Do snakes hibernate in tennessee11/4/2023 ![]() Snakes are most active whenever temperatures are between 80-90F. If food is in their stomach or intestines when they cool, it will rot and kill them. If the snake feeds heavily before they hibernate, and have digested their meal before the cooling starts, they will be OK. ![]() Barns or under houses are other good spots for snakes. Other places include holes under the roots of a tree or inside a rotting log. Rodent burrows are probably the most common places for sleeping snakes, especially in southern states such as Texas. Thus, the effective range of a downhill strike may exceed that normally expected across a level surface.Ĭaves and deep crevices on rocky hillsides are common hibernaculums for rattlers. On very steep slopes, a snake could lose balance during a strike and actually fall toward its target. If striking downhill, however, gravity and the momentum generated by a strike may combine to carry the animal farther forward than would occur over flat ground. That means a three foot long snake may be able to strike a distance of two feet. As a rule of thumb, rattlesnakes can strike a distance of two-thirds their total body length. Just like humans, snakes head out to enjoy the sun and unsuspecting hikers can startle them and cause them to strike. Nice sunny winter days that follow a long cold snap are often when people are surprised by snakes. On warm days, brumating snakes sometimes come out of their dens to bask in the sunshine. If male snakes don't cool down at some point during the year, they most likely would not be able to produce fertile sperm. Brumation or hibernation is necessary for breeding. Snakes don't actually sleep in Brumation, but their bodies acclimate to a lower temperature, their metabolism slows, and they become less active and less inclined to feed. Hibernation is a deep sleep, usually occuring in colder, snow covered climates in northern states. In warmer southern states, snakes often don't go into hibernation, but brumation. Generally, rattlesnakes emerge from hibernation in March or April, or when the average daytime temperatures reach and remain about 60 degrees Fahrenhei t and higher. Snake activity picks up as temperatures fall in late summer and early autumn before they go into hibernation, which can be as early as September or as late as December. Venomous snakes from North America, such as rattlers, copperheads, and cottonmouths, hibernate when the weather cools down. Snakes from tropical climates, such as pythons and boas, don't hibernate at all. A snake in Minnesota will go into hibernation much earlier than a snake in Texas, and come out of hibernation much later. When snakes in the wild go into hibernation depends on two things: their location and their species.
