Montane Nightjar

Identification

The montane nightjar is a rather dark nightjar, measuring about 23 cm in length. It displays tawny, blackish, or chocolate-brown dappled plumage that provides excellent camouflage in its forest habitat. The most reliable field marks for distinguishing this species are sexual dimorphism in wing and tail markings: males show white spots on the four main primary feathers and white on the outer edge of the tail, while females have buff-coloured spots on the primaries and less white on the tail. The bird's distinctive call is a nasal ank-ank-ank, often followed by a high-pitched whistle piiiyu-pirrr, with the first syllable descending and then rising, and the second syllable tremulous and descending.

Range & Habitat

This species is native to upland regions of Central and Eastern Africa, with a range spanning Angola, Democratic Republic of the Congo, Eritrea, Ethiopia, Kenya, Malawi, Saudi Arabia, Sudan, Tanzania, Uganda, and Zambia. The montane nightjar occurs at altitudes between approximately 1,000 and 3,350 metres, preferring the cooler montane zones across this vast territory. Four subspecies are recognized, each occupying distinct geographical areas across this range.

The species is primarily a forest bird, though it has adapted to inhabit plantations, cultivated areas adjacent to forests, and well-wooded urban areas. Like all nightjars, it is strictly nocturnal, emerging at dusk to hunt its preferred prey of moths and other large insects. This habitat flexibility, combined with its wide altitudinal range, has allowed the montane nightjar to establish itself as a locally common species across its extensive distribution.

Behaviour & Diet

The montane nightjar is a nocturnal insectivore, spending daylight hours roosting concealed within forest vegetation before becoming active at night. It feeds primarily on moths and other large flying insects, which it pursues with the aerial agility characteristic of nightjars. The bird's cryptic plumage and nocturnal habits make daytime observation challenging, but its vocal activity at night makes it detectable to patient listeners. The distinctive nasal and whistling calls serve important territorial and breeding functions within montane forest communities.

Best Time & Places to See It

The montane nightjar is best located by listening for its calls during the early evening and throughout the night. Its wide distribution across montane forests from Ethiopia to southern Africa means that birdwatchers visiting upland regions throughout Central and Eastern Africa have opportunities to encounter this species. The bird's status as a locally common species suggests reasonable chances of detection in suitable habitat, particularly in montane forest and well-wooded areas at elevations between 1,000 and 3,350 metres. Visiting during the species' breeding season when calling activity is most pronounced will increase detection rates.

Photography Tips

Photographing the montane nightjar presents significant challenges due to its strictly nocturnal habits and cryptic plumage. Night photography techniques using flash or infrared illumination may be necessary to capture images of this dark forest bird. Daytime roosting birds are extremely difficult to locate and photograph given their excellent camouflage and preference for dense forest cover. Alternatively, photographers may focus on recording the species' distinctive vocalizations, which are far more accessible than visual documentation. Visiting known localities in montane forest habitat during peak calling periods offers the best opportunity to document this fascinating and elusive species.
