Behaviour and diet

Roadrunners spend much of their time foraging on the ground and are opportunistic omnivores. Their diet can include insects, reptiles, small mammals, birds, eggs, and fruits or seeds.

Conservation and cultural significance

The greater roadrunner is listed as least concern and is considered stable overall. It is also widely recognized in popular culture, especially through its association with the American Southwest and cartoon depictions.
