What The Duck!?!

Now it is fair to say that Australia is home to some pretty strange animals. One only has to look at the Platypus, the echidna and even the humble kangaroo. To my mind one of the strangest is the musk duck (Biziura lobata). They can be found on fresh water lakes in the southwest corner of Western Australia.

What makes them so strange? Well to start with they don’t quack like a duck. They emit a sound that is more akin to a demented sonar. They are rarely seen on land and are reluctant fliers. On the water they float very low in the water often giving the impression that just their head is above the waterline. They are prolific underwater swimmers staying under for as long as a minute and diving up to a depth of 6m and demonstrate incredible agility as they do so. In appearance they are a very dark grey to black, have a stiff tail and broad heavy bill. The males are considerably larger than the females and weigh over 3Kg while the females can weigh up to 1.5 Kg. This makes them the second heaviest diving duck in the world. The males also have a strange leathery lobe under the bill, and in the breeding season they have a very strong musk odour hence the name. The courting behaviour of the males is quite striking – they strike the surface of the water with their feet then immediately after make a couple of clucking sounds followed by a lot of whistles and a grunt. This is repeated very five seconds or so for as long as half an hour. The first time I encountered this was at Lake Seppings in Albany. I heard these odd splashes and weird sounds repeatedly coming from just beyond the reed beds but couldn’t see what was causing the commotion. As I continued walking the reeds parted sufficiently and with the help of standing on a nearby bench I was able to see what was going on. It really is quite a performance and once seen never forgotten. In Perth Musk Ducks can be seen on both lakes in the Yellagonga Regional Park and Herdsman Lake. Hard to see at first so listen for the strange noise and you’ll soon find them.

They are not hunted as they are not considered nice enough to eat and the only thing that threatens their status is the clearing and draining of wetlands.
