In 2004, I visited Peru and amongst all the places I visited was Colca Canyon for its famous condors:

They were obviously going for the dead animal down in the valley.
We saw the locals: lovely people.

Then our tour guide told us that nowadays, in order to attract tourists, the locals pushed cows into the canyon to keep the condors happy.
