Geographic range
P. bairdi is found in the United States in the Big Bend region of western Texas, as well as in northern Mexico in the Mexican states of Coahuila, Nuevo León, and Tamaulipas. Known to be elusive and hard to find in the wild.
Etymology
The specific name, bairdi, as well as several of the common names, are in honor of American zoologist Spencer Fullerton Baird.
Description
Adults of P. bairdi may reach 64 to 140 cm (25 to 55 in) in total length (body + tail). The dorsal color pattern consists of an orange-yellow to bright yellow, or a darker salmon ground color, overlaid with four stripes that run from the neck to the tail. The belly is generally gray to yellow, darkening near the tail.

Reproduction
P. bairdi is oviparous. Adult females may lay a clutch of up to 10 eggs that take about 3 months to hatch.
Habitat
P. bairdi prefers semi-arid, rocky habitats.
Common names
Baird's rat snake, Baird's ratsnake, Baird's pilot snake, Baird's Coluber, Great Bend rat snake.
