Distribution and habitat
It is found in Southeast Asia with populations in the Western Ghats and Sri Lanka Bangladesh, India, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Thailand, and Vietnam.
Its natural habitat is subtropical or moist lowland tropical forests.
Like other nightjars they are active at dusk and at night. They have a distinctive call which includes a sharp tsiik followed by a pause and a two-syllable ba-haaww.
The nest is a scrape on the ground and the clutch consists of a single egg. The chicks are well camouflaged among leaf litter.
Several populations are given subspecies status and include:
- the nominate form macrotis (Vigors, 1831) from the Philippines
- bourdilloni (Hume, 1875) of the Western Ghats
- cerviniceps (Gould, 1838) along the eastern Himalayas into Indochina and northern Malaysia
- jacobsoni (Junge, 1936) of Simeulue Island
- macropterus (Bonaparte, 1850) from the islands of Sulawesi, Talaud, Sangihe, Banggai and Sula
