The photo I posted shows them on the deck.
Condors are scavengers who eat carrion. They don't attack living animals. It wouldn't surprise me if they would get aggressive if you threatened their nest, but I don't recall ever hearing of a condor attacking a human.
Sorry, I meant would they attack the people if the people walked out on to the deck. You already answered though.
I don't think they are old enough to be pairing off to nest. Then again, I don't know anything about condors except I once remember seeing this amazing video footage of a bunch of them on a aircraft runway. They were so big some had 7 foot wing spans and they grounded all flights because they are an endangered species and there were so many of them on the runway. There was no way for an aircraft to lift off safely. It was an awesome piece of footage.
Then there's this awesome piece of footage you have probably already seen...
Heart warming moment condor shares a hug with rescuer. This is the heart-warming moment when a condor revisits the man who rescued it as a chick. The two are captured sharing a hug, as the condor is seen nuzzling the man known as Edgardo affectionately.
