The Pacific black duck (Anas superciliosa), commonly known as the PBD, is a dabbling duck found in much of Indonesia, New Guinea, Australia, New Zealand, and many islands in the southwestern Pacific, reaching to the Caroline Islands in the north and French Polynesia in the east. It is usually called the grey duck in New Zealand, where it is also known by its Māori name, pārera.
The Pacific black duck was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the other ducks, geese and swans in the genus Anas and coined the binomial name Anas superciliosa. Gmelin based his description on the "Supercilious duck" that had been described in 1785 by the English ornithologist John Latham in his A General Synopsis of Birds. The naturalist Joseph Banks had provided Latham with a water-colour drawing of the duck by Georg Forster who had accompanied James Cook on his second voyage to the Pacific Ocean. His picture was drawn at Dusky Sound, a fiord on the southwest corner of New Zealand. This picture is the holotype for the species and is now held by the Natural History... Wikipedia →

Very likely
About 70% of wildlife watchers report a Pacific Black Duck sighting in Perth on a given day, based on 6,879 verified sightings from GBIF citizen-science data. It is the 6th most-seen of the 162 birds we can rate there. Over three days the chance rises to over 90%, if each day is a fresh chance.
January and November
In those months about 80% of wildlife watchers report a Pacific Black Duck in Perth on a given day, against about 70% in February–October and December, the lowest months. Those are among Perth's driest months, with about 20 mm of rain a month against 130 mm in July.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Pacific Black Duck sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 6 cities where we can rate Pacific Black Duck sightings, Perth has the highest daily chance: about 70%. Next come Melbourne (Australia, about 60%) and Brisbane (Australia, about 60%).
GBIF citizen-science records
It is estimated from how often the Pacific Black Duck is recorded against all the birds logged in Perth (6,879 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.
