The white-throated nightjar or white-throated eared nightjar (Eurostopodus mystacalis) is a species of nightjar in the family Caprimulgidae. It is endemic to eastern Australia; it is a non-breeding winter visitor in Papua New Guinea. Its natural habitat is subtropical or tropical dry forests.
The white-throated nightjar was formerly known as Eurostopodus albogularis but was later reclassified to E. mystacalis. Some texts may still refer to this species as Eurostopodus mystacalis albogularis. Before 2002, this species was regarded as conspecific with New Caledonian nightjar Eurostopodus exul and Solomons nightjar Eurostopodus nigripennis. However, later research separated the three into their own species based on differences in calls and song, and morphology. Since then, E. mystacalis has remained monotypic.
The genus name Eurostopodus is derived from the Greek words eurostos meaning 'strong' and podos or pous meaning 'foot', while the species name mystacalis is derived from Latin and means 'moustache'. E. mystacalis is the largest Australian nightjar species and measures around 30–37 cm. Males and females are very similar in appearance... Wikipedia →

Rare
Under 5% of wildlife watchers report a White-throated Nightjar sighting in Brisbane on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 227th most-seen of the 237 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a White-throated Nightjar in Brisbane on a given day, so our monthly data shows no clear season.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most White-throated Nightjar sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Brisbane, in our data
Brisbane is the only city on Wallace's Line with enough records to rate White-throated Nightjar sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the White-throated Nightjar is recorded against all the birds logged in Brisbane (16 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
