For observation, yes you're right. I'm not disagreeing there. We do that in nature all the time -- e.g. wildlife safaris with large telephoto lenses downwind lions/tigers/etc.
But when we experiment with dolphins, the beach ball has to be visible so we can see what the dolphin does with it (even if we're hidden behind two-way glass). If it is aliens (and I'm not suggesting it is) why can't it be that they're measuring our intelligence capacity? This is the proverbial, beach ball, as it were.
