Stenopsis |
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. [1]
Caprimulgus nightjars are found around Afro-Eurasia and Australasia, and like other nightjars they usually nest on the ground. They are mostly active in the late evening and early morning or at night, and feed predominantly on moths and other large flying insects.
Most have small feet, of little use for walking, and their soft plumage is cryptically coloured to resemble bark or leaves. Some species, unusually for birds, perch along a branch, rather than across it, which helps to conceal them during the day. Temperate species are strongly migratory, wintering in the tropics.
Caprimulgus species have relatively long bills and rictal bristles. Many have repetitive and often mechanical songs.
The genus Caprimulgus was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae . [2] The type species is the European nightjar (Caprimulgus europaeus). [3] The name is the Latin word for a nightjar; it combines capra meaning "nanny goat" and mulgere meaning "to milk". [4] The myth that nightjars suck milk from goats is recounted by Pliny the Elder in his Natural History : "Those called goat-suckers, which resemble a rather large blackbird, are night thieves. They enter the shepherds' stalls and fly to the goats' udders in order to suck their milk, which injures the udder and makes it perish, and the goats they have milked in this way gradually go blind." [5]
The genus contains 39 species. [6]
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 nighthawk is a nocturnal bird of the subfamily Chordeilinae, within the nightjar family, Caprimulgidae, native to the western hemisphere. The term "nighthawk", first recorded in the King James Bible of 1611, was originally a local name in England for the European nightjar. Its use in the Americas to refer to members of the genus Chordeiles and related genera was first recorded in 1778.
The lesser yellowlegs is a medium-sized shorebird. It breeds in the boreal forest region of North America.
The red-necked nightjar is the largest of the nightjars occurring in Europe. It breeds in Iberia and North Africa, and winters in tropical West Africa.
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".
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.
The black-bellied sandgrouse is a medium large bird in the sandgrouse family.
The anis are the three species of birds in the genus Crotophaga of the cuckoo family. They are essentially tropical New World birds, although the range of two species just reaches the United States.
The chuck-will's-widow is a nocturnal bird of the nightjar family Caprimulgidae. It is mostly found in the southeastern United States near swamps, rocky uplands, and pine woods. It migrates to the West Indies, Central America, and northwestern South America.
The painted sandgrouse is a medium large bird in the sandgrouse family Pteroclidae found in India and Pakistan.
The genus Paradisaea consists of six species of birds-of-paradise. The genus is found on the island of New Guinea as well as the nearby islands groups of the Aru Islands, D'Entrecasteaux Islands and Raja Ampat Islands. The species inhabit a range of forest types from sea level to mid-montane forests. Several species have highly restricted distributions, and all species have disjunct distributions. A 2009 study examining the mitochondrial DNA of the family found that the Paradisaea birds-of-paradise were in a clade with the genus Cicinnurus. It showed that the blue bird-of-paradise was a sister taxon to all the other species in this genus.
The great potoo or grand potoo is the largest potoo species and is widely distributed in Central and South America.
The purple-naped lory is a species of parrot in the family Psittaculidae. It is forest-dwelling endemic to the islands of Seram, Ambon, and perhaps also Haruku and Saparua, South Maluku, Indonesia. It is considered endangered, the main threat being from trapping for the cage-bird trade.
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 scissor-tailed nightjar is a species of nightjar in the family Caprimulgidae. It is distributed over much of eastern 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 Jamaican poorwill, also known as the Jamaican pauraque or Jamaican least pauraque, is a species of nightjar in the family Caprimulgidae. It is endemic to Jamaica and has not been recorded since 1860.
The yellow-billed amazon, also called the yellow-billed parrot or Jamaican amazon, is a species of parrot in the family Psittacidae. It is a predominantly green parrot with a short tail and pink throat and neck. It is endemic to Jamaica, where its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical mangrove forests, subtropical or tropical moist montane forests, plantations, and rural gardens. It is threatened by habitat loss and illegal trapping of wild birds for the pet trade.
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.
