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.

Description
The tiger rattlesnake (Crotalus tigris) is a highly venomous pit viper species found in the southwestern United States and northwestern Mexico. The color pattern consists of a gray, lavender, blue-gray, pink, or buff ground color that usually turns to pink, pale orange, or cream on the sides.Wikipedia ↗
Habitat
The species' range extends from central Arizona south through south-central Arizona in the United States, to southern Sonora, Mexico, including Isla Tiburón in the Gulf of California and was recently discovered in the southern Peloncillo Mountains of Arizona. Tiger rattlesnakes habitats include rocky desert canyons, foothills, and bajadas, in vegetation zones ranging from thornscrub, ocotillo-mesquite-creosote bush, saguaro-paloverde, mesquite grassland, and chaparral to tropical deciduous forest (southern Sonora) and the lower edge of oak woodland.Wikipedia ↗

Tiger rattlesnakes are terrestrial snakes and are nocturnal during the hot summer (June–August), but become diurnal and crepuscular during the fall season. They hibernate during the late fall and winter in rock crevices or animal burrows.Wikipedia ↗
