prey during nocturnal hunts. Darkened stripes run from the eyes on each side toward the snake's upper lip.
Look at the tail of the western diamondback rattlesnake, observing the rattle composed of keratin. Each time the snake sheds its skin, a dry segment adds on to the rattle. The snake vibrates these as a warning when confronted with a threat. The tail of this species features obvious black and white rings as well, states the Washington Nature Mapping Program.
Study the coloration and markings on the back and body of the snake. Look for light-bordered blotches and diamond-shaped patterns on the back. The western diamondback rattlesnake is not one uniform color, with snakes being shades and mixes of gray, brown, pink and yellow above, with its diamond pattern often blackish or tan.
Watch the behavior of this snake when threatened. Keep well away as you observe the western diamondback, a snake that typically does not flee from a fight. It stands its ground, with its head raised above its coiled body and its noisy rattle vibrating. It will strike if you get too close; more people endure bites from this particular snake than from any of the other poisonous types in North America.
