Any ideas what kind of duck this is?

I looked in the bird guide that I have for Arizona and I can not find this one listed. Someones pet that they let go or got loose?

I believe he escaped from Graceland!!

Princess Leia Duck.

That's the crested duck, look it up

Yeah, crested duck, essentially a mallard that has had a few generations of selective breeding.

An example of people deliberately encouraging and exaggerating a genetic malformation which creates creatures that have problems in life and often suffer from the malformation, but look cute. In this case it is a skull that doesn't properly form and fatty tissue covers the resulting hole and creates the crest.

Sorry for the delayed response. Thank you so much for the replies! Never seen one around here in Arizona before or anywhere else. I figured it might be from some other country that someone had as a pet that got out or let loose.
