Peahen

A peahen, but she's wearing the male feathers. So I guess that would make her a peacock, except she's not male and she isn't even a bird.

To be honest I simply didn't know what to call this, and peahen kind of sounds like paean, which is a song of praise to Apollo. Which has nothing to do with anything, I just like any excuse to mention him.

I'm going to stop talking now
