Physical description Click here for a physical description Musk Ducks are large ducks that usually lie very low in the water. Their mainly dark-brown plumage is mottled with grey. The cap and nape of the neck are near-black. Male Musk Ducks have a large dark-brown bill lobe that females are missing. The stiff, stringy tail feathers of both sexes can be erected. Both sexes have dark irises. The massive, near triangular-shaped bill is dark-grey, the legs and feet are also dark-grey. Twitcher's tip Female Blue-billed Ducks and female Musk Ducks can be hard to distinguish. The most prominent difference is the shape of the bills. Female Blue-billed Ducks have a typical "duck-like" bill, while that of the female Musk Duck is much more massive, near-triangular and more reminiscent of a goose's bill.

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed based on sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Musk Duck is available HERE . Musk Ducks are endemic to Australia. Similar to Blue-billed Ducks, Musk Ducks are found only in the south-eastern and south-western parts of the Australian continent. Their range comprises basically all of Tasmania, VIC, NSW and the southernmost part of QLD, as well as the easternmost part of SA (including Innamincka), plus the south-west corner of WA. Musk Ducks are often found in densely vegetated swamps (both fresh water and saline) and also on open lakes.

Sightings Click here for sighting information Our first sighting of Musk Ducks was in March 2008 on two water storage dams in the area of Leigh Creek/Copley in South Australia, on the western side of the central Flinders Ranges. Musk Ducks are found only infrequently/irregularly on the western side of the Great Dividing Range. In October 2010 a female bird was seen by us at Narrabri Lake, Narrabri, NSW. Its identification (i.e., the distinction from a female Blue-billed Duck) was secured by comparison of the bills of the two species. A single male Musk Duck was spotted by us at New Quipolly Dam near Quirindi, NSW, in December 2013. At the same location a total of six male Musk Ducks were found in November 2014 and again in February 2018. A male Musk Duck was spotted at Dangars Lagoon, Uralla, NSW, in March 2012. C. Hayne reports that over 30 Musk Ducks were seen at Little Llangothlin NR, North of Guyra, in March 2012. J. Munro reports spotting a male Musk Duck on Penny Lake, King Island, near Tasmania, in December 2013. J. Greaves reports spotting Musk Ducks at Lake Claremont, Perth, WA, in January 2015, in Manjimup, WA, in March 2015, and at Herdsman Lake, Perth, WA, in August 2015. R. Plumtree reports finding Musk Ducks at the Lake Bonney Riverland, Barmera, SA, in September 2018.
