Game Factory Weird birds (d)

This card game takes the cake. Nine really weird ones, to be precise. To win, all you have to do is collect all nine - preferably as many of each as possible. But be careful, only an odd number of them will give you points at the end. Fortunately, there are always two birds pictured on the back, but who knows which one it really is. You'll end up grumbling like a raven if you mess up a whole load of points. Perhaps you would have been better off foisting it on one of your opponents like a cuckoo's egg?
