cinema animation to unity

Hi all,

I've got this very simple animation of a bird flapping it's wings, made in cinema 4d and imported in unity..
When I hit the play-button in the animations tab of the inspector, the bird moves as foreseen. However, when I import it, it does not move at all. I am making a terribly noob-ish mistake, I am sure,.. but I can't seem to figure I what I am doing wrong...
Help?

Thanks so much,

Alex
