The red-necked nightjar (Caprimulgus ruficollis) is the largest of the nightjars occurring in Europe. It breeds in Iberia and North Africa, and winters in tropical West Africa.
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 specific ruficollis is from Latin rufus, "red", and collum, "neck". [2]
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. [3]
There are two subspecies: nominate ruficollis, breeding in Iberia, and desertorum breeding in North Africa. The North African form desertorum is paler than the Iberian one, and has different patterning on the base of its primary feathers: dark and orange bands of approximately equal width, compared to the narrower orange bands and greater extent of black of ruficollis. [4]
The variegated plumage resembles the European nightjar. The adult is lichen-grey, barred and streaked with buff, chestnut and black. The underparts are barred. It is larger and longer-tailed than the more widespread species, and has a rufous neck-collar. Both sexes have white wing spots, tail sides and throat. During the day this nightjar lies silent upon the ground, concealed by its plumage; it is difficult to detect, looking like a bit of lichen-covered twig or a fragment of bark. The length is 32 cm, and the wingspan 64 cm. Like other nightjars, it has a wide gape, long wings, soft downy plumage and nocturnal habits.
Its call is a repetitive mechanical kyok-kyok-kyok..., which rises and falls as the bird turns its head from side to side. When it churrs, the bird lies or crouches along a branch or rail, but it will sing from a post. During courtship, and occasionally at other times, it uses a mechanical signal, a sharp cracking sound, caused by clapping the wings together over the back.
Open sandy heaths with trees or bushes are the haunts of this crepuscular nightjar. It flies at dusk, most often at sundown, with an easy, silent moth-like flight; its strong and deliberate wingbeats alternate with graceful sweeps and wheels with motionless wings. Crepuscular insects, such as moths, are its food.
It is a late migrant, seldom appearing in the breeding area before the end of April or beginning of May. No nest is made; the two elongated and elliptical eggs are placed upon the bare ground; the brooding bird, sitting closely, is their best protection.
The species has occurred as a vagrant twice in northern Europe, in Northumberland, Britain in October 1856, [4] and in Denmark in 1991. [5] The Northumberland bird was shot at Killingworth on 5 October by a gamekeeper, and the specimen purchased by John Hancock. [6] In 2006, Keith Vinicombe and Dominic Mitchell cast doubt on the British record, believing that the lack of detail around the circumstances of finding indicated that a mistake or fraud could not be ruled out. [7] The British Ornithologists' Union Records Committee subsequently re-examined the record and came to the conclusion that it should continue to be regarded as acceptable. [4] [8] The British record is a first-autumn bird of the Iberian race ruficollis, and the Danish record also appears to be of this form; earlier suggestions that the British bird was of the North African race desertorum were erroneous – the specimen's paleness being due to fading whilst on public display at the Hancock Museum. [4] [9] There are also several nineteenth-century European records from outside the species' normal breeding range: from southeast France, Malta, the Canary Islands, Croatia, Israel and Sicily. [4]
The European nightjar, common goatsucker, Eurasian nightjar or just nightjar, is a crepuscular and nocturnal bird in the nightjar family that breeds across most of Europe and the Palearctic to Mongolia and Northwestern China. The Latin generic name refers to the old myth that the nocturnal nightjar suckled from goats, causing them to cease to give milk. The six subspecies differ clinally, the birds becoming smaller and paler towards the east of the range. All populations are migratory, wintering in sub-Saharan Africa. Their densely patterned grey and brown plumage makes individuals difficult to see in the daytime when they rest on the ground or perch motionless along a branch, although the male shows white patches in the wings and tail as he flies at night.
The Egyptian nightjar is a medium-small nightjar which occurs in south west Asia and north Africa and winters in tropical Africa. This is a fairly common species with a wide distribution which faces no obvious threats apart from habitat destruction, so the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The standard-winged nightjar is a nocturnal bird in the nightjar family.
Jerdon's nightjar is a medium-sized nightjar species native to southern India and Sri Lanka. Formerly considered as a subspecies of the long-tailed nightjar, it is best recognized by its distinctive call which sounds like a wooden plank being beaten periodically with each note ending in a quaver. The common name commemorates Thomas C. Jerdon who described the species.
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 northernmost birds it is largely resident all year round.
Prigogine's nightjar or the Itombwe nightjar, is a bird species of tropical central Africa. It is known from only one specimen taken at Malenge in the Itombwe Mountains in Zaire in August 1955.
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 common poorwill is a nocturnal bird of the family Caprimulgidae, the nightjars. It is found from British Columbia and southeastern Alberta, through the western United States to northern Mexico. The bird's habitat is dry, open areas with grasses or shrubs, and even stony desert slopes with very little vegetation.
The pennant-winged nightjar is a species of nightjar that occurs from Nigeria to northern South Africa. It is an intra-African migrant and displays remarkable sexual dimorphism in the breeding season.
Bates's nightjar or the forest nightjar, is a bird species of the family Caprimulgidae, found in the rainforests of western Sub-Saharan Africa.
The golden nightjar is a species of nightjar in the family Caprimulgidae. It is found in Sahel region in northern Sub-Saharan Africa.
The square-tailed nightjar is a species of nightjar in the family Caprimulgidae which is native to tropical and subtropical woodlands of the Afrotropics. It has an extensive range south of the African equator. Despite not having a completely "square tail", its naming highlights a distinguishing field mark. The similarly plumaged slender-tailed nightjar, found in dry bush country of the tropics, differs namely by its protruding central tail feathers. It is alternatively known as the Gabon nightjar or Gaboon nightjar or the Mozambique nightjar.
The fiery-necked nightjar is a species of nightjar in the family Caprimulgidae, which is found mostly in Africa south of the equator, though it has been spotted in a few countries north of the equator. It is most often found in woodland savannas or other deciduous woodlands. It is usually distinguished by its tawny coloured collar which gives the species its common name. It has a distinctive call that many have rendered as 'good-lord-deliver-us'. The fiery-necked nightjar is an insectivorous species that mostly eats butterflies, moths and other insects. The fiery-necked nightjar breeds after the dry season and typically produce two clutches with two eggs per clutch.
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-cheeked nightjar is a species of nightjar in the family Caprimulgidae. It is an intra-African migrant that breeds in the south of its range. It spends the non-breeding season in eastern Nigeria, Cameroon, southern Chad and Sudan, the Republic of the Congo, the D.R.C. and western Central African Republic. Throughout the year it can be found in Southern Africa. It is a nocturnal species that feeds on flying insects, mainly hunting at dusk and the early night. They can hunt at night thanks to their large eyes that are adept at seeing in the dark. They cannot see in complete darkness and most likely cannot see colours either. The rufous-cheeked nightjar forms monogamous pairs and the egg laying period is from September to November. It looks very similar to other African nightjars and they are frequently misidentified during research and studies.
The freckled nightjar or freckled rock nightjar is a species of nightjar in the family Caprimulgidae. It has a wide yet patchy distribution throughout the Afrotropics.
The spotted nightjar or spotted eared-nightjar is a species of nightjar in the family Caprimulgidae. It inhabits much of mainland Australia and has also been found in several Indonesian islands. Its natural habitats are open forests and woodlands, scrub, spinifex and tussock grassland, savannah woodland and mangroves.
John Hancock was an English naturalist, ornithologist, taxidermist and landscape architect. Working during the golden age of taxidermy when mounted animals became a popular part of Victorian era interior design, Hancock is considered the father of modern taxidermy
