Yes, there are two species of roadrunner birds that can be found in the state of Arizona – the Greater Roadrunner and the Lesser Roadrunner. Roadrunners are iconic birds of the desert southwest and are well known for their incredible running speed and zany antics.
Quick Facts About Roadrunners
Here are some quick facts about roadrunner birds in Arizona:
- Roadrunners belong to the cuckoo family (Cuculidae). There are two species found in Arizona – the Greater Roadrunner (Geococcyx californianus) and the Lesser Roadrunner (Geococcyx velox).
- Roadrunners can reach speeds of up to 20 miles per hour while running. They prefer sprinting to flying.
- Roadrunners get their name from their habit of racing down roads in front of moving vehicles.
- Roadrunners stand about 2 feet tall and have long tails and crests on their heads that flop around when they run.
- Roadrunners are omnivores and eat a variety of prey including snakes, lizards, mice, insects, and berries.
- Roadrunners kill prey by smashing it against the ground. They are one of the few birds known to hunt reptiles.
- Roadrunners can survive in hot, arid environments like the Sonoran Desert thanks to their ability to minimize water loss.
- Roadrunners lay about 12 eggs per year and often reuse old nests built by other birds.
- Greater Roadrunners are common year-round residents across Arizona while Lesser Roadrunners are rarer summer residents in the southeastern part of the state.
Range and Habitat of Roadrunners in Arizona
Roadrunners occupy a variety of arid to semi-arid habitats across Arizona. Here is a breakdown of where each species can be found:
Greater Roadrunner – Found across most of Arizona excluding the higher mountainous regions. Occupies desert scrub, chaparral, grasslands, agricultural areas, suburbs, and parks. Common in areas like the Sonoran Desert near Phoenix and Tucson.
Lesser Roadrunner – Restricted to southeastern Arizona in the Sky Islands region. Prefers oak woodlands and pine-oak forests at higher elevations above 4,000 feet.
Roadrunners do well in hot, dry environments with ample bare ground and low vegetation that allows them to run freely and spot prey. They have adapted to live close to human settlements, often foraging along the edges of farms, golf courses, and suburban neighborhoods.
Identification and Behavior
Roadrunners have several distinctive features that aid in identification:
- Long black-and-white barred tail
- Shaggy crest that flops around when running
- Long curved beak
- Reddish brown body with streaking on the chest
- Yellow eyes
- Blue patches of bare skin behind the eyes
In terms of behavior, roadrunners are diurnal, terrestrial birds best known for their frequent sprinting and rapid foot movements. They can often be spotted darting across roads, parking lots, trails, and other open areas in search of food.
Roadrunners may also be seen perching on low trees, fences, or other vantage points scanning for prey. They have a slow, bobbing walk but can burst into high speed running when chasing prey. Their long tails help them make quick turns.
Roadrunners are generally non-vocal birds but may emit low coos or whinnying calls, especially between breeding pairs. They also give a rattling call when disturbed. During the breeding season, male roadrunners may engage in elaborate courtship displays involving foot drumming and running loops around females.
Hunting, Diet, and Feeding Behavior
Roadrunners are opportunistic predators and scavengers with a highly varied diet. They hunt a wide range of small animals including snakes, lizards, rodents, scorpions, spiders, beetles, grasshoppers, centipedes, caterpillars, and more. Common prey items include whiptail lizards, bullsnakes, and pocket mice.
Roadrunners use a combination of running, walking, and stealth tactics when hunting, stalking slowly up to prey before breaking into a sprint. Their strong beaks allow them to subdue and kill larger prey. Roadrunners are one of the few predators quick enough to catch hummingbirds.
Roadrunners supplement their diet with various plant material when animal prey is scarce. This includes berries, fruits, seeds, acorns, tender greens, and even prickly pear cactus pads. Roadrunners also drink free water when available but can survive long periods by metabolizing water in their food sources.
Feeding activity is concentrated in the early morning and late afternoon. At midday, roadrunners often rest in the shade of a tree or shrub to avoid the hottest temperatures. They are highly opportunistic and move from area to area in search of food.
Breeding and Nesting
The breeding season for roadrunners in Arizona runs from early March through July. Courtship displays begin in early spring. The male roadrunner shows off with foot drumming displays and running loops around the female while cooing loudly.
Once paired, the male and female work together to build a nest – an untidy platform of sticks often lined with grass, feathers, snake skins, or other material. Nests are usually placed 1-15 feet above ground in a tree, bush, or cactus. Roadrunners sometimes refurbish old nests built by other bird species.
The female lays a clutch of 2-12 white eggs which are incubated by both parents for about 20 days until hatching. The chicks are covered in downy feathers and can leave the nest after 18 days, but continue to be fed and protected by the parents for another 18 days or more.
Roadrunner pairs are monogamous and may re-nest up to four times in a season if the first few attempts fail. Once the chicks become independent, the parents typically go their separate ways until the next breeding season.
Interactions with Humans
The iconic roadrunner has a long history of interactions with Native American cultures and later European settlers in Arizona. Roadrunners figure prominently in the myths and folklore of Southwestern tribes who considered them symbols of protection.
Today, roadrunners have adapted well to living near human settlements across Arizona. However, they face some threats including:
- Habitat loss and fragmentation
- Being struck by vehicles when running across roads
- Predation by domestic cats, dogs, and foxes
- Use of pesticides and rodent baits that reduce prey
Roadrunners are protected under the Migratory Bird Treaty Act and it is illegal to harm, harass, or kill them without a permit. They provide free pest control services around homes and farms by eating rodents, snakes, and other small critters.
Many Arizonans enjoy seeing roadrunners darting around parks, neighborhoods, and backyards. They are charismatic birds that have become cultural icons of the American southwest. Proper precautions should be taken not to purposefully feed roadrunners or make them habituated to humans.
Roadrunner viewing tips
Here are some tips for finding and observing roadrunners in Arizona:
- Search areas of open desert scrub or sparse grasslands with scattered shrubs and trees.
- Scan low perches like fence posts, stumps, rocks, and branches where roadrunners may sit and hunt.
- Drive or walk slowly down rural roads – roadrunners are known to sprint out ahead of vehicles.
- Listen for rattling or cooing vocalizations which may reveal a roadrunner’s presence.
- Use bird feeders, platforms, and water features to potentially attract roadrunners into your yard.
- Be patient and stop frequently to scan for movement – you may catch a roadrunner dashing by.
- Aim for early mornings and evenings when roadrunners are most actively hunting and foraging.
- Consider joining a birding tour that targets roadrunners and other desert birds.
Popular spots to potentially see roadrunners in Arizona include Saguaro National Park, Sonoran Desert National Monument, Sabino Canyon Recreation Area, Picacho Peak State Park, Catalina State Park, and the desert areas around Phoenix and Tucson.
Conclusion
In summary, the iconic Greater Roadrunner and Lesser Roadrunner are signature birds found across much of Arizona’s arid landscapes. Roadrunners thrive in desert scrub but have also adapted to life around human settlements. Their distinctive appearance, quirky behavior, and blazing running speed make them popular and easily-recognizable birds for Arizona residents and visitors alike to observe.
