This photo thoroughly entertains me. The condor is totally people watching. He (or she, I’m not really sure) kept pacing back and forth, following certain people as they walked past the glass. Sometimes he would pick up a stick and parade back and forth with it. Finally, after a very long time, he grabbed one of the sticks and ran (yes, RAN) to the back of the exhibit.
Enrichment is important for captive animals; it keeps their minds healthy and active, staves off boredom and helps prevent obesity. (Yes, animals have all the same health concerns we do, too.) But sometimes the people are a type of enrichment, too.
