People don’t know that they know each other until they’ve watch them. They can recognize the kinds of things that Konrad Lorenz taught us many years ago when he wrote “King Solomon’s Ring”. When he discovered that geese recognize each other by their faces, he played a dirty trick on them. He painted the face of one of the females of a particular male, and then put them back together. He attacked her, he didn’t recognize her at all. My wife has never used that much makeup, but be as it may, there are just wonderful things that can be done with social species. There was an exhibit I wanted to build many years ago called How to Exhibit a Bullfrog. And I was interested in placing the bullfrog in its world in detail, its predators, its prey, its habitat, its ecology and I wanted to illustrate to the zoo world that even a common critter like a bull frog has a wonderful story to tell.
