This is actually an ibex, probably a female though possibly a young male - difficult to tell from this angle. Nice photo though.

Thanks! I couldn't remember the name, so guessed. It wandered across that rock it's on as we were eating lunch. It was about 100m away, and this was with a 90mm equivalent lens. I haven't had to crop it at all.

Title changed! (for anyone reading this later and not knowing what we're talking about, I'd mis-identified it as a Chamois)
