We recorded the predation on the rattlesnake Crotalus helleri caliginis, endemic to Coronado Sur Island, Baja California, based on the discovery of bone remains of two snakes in the falcon pellets of the Peregrine Falcon Falco peregrinus. This record represents the first confirmed predation of the insular snake and expands our knowledge of the Peregrine Falcon diet on the island.
