I've seen condors in captive settings and I've even been in a clinic when one was sedated for examination and got to touch it. But I wondered how something that huge flies. It's kind of like seeing a giant bustard fly, you can't imagine it until you actually see it.
As my fellow park service employees found out about my interest in birds they all wanted to know what I wanted to see. When they learned it was a condor they were all eager to help. I loved how everyone had a vested interest in helping me find a condor--isn't that just like a park ranger, make sure the visitor gets the experience they want. I wasn't too worried. Sure I wanted to see one right away, but I knew I had ten days to find a condor, it had to happen. There are roughly 72-ish birds using the area, one had to fly over at some point. The first few times we went to the canyon as part of our training, I tried to play it cool...but of course I had my scope with me. I got a fast education of just how many turkey vultures and common ravens roam the skies.
Everyone was pointing to large soaring birds asking if I had seen them. "Yes, I saw the turkey vulture." Or to be technical, one day I did say, "Yes I see the turkey vulture...oh wait...oh crap, that's a zone-tailed hawk which flies like a turkey vulture--bonus!"
