The musk duck (Biziura lobata) is a highly aquatic, stiff-tailed duck native to southern Australia. It is the only living member of the genus Biziura. An extinct relative, the New Zealand musk duck or de Lautour's duck (B. delautouri), once occurred on New Zealand, but is only known from prehistoric subfossil bones. It was about 8% longer than the living species, with a particularly large head.
This animal derives its common name from the peculiar musky odour it emanates during the breeding season. Musk ducks are moderately common through the Murray-Darling and Cooper Creek basins, and in the wetter, fertile areas in the south of the continent: the southwest corner of Western Australia, Victoria, and Tasmania.
Adult males are 60 to 70 cm (24 to 28 in) long and have a distinctive large, leathery lobe underneath the bill; females are 47 to 55 cm (19 to 22 in) long and unadorned. Their drab dark grey-brown, slightly pin-striped plumage is inconspicuous and does not differ between the sexes. This species weighs an average of 2,398 g (5.287 lb) in males and 1,551 g (3.419 lb) in females, with the smallest females weighing only 993 g (2.189 lb) and the largest males weighing... Wikipedia →

With luck
About 10% of wildlife watchers report a Musk Duck sighting in Flinders Chase on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 59th most-seen of the 68 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
January and February
In those months about 20% of wildlife watchers report a Musk Duck in Flinders Chase on a given day, against under 5% in March–July and September–December, the lowest months. Those are among Flinders Chase's driest months, with about 30 mm of rain a month against 100 mm in August. August has too few records to rate.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Musk Duck 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 5 parks where we can rate Musk Duck sightings, Flinders Chase has the highest daily chance: about 10%. Next come Grampians National Park (Australia, under 5%) and Hattah-Kulkyne National Park (Australia, under 5%).
Same family: Anatidae
The closest relatives of the Musk Duck that you can see in Flinders Chase (family Anatidae, Ducks, Geese, and Swans) are Cape Barren Goose (about 50%), Pacific Black Duck (about 10%) and Black Swan (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Musk Duck is recorded against all the birds logged in Flinders Chase (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.
