About Pantherophis bairdi (Yarrow, 1880)
Adults of Pantherophis bairdi can reach a total length (including the tail) of 64 to 140 cm, which equals 25 to 55 inches. The dorsal color pattern has a base shade ranging from orange-yellow to bright yellow, or a darker salmon, with four stripes running along the body from the neck to the tail. The underside is typically gray to yellow, and grows darker closer to the tail. Pantherophis bairdi occurs in the Big Bend region of western Texas in the United States, and also in the Mexican states of Coahuila, Nuevo León, and Tamaulipas in northern Mexico. This species is known to be elusive and difficult to locate in wild habitats. Pantherophis bairdi prefers semi-arid, rocky habitats.
