The Timber rattlesnake (Crotalus horridus) is a species of venomous Pit vipers. It lives in eastern United States of America. There are no subspecies currently recognized.

Description[change | change source]

Adults usually grow up to the length of 91–152 cm (35.8-59.8 in). The longest to be reported was 189.2 cm (74.5 in) long. Large Timber Rattlesnakes weigh about 4.5 kg (9.9 Ib), but most weigh about 580-900 g (20-32 oz). There scales are usually yellowish-brown or gray with dark brown or black stripes.

Where they live[change | change source]

They are found in woodlands and forests of eastern United States of America, from southern Minnesota and southern New Hampshire, south to east Texas and north Florida. During the summer pregnant females prefer open, rocky ledges, where the temperature is higher, while males and non-pregnant females spend more time in cooler woodlands with a closed forest canopy. Females usually bask in the sun before having babies in open rocky areas, known as "basking knolls". In the winter Timber Rattlesnakes hibernate in dens and caves.

Feeding[change | change source]

They mainly eat small mammals but they also eat birds, frogs, and other snakes like rattlesnakes. The most common snake they eat is the Garter Snake
