The chicken snake, aka caninana, serpiente tigre, tiger rat snake, or yellow rat snake, is a nonvenomous colubrid that hails from Mexico, Central America, north and central South America, Tobago, and Trinidad. Often found near water, these snakes prefer forested areas. Even though they face the threats of habitat destruction at the hands of dams and agriculture, these critters are still listed as Least Concern by the IUCN. Their populations are stable across their range.
