The Australian owlet-nightjar (Aegotheles cristatus) is a nocturnal bird found in open woodland across Australia and in southern New Guinea.

The Australian owlet-nightjar was formally described as Caprimulgus cristatus in 1790 by the English naturalist George Shaw based on a specimen collected in New South Wales, Australia.

The Australian owlet-nightjar was previously placed in Caprimulgiformes but updated taxonomy now places it in Aegotheliformes. The Australian owlet-nightjar is now one of ten species placed in the genus Aegotheles that was introduced in 1827 by the naturalists Nicholas Vigors and Thomas Horsfield. It is the type species of the genus. The specific epithet cristatus... Wikipedia →

Rare
Under 5% of wildlife watchers report an Australian Owlet-nightjar sighting in Melbourne on a given day, based on 34 verified sightings from GBIF citizen-science data. It is the 211th most-seen of the 236 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 an Australian Owlet-nightjar in Melbourne on a given day, so our monthly data shows no clear season.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Australian Owlet-nightjar sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Yes
Of the 3 cities where we can rate Australian Owlet-nightjar sightings, Melbourne has the highest daily chance: under 5%. Next come Sydney (Australia, under 5%) and Brisbane (Australia, under 5%).
GBIF citizen-science records
It is estimated from how often the Australian Owlet-nightjar is recorded against all the birds logged in Melbourne (34 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.
