This is the strangest duck I have ever seen. We were treated to a mating display as this duck used its tail in its mating display, with the tail being cocked up and over the bird’s back and spread out over the water, at the same time kicking the water to produce a loud splash and also inflating the pendulous lobe. The duck is also like a submarine, often swimming with just its head visible and submerging for long periods of time
