Quick Answer
To identify a rattlesnake by its rattle, listen for the distinct sound created by the vibration of loose, dry skin segments at the end of the tail, typically 3 to 8 in number, and check for corresponding rattle marks. Count the number of rattle segments to determine the species. Be cautious, as some species may mimic the sound or appearance.
Understanding Rattle Sounds
Rattlesnakes produce a unique sound by rapidly vibrating the loose skin segments, or “buttons,” at the end of their tail. These segments are usually 3 to 8 in number, and some species have as many as 20. The number and size of the buttons can indicate the species, but it’s crucial to note that some species may have altered or missing buttons due to injury or old age. Listen carefully to the distinct sound of each species to determine the correct identification.
Identifying Rattle Marks
Each rattlesnake species has a specific pattern of rattle marks that can be found on the underside of its tail. These marks are formed by the growth of new skin segments, which create a visible line or pattern. Look for distinctive patterns such as a single row of buttons, a double row, or a series of concentric circles. By counting the number of rattle segments and examining the rattle marks, you can determine the species and take necessary precautions.
Field Identification Techniques
When hunting for rattlesnakes, use the following techniques to identify a snake’s rattle: approach the snake with caution and listen for the sound of the rattle; observe the snake’s tail from a safe distance to count the number of rattle segments; and examine the underside of the tail for rattle marks. Use a pair of binoculars to observe the snake without disturbing it. Always exercise extreme caution when approaching a rattlesnake, as its rattle may not always be audible or visible.
