Timber Rattlesnake (Crotalus horridus) is a robust venomous snake equipped with a broad triangular head, with heat sensitive pits. It is mostly found in deciduous forests in rugged terrain. During summer, females prefer open and rocky edges where the temperature is higher as compared to males who sped more time in cooler, denser woodland. Their preys are mostly small animals like frogs, birds etc. They use chemical cues to ambush their prey.
