These geese can teach humans something about love

There is no marriage in the animal world, and so, no divorce either. But though there is no obligation to be faithful, there are birds and animals that stay together for a long time, in some cases, even for life.

Tariq and Judith, the two geese featured in the video below, have stayed together for the last eight years. Sometimes, one of them moves away, only to return to its companion. What do you think this proves? Do birds and animals really feel love, just as humans do, and does that emotion keep them together?
