I believe these signs are very important to help visitors develop an appreciation for animals. The average person is more likely to care about an animal if it is more like them- hence the disproportionate amount of attention great apes and other charismatic megafauna recieve. As a zoo volunteer over the past four years, I can attest that the questions I am asked most often are about the individual animals- not the species as a whole. They want to know what Pabu the red panda's favorite food is, not what red pandas eat in the wild. I think that if zoos put these signs at more Exhibits IN ADDITION TO informational signs, it would draw more attention to the animals and help generate interest, particularly for animals with distinct personalities or animals in large groups.
