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.
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.
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.
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.
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 buff-collared nightjar or Ridgway's whip-poor-will is a species of nightjar in the family Caprimulgidae. It is found in Guatemala, Honduras, Mexico, Nicaragua, and the U.S. states of Arizona and New Mexico.
Leucocytozoon is a genus of parasitic alveolates belonging to the phylum Apicomplexa.
Leucocytozoon andrewsi is a parasite of the genus Leucocytozoon.
Megaloschizonts are large schizonts that produce extremely high numbers of merozoites. They are found in various species of the Phylum Apicomplexa. The Apicomplexa phylum contains several parasitic protozoans. They have a very complex life cycle that includes several stages. Megaloschizonts and the smaller schizonts are the part of the life cycle that takes place inside the infected host organism and operates as an asexually reproductive cell. Megaloschizonts appear as grey-white nodules found in the smooth muscle of major organs, such as the heart, liver, lung or spleen.
The great eared nightjar is a species of nightjar in the family Caprimulgidae. It is found in southwest India and in parts of Southeast Asia. This very large nightjar has long barred wings, a barred tail and long ear-tufts which are often recumbent. It has a white throat band but has no white on its wings or on its tail.
Hematozoa is a subclass of blood parasites of the Apicomplexa clade. Well known examples include the Plasmodium spp. which cause malaria in humans and Theileria which causes theileriosis in cattle. A large number of species are known to infect birds and are transmitted by insect vectors. The pattern in which Haematozoa infect a host cell depends on the genera of the blood parasite. Plasmodium and Leucozytozoon displace the nucleus of the host cell so that the parasite can take control of the cell where as Hemoproteus completely envelops the nucleus in a host cell.
Austrosimulium is a genus of 31 species of black flies that are distributed in Australia and New Zealand. There are 2 subgenera: Austrosimulium whose species are principally from New Zealand, and Novaustrosimulium which are exclusively Australian. Austrosimulium is a sister genus to the monospecific Paraustrosimulium of South America.
Plasmodium juxtanucleare is a species of parasite in the family Plasmodiidae. The vertebrate hosts for this parasite are birds.
The Haemosporida are an order of intraerythrocytic parasitic alveolates.
Haemosporidiasina (Haemosporidia) is a subclass of apicomplexans described by Jacques Euzéby in 1988. The taxon is very similar to Aconoidasida.
Achromatorida is an order of non-pigmented intraerythrocytic parasitic alveolates belonging to the subclass Haemosporidiasina. The order was created by Jacques Euzéby in 1988.
Leucocytozoon caulleryi is a species of the genus Leucocytozoon, a genus of parasitic alveolates.
Vasily Lakovlevich Danilewsky was a Ukrainian physician, physiologist and parasitologist. He was professor of physiology at University of Kharkiv and then at Kharkiv Medical Institute. He helped to establish the Danilevsky Institute of Endocrine Pathology Problems which he directed until his death.
Leucocytozoon grallariae is a parasite found in non-migratory highland passeriforms in the families Grallariidae and Cotingidae. The species was first described by Ingrid A. Lotta, Valkiūnas Gediminas, M. Andreína Pacheco, Ananías A. Escalante, Sandra Rocío Hernández and Nubia E. Matta in 2019. Leucocytozoon grallariae is spread throughout in the Andean mountain ranges normally in humid forests and scrublands of Bolivia, Peru, Ecuador, Colombia and Venezuela.
