"European Nightjar" [3] Like other aerial birds, such as swifts and swallows, nightjars make a quick plunge into water to wash.[22] They have a unique serrated comb-like structure on the middle claw, which is used to preen and perhaps to remove parasites. See also Tropical savanna and grassland biome. The males, and sometimes females, often have white markings in the wing or tail. This wing clapping probably serves a number of purposes and is a form of communication generally directed at other European nightjars. A terrestrial biome found in temperate latitudes (>23.5° N or S latitude). (Brooks, et al., 1985; Cleere, 1998), European nightjars are associated with a great variety of habitat types and elevations including moors, orchards, near deserts, wetlands, boreal forests, Mediterranean scrub and young birch, poplar, or conifer stands. (Brooks, et al., 1985), As of 1983 the oldest banded individual was recorded as 8 years old, but more recent estimates suggest European nightjars might live as long as 11 years. The eggs may be marked or blotched irregularly and weigh between 7 and 9.9 grams. Migration is mainly at night, singly or in loose groups of up to twenty birds. [3], Birds hunt over open habitats and woodland clearings and edges, and may be attracted to insects concentrating around artificial lights, near farm animals or over stagnant ponds. BTOweb Birdfacts. The semi-precocial downy chicks are mobile when hatched, but are brooded to keep them warm. Caprimulgus europaeus sarudnyi is medium-sized, and lighter colored than European subspecies, but more dominantly brownish than the gray C. europaeus unwini. Caprimulgus europaeus meridionalis is found in Western Europe, Northern Africa and east Mediterranean countries. [4], Parasites recorded on the European nightjar include a single species of biting louse found on the wings,[37] and a feather mite that occurs only on the white wing markings. Convergent in birds. forest biomes are dominated by trees, otherwise forest biomes can vary widely in amount of precipitation and seasonality. The maximum known age in the wild is just over 12 years. [8] Old or local names refer to the song, "churn owl", habitat, "fern owl",[9] diet, "dor hawk" and "moth hawk". Singing is more frequent at dawn and dusk than during the night, and is reduced in poor weather. He patrols his territory with wings held in a V and tail fanned, chasing intruders while wing-clapping and calling. It consumes grit to aid with digesting its prey, but any plant material and non-flying invertebrates consumed are taken inadvertently while hunting other food items. Habitat loss and the use of pesticides has been blamed for these shrinking numbers. Young chicks have been known to eat their own faeces. They winter in Africa, primarily in the southern and eastern reaches of the continent. The largest and most widespread genus is Caprimulgus, characterised by stiff bristles around the mouth, long pointed wings, a comb-like middle claw and patterned plumage. Additional support has come from the Marisla Foundation, UM College of Literature, Science, and the Arts, Museum of Zoology, and Information and Technology Services. John McCallen (author), Stanford University, Terry Root (editor, instructor), Stanford University. Wing clapping also occurs when the male chases the female in a spiralling display flight. They flew out of the trees above the track right infront of us, and seemed to land in a tree on the other side of the track. Fat is accumulated before migration to aid in the journey south.

[15], All populations are migratory, and most birds winter in Africa south of the Sahara, with just a few records from Pakistan, Morocco and Israel. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. May 28, 2007 [3], Broods that fail tend to do so during incubation. [21], Nightjars have relatively large eyes, each with a tapetum lucidum (reflective layer behind the retina) that makes the eyes shine in torchlight and improves light detection at dusk, dawn and in moonlight. The extreme cryptic markings of this species allow individuals to conceal themselves in broad daylight by perching motionless on a branch or stone and mimicking their substrate. 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. From about 19 days on, the young may accompany the male on foraging trips; he feeds his young on the ground or at the nest. [43] It is likely that the birds were attracted by insects around domestic animals, and, as strange nocturnal creatures, were then blamed for any misfortune that befell the beast.

European nightjars generally employ crypsis as their first defense. [24] The European nightjar has been observed in captivity to be able to maintain a state of torpor for at least eight days without harm, but the relevance of this to wild birds is unknown.
