The pattern of the marking of this species is finer and more mottled with rusty than the Nighthawk. Its habits do not differ to any extent from those of the preceding species; they lay their two mottled gray eggs upon the bare ground, often on the dry sand and in arid regions where they are exposed, with no protection, to the scorching rays of the sun. The eggs vary endlessly in extent of markings,some being very pale and others very dark gray, mottled with various shades of gray, brown and lilac. Size 1.10 x .75.
