Roadrunners are among the fastest-running birds on the planet. In short, they can sprint up to about 26 miles per hour (roughly 41 kilometers per hour) in short bursts, with many individuals commonly clocking speeds around 20 mph (32 km/h) in typical runs. They achieve these speeds thanks to long legs, muscular hind limbs, and an efficient running gait, and they can still fly when needed, though they rely on ground speed to escape predators and catch prey. Details to know:
- Greater roadrunner: up to about 26 mph (41 km/h) in full sprint.
 - Lesser roadrunner: typically around 20 mph (32 km/h).
 - General behavior: despite being capable of flight, roadrunners predominantly run on the ground to navigate their desert habitats and pursue prey. They can take to the air when necessary, such as to escape threats or reach prey in trees or shrubs.
 
If you need, I can share a quick comparison with other fast-running birds or provide sources for these speed figures.
