Determining gender in natural populations is important for studying population dynamics, population structure, habitat use, behavior and mating systems, and for making management decisions Hughes , Ito et al. Lovette of Cornell University Lovette et al. Unfortunately, for many species, it is difficult to determine sex using morphometrics and plumage Ito et al. Because females are heterogametic, sex in birds can also be determined using a molecular technique, polymerase chain reaction PCR amplification of DNA. It can run 15 miles per hour, probably with much faster spurts when chasing a fast-running lizard or other prey.

Year-round weather-dependent behavior of the Roadrunner Geococcyx californianus. Living Bird Greater Roadrunners are monogamous, maintain a long-term pair bond, and mutually defend a large, multipurpose territory. May be in long-term decline in California. Historically, the Greater Roadrunner has been persecuted by ranchers and hunters who believe that it consumes the young and eggs of popular game bird species. An opportunistic predator, it feeds on snakes, lizards, spiders, scorpions, insects, birds, rodents, and bats, which it beats repeatedly against a hard substrate before consuming. Its prowess as a rattlesnake fighter has been much exaggerated, but it does eat a remarkable variety of smaller creatures. American Journal of Physiology Various combinations of measurements were run in the DFA to account for differences in the types of measurements taken at other banding sites.
