It’s tricky to imagine how a blue bill has an evolutionary advantage, but these ducks are making it work for them in WA.
If there is a duck that really enjoys a good bath, I’d say it in the Blue-billed duck. They like them so much they rarely leave the water at all.
When I watched this young gentleman splash about I couldn’t help thinking of Ernie and his Rubber Ducky song.
First a quick rinse to test the water.
A quick check of the feet.
Sing a little song, cos we all do that in the bath.
Are you watching me?
Nothing to see here.
The female blue-billed duck, well, isn’t. Blue-billed that is. In her own way she is a nicely speckled duck, and apparently looks very like a female Musk Duck. Easiest to identify by who she hangs out with.
