The pale-headed rosella (Platycercus adscitus), is a broad-tailed parrot of the genus Platycercus native to northeastern Australia. It is a moderate-size parrot with a pale yellow head, predominantly white cheeks, scalloped black and gold back and pale blue underparts. Two subspecies are recognised, although some authorities consider it to be conspecific with the eastern rosella of southeastern Australia.
Found in open woodland, it feeds on seeds and fruit. As with other rosellas, the pale-headed rosella nests in hollows of large trees. It readily adapts to aviculture and is sold as a cagebird. The pale-headed rosella was formally described in 1790 by the English ornithologist John Latham and given the binomial name Psittacus adscitus. The specific epithet is from Latin asciscere meaning "to approve". Latham did not specify a locality but in 1912 Gregory Mathews designated the locality as Cooktown, Queensland in northeast Australia. The pale-headed rosella is now placed in the genus Platycercus that was introduced in 1925 by Nicholas Aylward Vigors.
There are two subspecies, the nominate adscitus (Cape York Peninsula) and the better known palliceps (eastern Queensland... Wikipedia →

Possible
About 20% of wildlife watchers report a Pale-headed Rosella sighting in Brisbane on a given day, based on 2,582 verified sightings from GBIF citizen-science data. It is the 62nd most-seen of the 237 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
April and July–November
In those months about 20% of wildlife watchers report a Pale-headed Rosella in Brisbane on a given day, against about 10% in May–June and December–March, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Pale-headed Rosella sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Brisbane, in our data
Brisbane is the only city on Wallace's Line with enough records to rate Pale-headed Rosella sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Psittacidae
The closest relatives of the Pale-headed Rosella that you can see in Brisbane (family Psittacidae, New World and African Parrots) are Coconut Lorikeet (about 80%), Scaly-breasted Lorikeet (about 40%) and Sulphur-crested Cockatoo (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Pale-headed Rosella is recorded against all the birds logged in Brisbane (2,582 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.
