Bull Snake Natural History 


Bull snakes vary in size, usually measuring 4 to 6 feet (122- 183 cm) in length but the largest individual was over 8 feet (244) long. They can weigh up to 3.6 kg (8 lbs).

Habitat and Distribution

Their large range extends southwards from the Canadian state of Alberta own to Tamaulipas in Mexico in semiarid and arid lands.


This species can live for over 20 years in captivity.


These are powerful constrictors which eat small mammals such as mice, rats and moles as well as small birds, eggs, small reptiles and amphibians.

Groups and Breeding

They breed during March/ April. A clutch of eggs usually has 4-15 eggs which the mother will leave alone to incubate, usually in sand. The eggs then hatch in August or September and hatchlings may be over 16 inches (41 cm) in length.


The IUCN lists this snake as least concern due to their large population and huge range.

Interesting facts

Bull snakes have a loud hiss which they use as a defence mechanism.
