Liz Bonnin on Animals In Love: How a pair of greylag geese could rival any great romance

Filming Animals In Love was an eye-opening experience in so many ways. Not only did I witness animal behaviours I hadn't seen before, but it also allowed me to understand a lot more about emotional intelligence in animals. 

Until very recently we believed animals were not capable of emotion. But over the past two decades great advances have been made in the study of animal behaviour and we now know that many animals experience emotions like fear and joy.
