Rattlesnake compared to Gopher snake ID

Bull snake (actually this is a sonoran gopher snake) vs prairie rattlesnake. Bonus horned lizard.
The gopher snake is a large, non-venomous constrictor snake found across North America, known for its tan or yellow body with dark blotches and its ability to mimic a rattlesnake by shaking its tail when threatened. These snakes are beneficial predators, feeding on rodents like gophers, as well as birds, eggs, and lizards. They are not dangerous to humans and are often mistaken for rattlesnakes due to their similar appearance and defensive behaviors.

The Prairie Rattlesnake (Crotalus viridis) is a venomous pit viper found across the Great Plains of North America, from Canada to Mexico. It is characterized by a triangular head, a stout body with dark blotches that form rings near the tail, and a heat-sensing pit organ between its eye and nostril. These snakes are ovoviviparous, giving birth to live young in late summer or early fall, and their diet consists mainly of small mammals. They are known for their distinctive rattle, which is used to warn predators, and they hibernate communally in dens.
