Timber Rattlesnake

Timber Rattlesnake Timber rattlesnake litters are usually divided between light and dark. The dark coloration is more common in northern Pennsylvania.
Adult Coloring The adult color phase, either light (yellow) or dark (black), have nothing to do with the sex and is simply a genetic trait. Researchers use the head color to reference the color phase rather than the body color of the snake.

More information for each snake may be found on the Pennsylvania Fish and Boat Commission website, through the links below.
