Long-winged nightbird with intricate brown and gray patterning. Very similar to Common Nighthawk, best distinguished by voice. Gives a rapid series of hard, buzzy notes: "drik-rik-rik-rik." A Caribbean species; in the U.S., found only on the Florida Keys. Prefers open areas with mix of grass, bare ground, and shrubs. Nocturnal but can be seen hunting around dawn and dusk, searching for insects in flight.
