Its natural habitats are subtropical or tropical moist lowland forest.
Taxonomy
The collared nightjar was formally described in 1871 by the English zoologist George Gray with the binomial name Caprimulgus enarratus based on a specimen collected in Madagascar. The specific epithet is Latin meaning "explained in detail".A molecular phylogenetic study by Kin-Lan Han and collaborators published in 2010 found that the collared nightjar was not closely related to any other species of nightjar. The authors therefore introduced a new genus Gactornis to accommodate the species. The genus name combines the four single letter abbreviations for the DNA nucleotides and the Ancient Greek word ornis meaning "bird". The species is monotypic: no subspecies are recognised.
