"Male Greater Roadrunners bring twigs to the female, which she fashions into a compact platform with a nest cup about 4 inches deep. A male that pauses for too long in his stickgathering may get reminded with a whining call from his partner, prompting him to get back to work. The finished nest can reach over 17 inches in diameter and 8 inches high, lined with leaves, grasses, feathers, smaller sticks, snakeskin, and flakes of cattle and horse manure. The parents may continue to work on the nest during incubation and build up the sides of the nest as the chicks grow. Pairs sometimes reuse a nest from a previous year.
