Keep Herp Calendar free
Hi, I'm Nick. I built Herp Calendar on my own and I keep it free, with no ads. If it has helped you find a herp this season, a small tip goes straight into the hosting and the data work. Only if you can spare it. Either way, I'm glad you're here.

Timber Rattlesnake
Crotalus horridus
Description
The timber rattlesnake (Crotalus horridus), also known commonly as the banded rattlesnake, and the canebrake rattlesnake in the southern United States, is a species of pit viper in the family Viperidae. Adults usually grow to total length of 91–152 cm (36–60 in).Wikipedia ↗
Habitat
C. horridus can be found in a variety of terrestrial habitats including lowland cane thickets (thus the common name canebrake rattlesnake), high areas around swamps and river floodplains, hardwood and pine forests, mountainous areas, and rural habitats in farming areas. During the summer, gravid females seem to prefer open, rocky ledges where the temperatures are higher, while males and nongravid females tend to spend more time in cooler, denser woodland with more closed forest canopy.Wikipedia ↗
When it's active
During the winter, timber rattlesnakes brumate in dens and limestone crevices, often together with copperheads (Agkistrodon contortrix) and rat snakes (Pantherophis alleghaniensis, P. obsoletus, and P. spiloides). Males often mate farther away from winter hibernacula than females.Wikipedia ↗
Venom
The neurotoxic component of the type A venom is referred to as canebrake toxin, and is a phospholipase A2.Wikipedia ↗
