Greater roadrunner
The greater roadrunner is a bird that loves to run. It has a long tail and a spiky crest, and it lives in hot, dry places.
The greater roadrunner is a long-legged member of the cuckoo family that lives in deserts and scrubby country in the southwestern United States and Mexico. It flies only a little but runs fast, chasing lizards, insects and even snakes, and it has clever ways of coping with desert heat.
Geococcyx californianus is a ground-dwelling cuckoo of arid and semi-open country from the US Southwest to Mexico. A weak flier but a fast runner, it eats almost any animal it can catch, saves water with salt glands near its eyes and warms itself by exposing dark skin to the sun.

Meet the roadrunner
The roadrunner is a bird that runs and runs.
It has long legs and a very long tail. It has a spiky crest on its head. Its feathers are brown, tan and streaky.
The greater roadrunner is about 52 to 54 centimeters long from the tip of its sturdy bill to the end of its white-tipped tail. It is brown and tan with dark streaks, a bushy blue-black crest and a patch of bare blue skin behind each eye.
It belongs to the cuckoo family, but it spends most of its life on the ground. When it runs, it holds its slim body almost flat, parallel to the ground, and steers with its long tail.
Geococcyx californianus is a member of the cuckoo family (Cuculidae), 52 to 54 centimeters long with a wingspan of about 49 centimeters and a mass of 221 to 538 grams, according to Cornell's All About Birds. Plumage is tan or brown with heavy blackish streaking above and on the chest; the black crown has small pale spots, and a patch of bare blue skin sits behind the eye.
It is built for the ground: Cornell describes it holding its lean body nearly parallel to the ground as it runs and using the long tail as a rudder. Its footprint is X-shaped, with two toes pointing forward and two backward.

Desert country
Roadrunners live in the United States and Mexico.
They like hot, dry land with bushes. You might see one dash across a quiet road.
Roadrunners live in the southwestern United States and in Mexico. They are famous desert birds, but they also live in grasslands, canyons, scrubby woods and open farmland, from below sea level to nearly 3,000 meters up in the mountains.
They stay in the same area all year. In recent years they have spread east into Missouri, Arkansas, Oklahoma and Louisiana. They avoid thick forests and crowded cities.
IUCN's 2022 global assessment lists the species as resident in Mexico and the United States. Cornell describes semi-open, scrubby habitat from below sea level to nearly 10,000 feet (about 3,000 meters): creosote and mesquite scrub, chaparral, grassland, streamside woods and canyons, and pinyon-juniper woodland higher up.
The range has expanded eastward into southwest Missouri, western Arkansas, eastern Oklahoma and Louisiana, where roadrunners use less typical habitat such as juniper landscapes and pine forests. Audubon notes that the range periodically expands north and east and is cut back by severe winters. The birds avoid dense forest and densely populated areas but tolerate sparse suburbs and open farmland.

A speedy hunter
Roadrunners eat bugs, lizards and mice.
They run fast to catch them. In winter they eat some fruit and seeds too.
Roadrunners eat almost any small animal they can catch: insects, scorpions, centipedes, lizards, snakes, frogs, mice and small birds. In winter, fruit and seeds make up about a tenth of their food.
A roadrunner hunts by walking quickly, then dashing forward to grab its prey in its bill. It can even jump straight up to snatch an insect flying past. Cornell's ornithologists report that roadrunners can catch and eat rattlesnakes.
Cornell describes the diet as mostly animal: small mammals, reptiles, frogs, toads, insects, centipedes, scorpions and birds, plus carrion, eggs and nestlings; in winter, fruit, seeds and other plant material make up about 10 percent. Audubon adds tarantulas, young ground squirrels and cactus fruit.
The usual method is a rapid walk followed by a sudden dash. Roadrunners leap straight up to take insects, bats and even hummingbirds in flight, and flash the white spots on their open wings to flush prey. Large prey is slammed against the ground or a rock to make it easier to swallow, and rattlesnakes are killed by repeated pecks to the head. Venomous lizards and scorpions are eaten with no ill effect.
Made for the desert
Roadrunners have tricks for the hot desert.
On cold mornings they sit in the sun to warm up. Their skin under the feathers is dark and soaks up the heat.
Cornell describes several ways roadrunners cope with the extremes of desert life: heat, cold nights and very little water. On a cold morning, a roadrunner turns its back to the sun and fluffs up its feathers to show patches of black skin, which soak up heat.
To save water, it gets rid of extra salt through a gland in front of each eye which uses less water than getting rid of it through the kidneys. Much of its water comes from the juicy animals it eats.
Cornell lists several adaptations to desert extremes. Like seabirds, roadrunners excrete a concentrated salt solution from a gland just in front of each eye, which uses less water than excreting salt through the kidneys. Moisture-rich prey such as mammals and reptiles supplies much of their water.
For heat, both chicks and adults flutter the bare skin under the chin (gular fluttering). For cold, they sunbathe: back to the sun, the bird raises the feathers on its back and wings to expose heat-absorbing black skin, sometimes several times a day in winter. Roadrunners are weak fliers; flight is mostly short bursts toward cover or glides from a perch to the ground.
Growing up
Mom and Dad roadrunner build a nest of sticks in a bush or a cactus.
The babies hatch with black skin and white fluff. Mom and Dad feed them for weeks.
Roadrunner pairs stay together for life. The male brings twigs and the female shapes them into a nest in a bush, cactus or small tree, about 1 to 3 meters off the ground. She lays two to six white eggs.
Both parents keep the eggs warm for about 19 to 20 days. The chicks hatch with their eyes closed, black skin and white down. They leave the nest after about 18 to 21 days, and their parents may keep feeding them for another 30 to 40 days.
Cornell describes lifelong pair bonds renewed each spring with courtship displays; Audubon says pairs defend a territory all year. The male brings twigs, which the female builds into a platform with a cup about 10 centimeters deep, lined with leaves, grass, feathers, snakeskin and flakes of manure, usually 3 to 10 feet (about 1 to 3 meters) up.
Clutches are 2 to 6 eggs, white with a chalky yellow film. Cornell gives incubation as 19 to 20 days; Audubon says both parents incubate, the male more. Hatchlings have closed eyes, black skin and white down but are strong and active. Young leave the nest after about 18 to 21 days and may be fed for another 30 to 40 days. The oldest banded roadrunner was at least 7 years old.
Running, cooing and sunbathing
A roadrunner can run very fast.
It makes soft cooing sounds, a bit like a dove. When it feels cross, it puts its crest up.
Audubon reports that a roadrunner can run about 24 kilometers an hour (15 miles an hour), perhaps faster in short spurts. It races along roads, dry streambeds and paths, and only flies when it really needs to.
A male calls with a slow, sad-sounding coo-cooo-coooo from a fence post or rock to mark the edge of his territory. When a roadrunner feels threatened, it raises its crest and shows a bright orange patch of skin behind its eye.
Roadrunners defend large territories, up to about half a mile (roughly 0.8 kilometers) across, which both members of a pair patrol. Males advertise boundaries with a mournful, descending coo from elevated perches; Audubon also lists clucks, dog-like whines and guttural notes.
Audubon gives running speed as about 15 miles per hour (24 kilometers per hour), with probably faster spurts when chasing prey. Threat and rival displays include a raised crest and an exposed orange patch of skin behind the eye. Courtship is elaborate: Cornell describes the male offering food such as a mouse during mating and then bowing, cooing and flicking his tail.
Did you know?
Real coyotes can run much faster than roadrunners.
Unlike in the cartoon, real coyotes can reach about 69 kilometers an hour (43 miles an hour), more than twice as fast as a roadrunner.
Cornell notes that coyotes, a genuine predator, reach about 43 miles per hour, more than twice a roadrunner's speed.
Is it in danger?
There are lots of roadrunners.
They are not in danger. They need wide open land to run and find food.
Roadrunners are common, and the IUCN Red List rates them Least Concern. Partners in Flight estimated in 2020 that about 1.4 million breed.
They still face problems. Cornell says the biggest is losing habitat, because roadrunners need lots of room, and new buildings and roads split up their territories. Pets, feral animals and traffic can also harm them, and their numbers in California have dropped a lot over several decades.
IUCN's 2022 global assessment lists Geococcyx californianus as Least Concern with an increasing population trend and about 1,400,000 mature individuals, the figure Partners in Flight gives for the global breeding population (2020), with a Continental Concern Score of 8 out of 20.
Cornell names illegal shooting, often based on the mistaken belief that roadrunners reduce game-bird populations, and, as the bigger threat, habitat loss and fragmentation that remove prey and nest sites. Pets, feral animals, pedestrians and traffic can displace or kill them, and California has seen a significant decline over the past several decades.

-
Roadrunners sunbathe to warm up on cold mornings.
After a cold desert night, a roadrunner turns its back to the sun and lifts its feathers to show dark skin that soaks up heat.
Morning sunbathing exposes black, heat-absorbing skin on the back; in winter a roadrunner may do it several times a day.
-
A roadrunner's footprint looks like the letter X.
Roadrunners have two toes pointing forward and two pointing back, so their footprints make an X shape.
With two toes forward and two back on each foot, the roadrunner leaves an X-shaped footprint.

Where does extra salt leave a roadrunner's body?
How does a roadrunner get rid of extra salt without wasting water?
Like seabirds, how do roadrunners get rid of concentrated salt while saving water?
- Through its feet
- Through a gland in front of each eye
- Through its tail feathers
Show the answer
Through a gland in front of each eye
Salt comes out near its eyes, from a special gland.
A gland in front of each eye gets rid of salt and uses less water than the kidneys would.
Like seabirds, it secretes concentrated salt solution from a gland in front of each eye, saving water compared with excretion through the kidneys.
