Cacatua pastinator
In 3 days <5%
The western corella (Cacatua pastinator) also known as the western long-billed corella, is a species of white cockatoo endemic to south-western Australia. Cacatuidae is one of three families of the large and diverse avian order Psittaciformes which consists of 370 species. Cockatoos are distinguished from other parrots by five main morphological features – a crest, lack of "green" dyck-texture in the plumage, yellow natal down, a gall bladder, and bridge temporal fossa
The western corella (also known as the western long-billed corella) Cacatua pastinator consists of two geographically isolated sub-species, Butler's corella (Cacatua pastinator butleri) and Muir's corella (Cacatua pastinator pastinator)
One of these two isolated populations occurs in the northern wheat-belt region of Southwest Australia, the other, consisting of larger birds occurs in the far south west of Western Australia. The northern Cacatua pastinator butleri consists of generally of smaller birds than the southern Cacatua pastinator pastinator, which indicates that the two populations may have once been connected clinally.

Rare
Under 5% of wildlife watchers report a Western Corella sighting in Perth on a given day, based on 32 verified sightings from GBIF citizen-science data. It is the 124th most-seen of the 162 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 Western Corella in Perth on a given day, so our monthly data shows no clear season.
Only Perth, in our data
Perth is the only city on Wallace's Line with enough records to rate Western Corella sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Cacatua
The closest relatives of the Western Corella that you can see in Perth (genus Cacatua, White Cockatoos and Corellas) are Little Corella (about 50%) and Long-billed Corella (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Western Corella is recorded against all the birds logged in Perth (32 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.
