[3] The cryptic plumage and colouration of large-tailed nightjars provide effective camouflage within its natural habitat.

A prominent row of black scapular feathers, bordered by broad buff or whitish-buff fringes, enhances their striking appearance.

[3] Additionally, males possess a white throat patch and along, broad brown tail marked with uneven dark bars.

This species is a resident of the countries of Australia, Bangladesh, Bhutan, Brunei, Cambodia, China, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, Pakistan, Papua New Guinea, Philippines, Singapore, Thailand, Timor-Leste and Vietnam.

[3] It has also been observed in agricultural landscapes, where its presence may be of significant economic interest to farmers, as large-tailed nightjars are believed to play a role in the biological control of insect pests.

[8] The large-tailed nightjar's remarkable camouflage and nocturnal lifestyle pose significant challenges for studying their behaviour and ecology.

Singing is most notable during courtship and early breeding, primarily taking place from perches or occasionally in pursuit-flights.

It has been suggested that, while ground foraging is not common, it may occur more frequently than previously thought, as a response to low abundance of flying insects.

[12] The eggs are pinkish-buff to pale yellow in colour and chicks have mealy brown feathers that ensure good camouflage in their nest site.
