White-throated Nightjars are medium-sized nocturnal predators.
Their plumage is
highly cryptic.
They are primarily dark grey-brown, with rufous and grey streaking
and barring. They have small white spots on both sides of the
throat. While perched on the ground, the dark-grey wing tips tend
to stick out conspicuously. The eyes are dark-brown and have the
typical, unusual form of other nightjars. The small, downward-curved
bill is dark-grey.

Twitcher's tip |

They are distinguished from Spotted Nightjars by
their more dark-grey general appearance, also in-flight, when their
finely barred underparts show. In-flight the main distinction between
the two species is that White-throatted Nightjars do not have prominent
white spots on their outer primaries, but more prominent white patches
on either side of the throat.

White-throated Nightjars occur in Australia, eastern Indonesia,
New Guinea and on the Solomon Islands.
Nominate race "mystacalis" breed only
in Australia and migrate to the continent from the North via the
Torres Strait. In Australia they populate only the eastern coastal
fringe and adjacent Great Dividing Range in an up to 300 km wide
area, from the eastern half of Cape York peninsula, QLD, all the
way down to about Melbourne, VIC. Occasionally, they can be found
a bit farther inland, on the western side of the Great Dividing
Range.
White-throated Nightjars have a preference for (mostly dry)
forest and
woodland,
especially areas with lots of litter (leaves, twigs, bark),
which they use for camouflage.

We first found at least 3 White-throated Nightjars, race
"mystacalis",
in Deriah Aboriginal Area in February 2014.
After their winter absence, White-throated Nightjars, race
"mystacalis",
returned to Deriah Aboriginal Area in October 2014, when
they were heard calling from two locations in a densely wooded
gully, close to where they had been found the previous season.
In November one White-throated Nightjar was seen in-flight and
visually identified at the same location. Since then they are
heard in the same area every year during the breeding season.
In March 2017, late in the season, a White-throated Nightjar, race
"mystacalis",
was heard calling at Dandry Gorge AA, in the southern
Pilliga scrub.
In December 2017 a White-throated Nightjar, race
"mystacalis",
was found at Timmallallie NP, in the
Pilliga scrub.
M. Adam-Cross reports having heard White-throated Nightjars, race
"mystacalis",
calling at night during spring and summer in Yarramundi, NSW, for many years.

(Bad) lateral view of a White-throated Nightjar on the ground;
the white throat is clearly visible; in this shot taken with a
flash one can also see that White-throated Nightjars have reflective
plumage; this is the
bird whose calls were recorded on 9 December 2017
[Timmallallie NP,
NSW, December 2017]
White-throated Nightjars usually do not perch on shrubs or trees;
they are either found by us on the ground or in the air.
