These are the wings. You make two balls and squash them down to two disks. Stick one end of the wing to the body at the height of the beak. The loose end of a wing has to be slightly spread. The number of feathers, just as the number of toes, can vary indefinitely.
Nobody's perfect, after all.
Turn the bird around. It's still sightless. Now is the time to take the safety pin again and make two tiny holes in the eyeballs. Of course it all depends on how you are going to use your bird, but still I like it best when they look upwards. Birds are so short that they have to look upwards to see you.
