The most generally discovered reptilian species in the food plan (and sixth in general in 27 North American dietary studies) was the gopher snake (Pituophis catenifer). So much as is acknowledged, North American purple-tailed hawks have preyed upon 9 species of amphibian, 4 of which are toads. One hen species that typically flocks with pink-winged blackbirds in wintertime is even better represented in the crimson-tail’s diet program, the non-native seventy eight g (2.8 oz) European starling (Sturnus vulgaris), currently being the next most quite a few avian prey species and seventh total in North America. Among the uncommon cases of them capturing fish have included captures of wild channel catfish (Ictalurus punctatus), non-native typical carp (Cyprinus carpio) and decorative koi (Cyprinus rubrofuscus) as nicely some hawks that were observed scavenging on dead chum salmon (Oncorhynchus keta). Red-tailed hawks have been witnessed flying off with snake prey that may perhaps exceed 153 cm (5 ft in) in length in some scenarios. In North America, less lizards are generally recorded in the foods of crimson-tailed hawk than are snakes, in all probability since snakes are significantly much better adapted to cooler, seasonal climate, with an extensive diversity of lizards located only in the southernmost reaches of the contiguous United States.
