Very little is known about the reproductive biology of Yucatan Nightjar. Specimens collected in March had enlarged gonads, and a nest was discovered on Cozumel Island in June (Paynter 1955). This nest site was not described, but presumably the eggs were laid on the ground. The clutch of this nest contained two eggs; the eggs were white, marked with irregular chocolate brown blotches (Paynter 1955). Dimensions of one egg were 30.0 x 21.5 mm (Paynter 1955).
