Sonoran Whipsnake

Masticophis bilineatus


The Sonoran whipsnake is a long, slender snake reaching lengths between 2 and 5 feet (60 to 150 cm). The head is broad with large eyes. It is olive or bluish-gray fading to yellow towards the tail, with 2 or 3 light-colored stripes on each side. The belly is cream fading to pale yellow towards the tail


Chiefly a Mexican species, the Sonoran whipsnake enters the United States in extreme southwestern New Mexico and southeastern to west-central Arizona. In Mexico, it is found south to Oaxaca. The Sonoran whipsnake is most commonly found in rocky canyons, riparian areas, foothills and mountains with dense vegetation in elevations up to 6100 feet (1800 m). However, this snake is also found in open creosote bush flats. It is equally at home on the ground or in low, shrubby vegetation. Look for the Sonoran whipsnake in areas with ocotillos, saguaros, and palo verdes, but also in chaparral, cottonwood, juniper, and pine-oak forests

Hey Tajminator! Thanks for adding to the Snakes of the Southwest Mission! Looks like a whipsnake (Masticophis) of some kind, either a coachwhip (M. flagellum) or Sonoran whipsnake (M. bilineatus). I'm leaning more towards Sonoran whipsnake based on coloration, but coachwhips can be pretty variable.
