You won't find any rattlesnakes in Alaska, Delaware, Hawaii, Maine, and Rhode Island. Until recently, southern populations of the Timber Rattlesnake were widely recognized as a separate subspecies, the canebrake rattlesnake (C. h. atricaudatus) (Schmidt and Davis, 1941; Anderson, 1965; Martof et al., 1980).
