It is difficult to determine if animals are truly ‘happy’ or ‘sad’, as their emotional states are not exactly like those of humans. Even for humans, the concept of happiness is very subjective and not easy to define. Still, there are certain behaviors that display a state of emotion that can be related to happiness. For example, the display of exploratory or playful behaviors is a good sign that an elephant has good welfare. Happy elephants are probably best observed when kept in compatible social groups. Look for elephants that touch and comfort each other, check out what each other is eating, play during bath time, care for their calves, and vocalize a variety of greetings; these are examples of contented elephants. A good camp will give elephants ample opportunity to exhibit these behaviors.
