Caprimulgus vociferus Wilson, 1812
The eastern whip-poor-will (Antrostomus vociferus) is a medium-sized (22–27 cm) nightjar from North America. The whip-poor-will is commonly heard within its range, but less often seen because of its camouflage. It is named onomatopoeically after its song.
This medium-sized nightjar measures 22–27 cm (8.7–10.6 in) in length, spans 45–50 cm (18–20 in) across the wings and weighs 42–69 g (1.5–2.4 oz). Further standard measurements are a wing chord of 14.7 to 16.9 cm (5.8 to 6.7 in), a tail of 10.5 to 12.8 cm (4.1 to 5.0 in), a bill of 1 to 1.4 cm (0.39 to 0.55 in) and a tarsus of 1.5 to 1.8 cm (0.59 to 0.71 in). Adults have mottled plumage: the upperparts are grey, black and brown; the lower parts are grey and black. They have a very short bill and a black throat. Males have a white patch below the throat and white tips on the outer tail feathers; in the female, these parts are light brown.
Eastern whip-poor-wills breed in deciduous or mixed woods across central and southeastern Canada and the eastern United States, and migrate to the southeastern United States and to eastern Mexico and Central America for the winter. These birds forage at night, catching insects in flight, and normally sleep during the day. Eastern whip-poor-wills nest on the ground, in shaded locations among dead leaves, and usually lay two eggs at a time. The bird will commonly remain on the nest unless almost stepped upon.
The eastern whip-poor-will is becoming locally rare. Several reasons for the decline are proposed, such as loss of early successional forest habitat, habitat destruction, predation by feral cats and dogs, and poisoning by insecticides, but the actual causes remain elusive. Even with local populations endangered, the species as a whole is not considered globally threatened due to its large range.
The whip-poor-will has been split into two species. Eastern populations are now referred to as the eastern whip-poor-will. The disjunct population in southwestern United States and Mexico is now referred to as the Mexican whip-poor-will, Antrostomus arizonae. The two populations were split based on range, different vocalizations, different egg coloration, and DNA sequencing showing differentiation.
In 2018, the eastern whip-poor-will was uplisted from least concern to near threatened on the IUCN Red List, on the basis that based on citizen science observations, populations of the eastern whip-poor-will had declined by over 60% between 1970 and 2014. This decline is likely due to decreased forest disturbance and early successional forest habitat, pesticides and intensified agriculture, both of which have led to heavy declines in the flying insect populations that the eastern whip-poor-will depends on, as well as habitat loss. BirdLife International has stated that initiatives like the Conservation Reserve Program will be crucial in conserving the species and reversing its decline.
Due to its song, the eastern whip-poor-will is the topic of numerous legends. A New England legend says the whip-poor-will can sense a soul departing, and can capture it as it flees. This is used as a plot device in H. P. Lovecraft's story The Dunwich Horror. Lovecraft based this idea on information of local legends given to him by Edith Miniter of North Wilbraham, Massachusetts when he visited her in 1928. This is likely related to an earlier Native American and general American folk belief that the singing of the birds is a death omen. This is also referred by Whip-poor-will, a short story by James Thurber, in which the constant nighttime singing of a whip-poor-will results in maddening insomnia of the protagonist Mr Kinstrey who eventually loses his mind and kills everyone in his house, including himself. The bird also features, however, in The Runaway Slave at Pilgrim's Point, a poem by the English poet Elizabeth Barrett Browning, in which the outcast speaker asks: "Could the whip-poor-will or the cat of the glen/Look into my eyes and be bold?"
It is also frequently used as an auditory symbol of rural America, as in Washington Irving's story The Legend of Sleepy Hollow, or as a plot device. For example, William Faulkner's short story, "Barn Burning", makes several mentions of whip-poor-wills, e.g.: "and then he found that he had been asleep because he knew it was almost dawn, the night almost over. He could tell that from the whip-poor-wills. They were everywhere now among the dark trees below him, constant and inflectioned and ceaseless, so that, as the instant for giving over to the day birds drew nearer and nearer, there was no interval at all between them."
"The Mountain Whippoorwill" is a poem written by Stephen Vincent Benet about a fiddling contest, won by Hillbilly Jim, who refers to his fiddle as a whip-poor-will and identifies the bird with the lonely and poor but vibrant life of the mountain people. American poet Robert Frost described the sound of a whip-poor-will in the fourth stanza of his 1915 poem "Ghost House". This is notable in Frost's use of assonance, in "The whippoorwill is coming to shout / And hush and cluck and flutter about."
In the 1934 Frank Capra film It Happened One Night, before Clark Gable's character Peter Warne reveals his name to Ellie Andrews (Claudette Colbert), he famously says to her: "I am the whip-poor-will that cries in the night".
The standard tune "My Blue Heaven", written in 1924 by Walter Donaldson and George A. Whiting, and popularized by a 1928 Gene Austin recording, opens with the words, "When whip-poor-wills call, and evening is nigh, I hurry to my blue heaven."
Hank Williams's 1949 song "I'm So Lonesome I Could Cry" opens with the lyric, "Hear that lonesome whip-poor-will/He sounds too blue to fly." Alan Jackson's song "Midnight in Montgomery" refers to the whip-poor-will with the lyrics "Cause it's midnight in Montgomery. Just hear that whip-poor-will". The swing classic "The Birth of the Blues" contains the line "From a whippoorwill high on a hill they took a new note / pushed it through a horn 'til it was worn into a blue note". The whippoorwill is also referenced in Hank Williams Jr's song "I'm Gonna Get Drunk and Play Hank Williams All Night Long" with the lyrics "Cause the wedding bells will never ring for me/And that whippoorwill ain't got no sympathy". Jim Croce too makes a reference to this bird in his song "I got a name": "Like the whip-poor-will and the baby's cry, I've got a song, I've got a song".
In the 1957 Jay Livingston/Ray Evans Oscar-nominated song "Tammy" for the motion picture "Tammy and the Bachelor," the first two lines of the second verse were, "Whippoorwill, whippoorwill, you and I know, Tammy! Tammy! Can't let him go!". The song, which reached #1 on the Billboard Hot 100, was sung by the movie's star, Debbie Reynolds.
Elton John and Bernie Taupin's 1975 song "Philadelphia Freedom" features a flute mimicking the call of the eastern whip-poor-will and includes the lyrics "I like living easy without family ties, till the whippoorwill of freedom zapped me right between the eyes."
US country band Blackberry Smoke released a 2012 album called The Whippoorwill, whose title song features the lyrics "I dreamed I heard that Whippoorwill sing, She sang my song and called me by name, I hung my head in shame".
Singer-songwriter Richard Shindell released his song, "So Says The Whippoorwill" on his 2004 album Vuelta. The song was written as a tribute to fellow songwriter, Dave Carter, who died of a heart attack on 19 July 2002.
The Pennsylvania-based Indie rock band Dr Dog released their song "Lonesome" on their 2012 album "Be the void", featuring the passage "I had my fill of the Whippoorwill / When he broke into song I shot him".
Country singer Randy Travis' love song "Deeper Than The Holler" released as the second single on the album "Old 8x10" features the line "And longer than the song of a Whippoorwill" at the end of the chorus.

- For example, Henninger (1906) combines the old scientific name of C. carolinensis with the common name "whip-poor-will". As C. carolinensis does not occur in the area discussed, he obviously refers to C. vociferus. In other cases, the specific identity of birds may not be determinable.
