For the first time, a case of predation on a Haemorhous mexicanus nest by the dusky rattlesnake Crotalus aquilus is presented. The phenomenon of gluttony by this rattlesnake, which may have caused the death of the snake is also documented; since it had already eaten an adult Peromyscus maniculatus before consuming the 4 chicks in the nest.
