It's not a parrot, it's in the Cotinga family which, unfortunately, is a very confusing and disputed group of about 40-100 species, depending on whose DNA work is being used. About all you can say of the family is that it's tropical, New World, and most of them eat fruit. They aren't mimics per se, but one of the subgroups in the family is the Bellbird group, all of which make metallic BONK noises that sound like cracked bells, if you have a good imagination. Another cotinga is the Screaming Piha whose call is omnipresent in lowland forests, and if you ever get close to one it'll make your ears bleed. They don't call it the "screaming" piha for nothing.
The Andean COTR (in the photo) prefers steep hillsides in dense vegetation, and the only time I ever saw them they were hustling up and down such a hill - it was like watching little orange footballs being thrown by unseen quarterbacks. No chance of a photo, but for birders any look at one of these makes for a good day.
