The northern rosella (Platycercus venustus), formerly known as Brown's rosella or the smutty rosella, is a species of parrot native to northern Australia, ranging from the Gulf of Carpentaria and Arnhem Land to the Kimberley. It was described by Heinrich Kuhl in 1820, and two subspecies are recognised. The species is unusually coloured for a rosella, with a dark head and neck with pale cheeks—predominantly white in the subspecies from the Northern Territory and blue in the Western Australian subspecies hillii. The northern rosella's mantle and scapulars are black with fine yellow scallops, while its back, rump and underparts are pale yellow with fine black scallops. The long tail is blue-green, and the wings are black and blue-violet. The sexes have similar plumage, while females and younger birds are generally duller with occasional spots of red.
Found in woodland and open savanna country, the northern rosella is predominantly herbivorous, consuming seeds, particularly of grasses and eucalypts, as well as flowers and berries, but it may also eat insects. Nesting takes place in tree hollows. Although uncommon, the northern rosella is rated as least concern on the International Union for Conservation of Nature (IUCN)'s Red List of Threatened Species.

Possible
About 20% of wildlife watchers report a Northern Rosella sighting in Nitmiluk National Park on a given day, based on 115 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 33rd most-seen of the 103 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
April
In that month about 40% of wildlife watchers report a Northern Rosella in Nitmiluk National Park on a given day, against about 10% in May, the lowest month. That is one of Nitmiluk National Park's driest months, with about 45 mm of rain against 270 mm in January.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Northern Rosella sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 parks where we can rate Northern Rosella sightings, Nitmiluk National Park has the highest daily chance: about 20%. Next come Litchfield National Park (Australia, about 10%) and Kakadu National Park (Australia, about 10%).
Same family: Psittacidae
The closest relatives of the Northern Rosella that you can see in Nitmiluk National Park (family Psittacidae, New World and African Parrots) are Red-collared Lorikeet (about 80%), Sulphur-crested Cockatoo (about 60%) and Red-tailed Black-Cockatoo (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Northern Rosella is recorded against all the birds logged in Nitmiluk National Park (115 verified sightings from 2019 to 2026), 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.
