Breeding and Nesting
Gray Nightjar: Two cream or white-blue eggs with black-brown blotches are laid on a bare scrape on the ground. No materials are used for the nest because the color and pattern of the eggs, and plumage of the female blend in with their surroundings. Female incubates the eggs for 16 to 17 days.
