Savanna nightjar

The savanna nightjar, sometimes also allied nightjar or Franklin's 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.[2] Its habitat is open forest and areas with scrub.[3] 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.[4] The savanna nightjar is nocturnal and is recognizable by its characteristic loud chirping calls, mainly given in flight during the evening.[4] Their acoustic features change and can preadapt based upon their habitat.[5] 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.[1]
