In Peru, if you go deep and far enough into the Andes, you can still come across a strange tradition of a condor-bull fight.
A fully grown condor is starved for 3-4 days before the fiesta. Then, the condor is tied onto the bull's neck and the fight begins.
This is to represent the Peruvian fight for freedom: the condor, a totem animal of the Andes, represents the Incas, and the bull represents the Spanish conquistadors. Of course, the Incas must win.
The practice is now illegal in Peru for fear of condors going extinct but it still goes on in the more remote villages.
