The species was intermediate in size between its two known congeners, being larger than S. brewsteri and smaller than S. americana. Olson considered that the cave deposits of the pauraque and other contemporary fauna were the prey of barn owls and were of Holocene age. Because of the cryptic nature of pauraques and other nightjars, Olson considered it possible that the species might not be extinct, though there have been no confirmed records of living birds.
