Why is my mallard drake's bill still green?

[Celeeste]

My drake looks normal in pretty much every other way besides the bill colour, are they not all bright yellow?

Could you post a picture?

It can sometimes look a green-ish yellow.

Duck bills come in a variety of colors: black, yellow, buff orange, grey, green, and mottled.

Oh sorry, now that I look at it, it looks a little yellow. I guess I was expecting a super striking yellow

That's normal.
