Not sure if we were particularly lucky, but we saw & photographed LOTS of these fabulous birds, set against the Andean back-drop. Our best sighting was ten minutes before the actual Condor's Cross location, where half a dozen adult & juvenile birds were swooping across the road and into the canyon, but just above our heads. Amazing photos. At the viewpoint proper we were a little further away, but now looking down on top of the birds. Absolutely stunning view of wildlife.
