Caprimulgiformes
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 (the Latin for goatsucker is ''caprimulgus''), 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. Nightjars are found all around the world, with the exception of Antarctica and certain island groups such as the Seychelles. They can be found in a variety of habitats, most commonly the open country with some vegetation. They usually nest on the ground, with a habit of resting and roosting on roads. The subfamilies of nightjars have similar characteristics, including small feet, of little use for walking, and long, pointed wings. Typical nightjars, though, have rictal bristle ...

Strisores
Strisores ( ) is a clade of birds that includes the living families and orders Caprimulgidae (nightjars, nighthawks and allies), Nyctibiidae (potoos), Steatornithidae (oilbirds), Podargidae (frogmouths), Apodiformes (swifts and hummingbirds), as well as the Aegotheliformes (owlet-nightjars) whose distinctness was only recently realized. The Apodiformes (which include the " Trochiliformes" of the Sibley-Ahlquist taxonomy) and the Aegotheliformes form the Daedalornithes. Description The material evidence for this group is very equivocal; the most ancient Strisores are quite nondescript tree-dwellers but already tend towards peculiarly apomorphic feet, and no Cretaceous fossils are known. Torpor and other metabolic peculiarities are very frequently found in this group, perhaps more often than in any other bird lineage. The synapomorphies that define this clade are the ''ossa maxillaria'' separated by a large cleft, a mandible with very short ''pars symphysialis'', and ''ram ...

Potoo
Potoos (family Nyctibiidae) 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. Potoos are nocturnal insectivores that lack the bristles around the mouth found in the true nightjars. They hunt from a perch like a shrike or flycatcher. During the day they perch upright on tree stumps, camouflaged to look like part of the stump. The single spotted egg is laid directly on the top of a stump. In Argentina and Bolivia, they are known as kakuy or cacuy from Quechua meaning 'to remain'. In Brazil, they are called urutau from Guaraní ''guyra'' 'bird' and ''tau'' 'ghost'.

Eurostopodinae
The eared nightjars are a small group of nocturnal birds in the nightjar family, although the taxonomy is uncertain. There are seven species, mainly found in forest and scrub from China to Australia. 5 species are placed in the genus, ''Eurostopodus'', the other two species in ''Lyncornis''. They are long winged birds with plumage patterned with grey and brown to camouflage them when resting on the ground. They feed on insects caught in flight. A single white egg is laid directly on the ground and incubated by both adults. The chicks can walk soon after hatching. Taxonomy The order Caprimulgiformes contains several families of nocturnal insectivores, these are the frogmouths, the potoos, the oilbird and the nightjars. The latter family is normally split into two subfamilies, the American nighthawks, Chordelinae, and the typical nightjars Caprimulginae.Cleere (1998) p. 15 The eared nightjars are sometimes considered a subfamily Eurostopodinae of the Caprimulgidae but some studies ...

Owlet-nightjar
Owlet-nightjars are small crepuscular birds related to the nightjars and frogmouths. Most are native to New Guinea, but some species extend to Australia, the Moluccas, and New Caledonia. A flightless species from New Zealand is extinct. There is a single monotypic family Aegothelidae with the genus ''Aegotheles''. Owlet-nightjars are insectivores which hunt mostly in the air but sometimes on the ground; their soft plumage is a cryptic mixture of browns and paler shades, they have fairly small, weak feet (but larger and stronger than those of a frogmouth or a nightjar), a tiny bill that opens extraordinarily wide, surrounded by prominent whiskers. The wings are short, with 10 primaries and about 11 secondaries; the tail long and rounded. Systematics A comprehensive 2003 study analyzing mtDNA sequences Cytochrome b and ATPase subunit 8 suggests that 11 living species of owlet-nightjar should be recognized, as well as another that became extinct early in the second millennium A ...

Oilbird
The oilbird (''Steatornis caripensis''), locally known as the , is a bird species found in the northern areas of South America including the Caribbean island of Trinidad. It is the only species in the genus ''Steatornis'', the family Steatornithidae, and the order Steatornithiformes. Nesting in colonies in caves, oilbirds are nocturnal feeders on the fruits of the oil palm and tropical laurels. They are the only nocturnal flying fruit-eating birds in the world (the kakapo, also nocturnal, is flightless). They forage at night, with specially adapted eyesight. However, they navigate by echolocation in the same way as bats, one of the few birds to do so. They produce a high-pitched clicking sound of around 2 kHz that is audible to humans. Taxonomy and etymology Oilbirds are related to the nightjars and have sometimes been placed with these in the order Caprimulgiformes. However, the nightjars and their relatives are insectivores while the oilbird is a specialist fructivor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apodiformes
Traditionally, the bird order Apodiformes contained three living families: the swifts (Apodidae), the treeswifts (Hemiprocnidae), and the hummingbirds (Trochilidae). In the Sibley-Ahlquist taxonomy, this order is raised to a superorder Apodimorphae in which hummingbirds are separated as a new order, Trochiliformes. With nearly 450 species identified to date, they are the most diverse order of birds after the passerines. Description As their name ("footless" in Greek) suggests, their legs are small and have limited function aside from perching. The feet are covered with bare skin rather than the scales (scutes) that other birds have. Another shared characteristic is long wings with short, stout humerus bones. The evolution of these wing characteristics has provided the hummingbird with ideal wings for hovering.Mayr, Gerald (2003): Phylogeny of early tertiary swifts and hummingbirds (Aves: Apodiformes).

Frogmouth
The frogmouths are a group of nocturnal birds related to owlet-nightjars, swifts, and hummingbirds. Species in the group are distributed in the Indomalayan and Australasian realms. Biology They are named for their large flattened hooked bill and huge frog-like gape, which they use to capture insects. The three ''Podargus'' species are large frogmouths restricted to Australia and New Guinea, that have massive flat broad bills. They are known to take larger prey such as small vertebrates (frogs, mice, etc.), which are sometimes beaten against a stone before swallowing. The ten ''Batrachostomus'' frogmouths are found in tropical Asia. They have smaller, more rounded bills and are predominantly insectivorous. Both ''Podargus'' and ''Batrachostomus'' have bristles around the base of the bill, and ''Batrachostomus'' has other, longer bristles which may exist to protect the eyes from insect prey. In April 2007, a new species of frogmouth was described from the Solomon Islands and placed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archaeotrogonidae
Archaeotrogonidae is a prehistoric bird family known from the Eocene and Oligocene of Europe. They are members of Strisores, and are thought to be closely related to nightjars. The remains of '' Archaeotrogon'' have been found in the Quercy Phosphorites of France, a geological formation containing Late Eocene and Early Oligocene deposits. They are primarily known from limb bones. Four species are presently considered valid. The Middle Eocene '' Hassiavis'', a more recently described bird from the famous Messel Pit in Germany, is also a member of the family. In 2021, a new genus, '' Archaeodromus'' was described from fossils found in the Early Eocene (Ypresian) aged London Clay, which are the oldest representatives of the family. They were initially thought be prehistoric trogon. However, it is nowadays generally believed that they are not very closely related to these tropical forest birds of our time, but rather convergent. The Archaeotrogonidae actually seem to be Cypselomorp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nighthawk
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 refers to members of the genus ''Chordeiles'' and related genera was first recorded in 1778. Nighthawks are medium-sized birds with long wings, short legs, and very short bills. They usually nest on the ground. They feed on flying insects. The least nighthawk, at and , is the smallest of all Caprimulgiformes. Nightjars are sometimes referred to as goatsuckers from the mistaken belief that they suck milk from goats (the Latin for goatsucker is ''Caprimulgus''). In October 2018, the University of Alberta The University of Alberta, also known as U of A or UAlberta, is a Public university, public research university located in Edmonton, Alberta, Canada. It was founded in 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Nightjar
The European nightjar (''Caprimulgus europaeus''), 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 preferred habitat is dry, open country with some trees and small bushes, such as heaths, forest clearings or newly planted woodland. The male European nightjar occupies a territory in sprin ...

Common Poorwill
The common poorwill (''Phalaenoptilus nuttallii'') 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. Many northern birds migrate to winter within the breeding range in central and western Mexico, though some remain further north. The common poorwill is the only bird known to go into torpor for extended periods (weeks to months). This happens on the southern edge of its range in the United States, where it spends much of the winter inactive, concealed in piles of rocks. Such an extended period of torpor is close to a state of hibernation and is not known among other birds. Taxonomy The common poorwill was illustrated and formally described in 1844 by the ornithologist John James Audubon from a male specimen collected on the easter ...
