I observed a nest of a red-tailed hawk (Buteo jamaicensis) for 13.5 h over a 4-day period in April 2012 along the Mexican border in southwestern Arizona. I documented prey items (N = 7) brought into the nest, including six representing the following three previously undocumented species of reptiles: Yuman Desert fringe-toed lizard (Uma rufopunctata), sidewinder (Crotalus cerastes), and western shovel-nosed snake (Chionactis occipitalis).
