It weighs 227 to 341 grams (0.5 to 0.75 lb), grows up to 58 cm (23 in) long, and stands about 25 to 30 cm (10 to 12 in) tall, with a wingspan of 43 to 61 cm. The oldest banded wild bird recovered was 7 years old. It ranges from California, Nevada and Utah east to Kansas, Arkansas and Louisiana, and south into Mexico, favoring arid desert with scattered brush for cover and open grassy areas for foraging. It will fly only when it absolutely has to, and even then it stays airborne for only a few seconds. On the ground it is a different story. It can hit speeds of up to 20 miles per hour, using its long tail for steering, braking, and balance. That speed is its main defense: [coyotes](/animals/coyote/), hawks, house cats, skunks and raccoons prey on it, and it relies largely on its swiftness to outrun them. ## An Opportunist With a Rock for a Weapon The roadrunner eats pretty much anything it can catch: large insects, scorpions, tarantulas, centipedes, lizards, snakes, and mice, plus birds and eggs, and it also feeds on prickly pear cactus where it's available. Rattlesnakes have been known to end up on the menu too, although this is rare. When hunting, the bird walks fast, scanning for prey, then dashes forward to make the catch, sometimes jumping into the air to snatch a passing insect. To kill something like a rodent, it smashes the prey's body and head against a rock and then swallows it whole. Birds of the World adds that it beats snakes and other prey repeatedly against a hard surface before eating them. ## Running Cold, Running Hot At night it enters hypothermia to conserve energy. In the morning and on cooler days, it positions its scapular feathers so the black skin underneath can absorb sunlight and warm the body. > **Basking saves energy** Under artificial sunlight, sunning roadrunners kept a normal resting metabolism at air temperatures as low as 9°C. Basking saved them an average of 551 calories an hour, where a calorie is the small unit scientists use: about half of one food Calorie. Midday heat brings the opposite problem, and one way the bird copes is by cutting its activity by 50%. ## How to Spot One Its feet have two toes pointing forward and two pointing back, which leaves a distinctive X-shaped track. A crest of black feathers rises and falls at will, and a bare streak of blue and red skin runs behind each eye. Listen for it too: roadrunners are often mistaken for mourning doves, because of their cooing call, usually six to eight coos that drop in pitch. ## Frequently Asked Questions ### How fast can a greater roadrunner run? It can reach speeds of up to 20 miles per hour on the ground. It can fly for short distances, but it prefers to remain on the ground, where it hunts for prey. *(Source: [White Sands National Park, National Park Service]())* ### Does a roadrunner really fight rattlesnakes? Rarely. Rattlesnakes are known from its diet, but Animal Diversity Web calls them a rare meal. Its regular menu runs from large insects, scorpions and tarantulas to lizards, other snakes and mice, and it kills small prey such as rodents by smashing them against a rock. *(Source: [Animal Diversity Web, University of Michigan]())* ### How does a roadrunner survive cold desert nights? In the dark it may let its body temperature drop into hypothermia, then warm back to normal by sunning itself, at a reduced energy cost. Under artificial sunlight, basking birds kept a normal resting metabolism in air as cold as 9°C and saved an average of 551 calories an hour, which is about half of one food Calorie. *(Source: [Ohmart & Lasiewski 1971]())* ### How long does a greater roadrunner live? Bird banding has recovered a wild roadrunner at 7 years old, the oldest banded bird recovered, and one bird lived 9 years in captivity. *(Source: [AnAge: The Animal Ageing and Longevity Database, Human Ageing Genomic Resources]())* ## Sources 1.
