Thanks for sharing your images and commentary! Your English is MUCH better than my Russian.
BTW, I'm not 100% sure, but the bird shot taken by your friend Sergy looks like a White-browed Hawk. (not to be confused with the White-browed Hawk-owl of Madagascar!) Beautiful photo anyway.
Mike.
P.S. chinchillas are ranched for their very soft fur - maybe not in Peru, but elsewhere...
