Details

Habitat

It ranges from southeastern Canada through the United States, Mexico, Central America and into northern South America. Forest, grassland, farms, rocky slopes and settlements are all used.

Appearance

Adults are roughly 60-175 cm long and 200-1300 g. Pattern varies widely by region, from bright tri-colored bands to blotched or muted forms.

Behavior

Usually solitary, it is often nocturnal or crepuscular. In cooler regions it hibernates in dry upland shelters or underground retreats.

Feeding

It constricts small mammals, lizards, birds, eggs and other snakes. The species is harmless to people and subdues prey with body coils rather than venom.

Reproduction

Females lay about 3-24 eggs in early summer under logs, rocks or rotting vegetation. Incubation lasts roughly two months.

Notes

The name comes from a folk belief that the snake drank milk from cows. It was more likely entering barns to hunt rodents.
