The chuck-will's-widow (Antrostomus carolinensis) is a nocturnal bird of the nightjar family Caprimulgidae. It is mostly found in the southeastern United States (with disjunct populations in Long Island, New York, Ontario, Canada and Cape Cod, Massachusetts) near swamps, rocky uplands, and pine woods. It migrates to the West Indies, Central America, and northwestern South America.
The chuck-will's-widow was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae . He placed it with all the other nightjars in the genus Caprimulgus and coined the binomial name Caprimulgus carolinensis. [3] Gmelin based his description on those of earlier authors including the "Goat-sucker of Carolina" that had been described and illustrated by the English naturalist Mark Catesby in his The Natural History of Carolina, Florida and the Bahama Islands that was published between 1729 and 1732. [4] Chuck-will's-widow is now placed with 11 other species in the genus Antrostomus that was erected by the French naturalist Charles Bonaparte in 1838. [5] [6] The generic name combines the Ancient Greek antron meaning "cavern" and stoma meaning "mouth". The specific epithet carolinensis is from the toponym Carolina. [7] The type locality is South Carolina. [8] The species is monotypic: no subspecies are recognised. [6]
The common English name "chuck-will's-widow " is an onomatopoeia from the bird's song. [9] Alternative names include "chuckwuts-widow" and "chip-fell-out-of-a-oak". [10]
This bird is sometimes confused with the better-known whippoorwill (Antrostomus vociferus), [11] because of their similar calls and unusual names. Though rather closely related, they are two distinct species.
The chuck-will's-widow has a short bill and a long tail typical of the nightjars. It has mottled brownish underparts, a buff throat, reddish-brown feathers lined with black, and brown and white patterning on head and chest. Males have patches of white on their outer tail feathers. It is the largest nightjar in North America. In length, it ranges from 28 to 33 cm (11 to 13 in). The wingspan can range from 58 to 66 cm (23 to 26 in). The body mass of the species is from 66 to 188 g (2.3 to 6.6 oz). [12] Among standard measurements, the wing chord is 20.1 to 22.5 cm (7.9 to 8.9 in), the tail is 13 to 15.1 cm (5.1 to 5.9 in), the bill is 1.1 to 1.4 cm (0.43 to 0.55 in) and the tarsus is 1.5 to 1.9 cm (0.59 to 0.75 in). [13]
The repetitive song is often heard at night. It consists of a series of calls with a vibrating middle note between two shorter notes, not much shifting in pitch. [14] It is slower, lower-pitched and less piercing than the song of the whip-poor-will.
It eats primarily insects, particularly those active at night such as moths, beetles, and winged ants. It will also eat small birds and bats, swallowing them whole. [15] [16]
The eggs are laid on patches of dead leaves on the ground. They are pink with spots of brown and lavender and are incubated by the female.
Nightjars are medium-sized nocturnal or crepuscular birds in the family Caprimulgidae and order Caprimulgiformes, characterised by long wings, short legs, and very short bills. They are sometimes called goatsuckers, due to the ancient folk tale that they sucked the milk from goats, or bugeaters, their primary source of food being insects. Some New World species are called nighthawks. The English word "nightjar" originally referred to the European nightjar.
Potoos are a group of birds related to the nightjars and frogmouths. They are sometimes called poor-me-ones, after their haunting calls. The family Nyctibiidae was formerly included with the nightjars in the order Caprimulgiformes but is now placed in a separate order, Nyctibiiformes. There are seven species in two genera in tropical Central and South America. Fossil evidence indicates that they also inhabited Europe during the Paleogene.
The eastern whip-poor-will is a medium-sized bird within the nightjar family, Caprimulgidae, 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.
The common potoo, or poor-me-ones, or urutau is one of seven species of birds within the genus Nyctibius. It is notable for its large, yellow eyes and comically wide mouth. Potoos are nocturnal and are related to nightjars and frogmouths. They lack the characteristic bristles around the mouths of true nightjars.
Nyctibius is a genus of potoos, nocturnal birds in the family Nyctibiidae.
The pauraque – also called the common pauraque to distinguish it from similar species – is a nightjar species, one of two birds in the genus Nyctidromus. It breeds in the subtropical and tropical regions of the New World, and except for northern most birds it is largely resident all year round.
Nyctidromus is a genus of nightjars in the family Caprimulgidae. The species are widely distributed in Central and South America.
Caprimulgus is a large and very widespread genus of nightjars, medium-sized nocturnal birds with long pointed wings, short legs and short bills. Caprimulgus is derived from the Latin capra, "nanny goat", and mulgere, "to milk", referring to an old myth that nightjars suck milk from goats. The common name "nightjar", first recorded in 1630, refers to the nocturnal habits of the bird, the second part of the name deriving from the distinctive churring song.
The savanna nightjar, sometimes also allied nightjar or Franklin's nightjar, is a species of nightjar found in South and Southeast Asia. Eight subspecies are recognised: C. a. monticolus, C. a. amoyensis, C. a. stictomus, C. a. affinis, C. a. timorensis, C. a. griseatus, C. a. mindanensis and C. a. propinquus. Its habitat is open forest and areas with scrub. Its length is about 25 cm (9.8 in). The upperparts are brownish-grey and vermiculated, with pale brown speckles. The underparts are brown, with bars. The savanna nightjar is nocturnal and is recognizable by its characteristic loud chirping calls, mainly given in flight during the evening. Their acoustic features change and can preadapt based upon their habitat. The IUCN Red List has assessed the species to be of least concern because it has a large range and its population trend is stable.
The great potoo or grand potoo is the largest potoo species and is widely distributed in Central and South America.
The white-tailed nightjar is a species of nightjar in the family Caprimulgidae. It is found in the tropic regions of Central and South America.
The montane nightjar, mountain nightjar or Abyssinian nightjar, is a species of nightjar in the family Caprimulgidae. It is native to upland regions of Central and Eastern Africa where it is a locally common species.
The rufous nightjar is a species of nightjar in the family Caprimulgidae. It is found in Argentina, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, Guyana, Panama, Paraguay, Peru, Saint Lucia, Suriname, Trinidad and Tobago, and Venezuela.
Hydropsalis is a genus of nightjars in the family Caprimulgidae. The species are widely distributed across the tropical and subtropical regions of the New World.
The scissor-tailed nightjar is a species of nightjar in the family Caprimulgidae. It is distributed over much of eastern South America.
Lurocalis is a genus of nightjar in the family Caprimulgidae. The species are found in Central and South America.
The short-tailed nighthawk is a species of nightjar in the family Caprimulgidae. It is found in Mexico, in every Central American country except El Salvador, in Trinidad and Tobago, and in every mainland South American country except Chile and Uruguay.
The northern potoo is a nocturnal bird belonging to the potoo family, Nyctibiidae. It is found from Mexico south to Costa Rica, and on the islands of Jamaica and Hispaniola. It was formerly classified as a subspecies of the common potoo but is now usually treated as a separate species based on differences in vocalizations.
Antrostomus is a genus of nightjars formerly included in the genus Caprimulgus. They are medium-sized nocturnal birds with long pointed wings, short legs and short bills.
