The savanna nightjar (Caprimulgus affinis ) is a species of nightjar found in South and Southeast Asia. Eight subspecies are recognised: C. a. monticolus, C. a. amoyensis, C. a. stictomus, C. a. affinis, C. a. timorensis, C. a. griseatus, C. a. mindanensis and C. a. propinquus. Its habitat is open forest and areas with scrub. Its length is about 25 cm (9.8 in). The upperparts are brownish-grey and vermiculated, with pale brown speckles. The underparts are brown, with bars. The savanna nightjar is nocturnal and is recognizable by its characteristic loud chirping calls, mainly given in flight during the evening. The IUCN Red List has assessed the species to be of least concern because it has a large range and its population trend is stable.
Well-camouflaged nightbird, usually encountered roosting on gravel riverbeds, open areas in grasslands, rooftops, or roadsides. Sometimes found in small loose flocks when roosting. Fairly well adapted to urban life in some parts of its range and often found in towns and city edges. Intricately patterned gray-brown with less white than other nightjars; only males have a fairly small white patch on the wing near the tip. Most often detected by its distinctive, high-pitched, burry “chree-ik” song, repeated over and over.
The Savanna Nightjar is a brownish grey nocturnal bird with pale brown speckles. The underside is brown with bars. It is a nocturnal bird from eastern and south east Asia that is a vagrant in Australia. The IUCN has assessed the species to be of least concern because it has a large range and stable population trend.
The savanna nightjar (Caprimulgus affinis), also known as allied nightjar or Franklin's nightjar, is a species of nightjar found in South and Southeast Asia. Six subspecies are recognised: C. a. monticolus, C. a. amoyensis, C. a. stictomus, C. a. affinis, C. a. timorensis and C. a. propinquus. It was once considered conspecific with the chirruping nightjar. The IUCN Red List has assessed the species to be of least concern because it has a large range and its population trend is stable.
Its habitat is open forest and areas with scrub. However, it has recently moved gradually into the metropolitan areas of Taiwan, probably due to the absence of natural predators in that setting. Habitat loss is likely also a significant factor. Impacts of this relocation have included disturbed sleep for residents—due to male savanna nightjars' loud vocalizations at night from January to July—and collisions with aircraft. It is predicted to continue this habitat shift and expand its range into all major western Taiwanese cities.
These nightjar species are distributed in India, Sri Lanka, Nepal, Bhutan, Bangladesh, China and Southeast Asian countries. The savanna nightjar species are nocturnal birds with long pointed wings, short legs and short bills. There are ten recognized subspecies of these nightjars.
