CROTALUS VIRIDIS (Prairie Rattlesnake). DIET. Crotalus viridis feeds on small mammals (mice, ground squirrels, rats, small rabbits); it will also consume lizards, amphibians, and other snakes.  On 3 July 2012, an adult C. viridis was photographed attempting to consume a still quivering adult male Falco sparverius (American Kestrel) at the Chihuahuan Desert Rangeland Research Center, Summerford Mountain (32.532536°N, 106.790825°W; datum WGS84), New Mexico, USA). On 06 July 2012, the site was revisited and the kestrel was found, apparently regurgitated, after being swallowed down to the top of the wings. To our knowledge, this represents the first case of attempted predation on F. sparverius by C. viridis.
