What parrot with a penis?

I remember reading a long time ago about a parrot with a sort of retractable penis, I believe it was black in plumage and the males lost some of its feathers during mating season(I think it was his head feathers). I can't remember the name of this parrot and I thought I'd find it easily with google but that doesn't seem to be the case. It's bothering me that I can't remember what it is. Maybe it wasn't a parrot that I read about? I'm PRETTY sure it was though. Excuse the terrible title, *What parrot has a penis?*
