The eastern rosella (Platycercus eximius) is a parrot native and endemic to south-eastern Australia. It was first introduced to New Zealand in cages, and individuals were subsequently intentionally released or accidentally escaped into the wild. In New Zealand, it is now established in the North Island (notably in the northern half of the island, Taranaki, Waikato and in the Hutt Valley) and in the hills around Dunedin in the South Island.
The eastern rosella belongs to the genus Platycercus and subgenus Violania along with other three species members: northern rosella (P. venustus), pale-headed rosella (P. adscitus) and western rosella (P. icterotis). An early analysis of rosella phylogeny stated that the eastern rosella and pale-headed rosella are most closely related to each other, compared to the other two rosella species. However, a more recent mitochondrial study found that the eastern rosella was the earlier offshoot of the lineage that split into the pale-headed and northern rosella, and those non-sister taxa were hence able to hybridize.
The three subspecies of eastern rosella are: P. e. eximius, mainly found in Victoria and southern New South Wales, Australia... Wikipedia →

Possible
About 30% of wildlife watchers report an Eastern Rosella sighting in Melbourne on a given day, based on 10,428 verified sightings from GBIF citizen-science data. It is the 34th most-seen of the 236 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.
September
In that month about 40% of wildlife watchers report an Eastern Rosella in Melbourne on a given day, against about 20% in February and March, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Eastern 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.
2nd of 4
Of the 4 cities where we can rate Eastern Rosella sightings, Melbourne ranks 2nd at about 30%. The best odds are in Auckland (New Zealand, about 40%).
GBIF citizen-science records
It is estimated from how often the Eastern Rosella is recorded against all the birds logged in Melbourne (10,428 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.
