As a young boy, I always thought this bird had a strange name. You know a cock to be a rooster, and then learn a slang term for the word cock, and it all seems so strange.
Whatever the case, the bird itself is very cool looking and one of my favorites. I believe it is geographically located to Peru and the Andes Mountains.

There are several of them in residence at the San Diego Zoo. Such a beautiful bird.
