WHY do scientists hang cameras on animals?

BBC cameramen equipped the animals with miniature video cameras, allowing them to learn their secrets.

The crew leader separately noted that their experiment gave them the opportunity to see the baby meerkats that had just been born.

Even scientists, who study these animals, had never seen this in the wild. Another interesting discovery was the penguins' behavior: they swam indifferently past fish, shrimp and other food objects. Perhaps, in addition to availability, the birds are guided by some other criteria.
