The Crax daubentoni is endemic to Venezuela and Colombia. The Spanish name is pavón moquiamarillo or paujil de turbante.
The second picture from Wikipedia shows a female Crax daubentoni in a foreign animal jail.
It's funny what evolution can produce. Take a closer look at a male Crax daubentoni here. I reckon that yellow appendix is the equivalent of a flashy car for some other species.
