Humans are just as interested in roadrunners as they are in us, and when one approaches on foot and cocks its head, it's a sight to see. Roadrunners have elaborate mating rituals, and may mate for life. Their courtship begins with the male chasing the female on foot. Like other bird species, the male tries to woo the female with food, often bringing her a lizard in his beak. Both males and females try to attract each other with offerings of sticks or grass.
The male wags its tail and leaps into the air to get attention. Males also make cooing sounds, which can be heard here , provided by the Macaulay Library. Once a pair mates, they stay together to defend their territory all year. The birds build a nest in a low bush or tree and line it with grass, leaves, and sometimes cow dung. Each pair has two to eight eggs each breeding season. Most pairs raise the young together, taking turns protecting the hatchlings and procuring food.
On cool desert nights, roadrunners enter a state of torpor, allowing their body temperature to drop to conserve their energy. When daytime temperatures drop in winter, they use the sun to warm up several times a day.

Roadrunners have a crest at the top of the head that can puff up when the bird is trying to communicate with other roadrunners. Roadrunners call with a series of "coo" sounds. They can be seen in deserts, brush, and grasslands on the ground or sitting on low perches, such as fences. Predators of roadrunners are raccoons , hawks, and, of course, coyotes.
Greater roadrunners eat a wide variety of foods, including rodents, reptiles , small mammals, and insects. Due to the harsh environment of the Southwest, roadrunners will eat whatever is available.
As desert-dwellers, they get much of the water they need from the prey that they eat. Greater roadrunner pairs may mate for life. A male greater roadrunners put on displays to tempt a female to mate.
Sometimes the male will dangle a food offering, such as a lizard or snake, from his beak to entice the female. Other times, the male will wag his tail while bowing and making a whirring or cooing sound, then he jumps into the air and onto his mate. The breeding and nesting seasons vary by region. In regions where there is one rainy season, the birds nest only in the spring. Where there's more rain, and thus more food resources, they will nest again in August and September.
Greater roadrunners can have between two and eight eggs per brood, which are white or pale yellow. Greater roadrunners are occasionally brood parasites, which means they rely on other birds to raise their young. For example, roadrunner eggs have been observed in the nests of the common raven and the northern mockingbird.
Young can run and catch their own prey about three weeks after hatching.
