The Black Rat Snake is a proficient climber. Often it goes rather high up into trees, where it uses cavities or hollows formerly occupied by other animals such as birds or mammals. Black Rat Snakes often hibernate in rock crevices in the company of other snakes, such as copperheads and rattlesnakes.
A number of species sometimes share the same den, especially black rat snakes, timber rattlesnakes and copperheads. The black rat snake is often referred to as the âpilotâs nake because it is supposed it âpilotsâ the way for the others to the den in winter and away from the den in spring.
