In addition to our Disney Collection, Judy and I had built up a fairly large Flamingo collection. One year we were visiting Discovery Island and saw this most fantastic flamingo hat for sale, so we bought it.
When we got to the Flamingo Pond I asked Judy to stand near the side of the walkway and put on the hat, so I could take a picture of her with the flamingos.
Almost immediately after she put on the hat, all the flamingos ducked their heads. Judy felt that she had managed to embarrass the entire flock.
Later on we found out that flamingos will post four sentries to warn them of any problems. Judy was at a location where she was considered a sentry, so the flock felt that it was safe for them to all go to sleep. So Judy is the only person I know of who ever was officially considered a flamingo by the members of a flock. (You can see another "sentry" in the center standing in back.)
