Thank you Xiaoxuan These pictures look exactly like the duck I saw.

Here's a juvenile male Mandarin:

I thought it was a female mandarin duck, but I got confused by the orange beak and the brown patch on top of the head. Still I can't find any pictures ore information on changing young male mandarin ducks.

This is a Mandarin duck...it's male in eclipse phase
