Habitat
Varied habitats including grasslands, rocky hillsides, pine forests, and brushlands. They prefer areas with plenty of cover like flat rocks, logs, and debris for hiding. Usually found below 8,000 feet elevation.
Diet & Feeding
Opportunistic carnivores; they hunt primarily at night for small mammals, lizards, birds, and other snakes. They kill prey via constriction.
Reproduction
Oviparous (egg-laying). Females typically lay a clutch of 4 to 12 eggs in early summer, which hatch in late summer or early autumn.
Conservation Status
Least Concern (IUCN). Generally stable, though habitat loss and road mortality are localized threats.
Cultural Significance
Named from the folklore myth that they sucked milk from cows' udders; in reality, they were simply attracted to barns to hunt rodents. They provide significant ecological benefit via pest control.
Notable Features
Exhibits Batesian mimicry by evolving a color pattern that resembles coral snakes to deter predators.
