The black wallaroo (Osphranter bernardus), also known as Woodward's wallaroo, is a species of macropod restricted to a small, mountainous area in Arnhem Land, Northern Territory, Australia, between South Alligator River and Nabarlek. It classified as near threatened, mostly due to its limited distribution. A large proportion of the range is protected by Kakadu National Park.
The description of the species was published by Walter Rothschild in 1904. The author initially assigned the species to a new genus as Dendrodorcopsis woodwardi, but revision of new material forwarded to England by the collector John Tunney persuaded the mammalogist Oldfield Thomas that the characteristics of the taxon were assignable to Macropus.
The specific epithet woodwardi was preoccupied by another subspecies of the genus (Macropus robustus woodwardi), prompting Rothschild to assign the new epithet bernardus. In 2019, a reassessment of macropod taxonomy determined that the species should be moved from the genus Macropus to the genus Osphranter. This change was accepted by the Australian Faunal Directory in 2020.
Other common names of O. bernardus also include black kangaroo, northern black wallaroo... Wikipedia →

Possible
About 20% of wildlife watchers report a Woodward S Wallaroo sighting in Kakadu National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 5th most-seen of the 11 mammals 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.
January and February
In those months about 40% of wildlife watchers report a Woodward S Wallaroo in Kakadu National Park on a given day, against under 5% in March–April, June, September and November, the lowest months. Those are among Kakadu National Park's wettest months, with about 320 mm of rain a month against almost none in August.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Woodward S Wallaroo sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Kakadu National Park, in our data
Kakadu National Park is the only park on Wallace's Line with enough records to rate Woodward S Wallaroo sightings: about 20% of wildlife watchers there report one on a given day.
Same genus: Macropus
The closest relatives of the Woodward S Wallaroo that you can see in Kakadu National Park (genus Macropus, Grey Kangaroos) are Agile Wallaby (about 60%) and Wallaroo (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Woodward S Wallaroo is recorded against all the mammals logged in Kakadu National Park (11 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.
