the canebrake rattlesnake is the southern version of the timber rattlesnake. canebrakes have a pinkish to light tan background (timbers are yellowish to black) and a marked stripe down their back (lacking in timbers). in winter, canebrakes hibernate alone while timber rattlesnakes hibernate in groups.
a common misconception is that you can tell the age of a rattlesnake by the size or number of segments (buttons) in its rattle. buttons are added with each shed, and snakes my shed several times each year, adding a button each time. rattles may also break off, so to find a wild rattlesnake with its original button still intact is extremely rare.
