Hooded Duck and Spotted Hooded Duck Accidentally Fell in Love, What Should We Call Their Hybrid?

A mule was born from a horse and a donkey falling in love.

What should we call the offspring of a Hooded Duck and a Spotted Hooded Duck?

On March 28th, I sat by the Yellow River for a whole day, hoping to see a Blue-headed Pochard. Unfortunately, it seems the Blue-headed Pochard only yearns for Bird God @3. I sat with aching legs and didn't even catch a glimpse of the Blue-headed Pochard.

I didn't see the Blue-headed Pochard, but I encountered a large flock of Hooded Pochards for the first time. I also saw a Restless Creeper, too many to trigger the shutter,

And there was a surprise that made me want to write today's article: I photographed a duck with a white ring around its mouth. What is it?

The photos from left to right are Hooded Pochard male, Hooded Pochard female, Hooded Pochard female, and this last one with a white ring around its mouth is completely unrecognizable to me. But it stubbornly accompanied me all day long.

I sent the photo to bird expert @, who told me it was a Spotted Hooded Pochard, rare in Yinchuan, many people have never seen it.

However, he also said that several masters in China had a heated debate on this, and it was still uncertain what it was!

What is it exactly?
