The mother may carry the eggshells to another location or consume a portion of them. The defecation is pungent.The common nighthawk breeds during the period of mid-March to early October.The preferred breeding/nesting habitat is in forested regions with expansive rocky outcrops, in clearings, in burned areasIt is a solitary nester, putting great distances between itself and other pairs of the same species, but a nest would more commonly occur in closer proximity to other species of birds.
