Believe me, the simple name of this bird accurately and unforgettably describes it.
It is a real loud Screamer - that is the name a southern screamer Chauna torquata from South America
Overview - Southern Screamer (Chauna torquata) - Neotropical Birds
"Screamers are the “guard birds” of their habitats; their trumpet-like calls can carry for several miles, warning other birds, such as Blue-throated Macaw, Orinoco Goose, and Streamer-tailed Tyrant, of approaching danger." -

you can see its reflection in the window of the enclosure and check out the expression of the child - priceless
I found it in an indoor area at the Kansas City Zoo

I could see the reflection when I took the photo and I was intentionally trying to capture it.
