The banded rattlesnake is also known as the timber rattlesnake, Crotalus horridus. This venomous snake is native to North America and is recognized by its brown, banded pattern and distinctive diamond-shaped head. Other common names for the banded rattlesnake include the canebrake rattlesnake and the eastern diamondback rattlesnake. The rattlesnake's rattle, located at the end of its tail, makes a distinctive sound when the snake feels threatened. While the banded rattlesnake is feared for its venomous bite, it plays an important role in keeping rodent populations in check.
