Their nests are smaller than those of the greater roadrunner, but are stronger and more compact, built in the shape of a cup with sturdy grass stems and twigs, with a diameter of ca 14.5 cm. Both male and female roadrunners incubate. Lesser roadrunner clutches show less variation in size than those of the greater roadrunner, and from observation, all eggs appear to hatch around the same time.
