Eastern Whip-poor-will - Antrostomus vociferus

The Whip-poor-will is heard more often than seen, as it chants it's whip-poor-will in rapid succession, often for long periods of time. During daylight hours, they sleep motionless on the forest floor, and can be very difficult to spot because of their mottled camouflaged feathering. Probably the easiest way to spot a bird in the daytime is if the nest is approached too closely, which often prompts the parent to hover in place while investigating the intruder. There are slight but distinct differences in plumage and voice between eastern and western populations in North America, and there is some who classify the two as different species.
