Making and animating bird

So I modeled a bird for the BGE, I think that I did amazing.

But when i (tried) to rig it, it all went wrong… Can someone help me?

This is the .blend file
birdanimation.blend (1.02 MB)

The shape looks great the mesh looks bad. You needs to look at some meshes and see how they work. I would retopo the whole thing. quads with loops around the body where it flexes. The easiest way is just look at other good meshes.

I have to say blender has some powerful tools under the hood and excellent rendering engine. But to really get it to take off someone has to have the courage to give people a different user interface. Everyone knows how good this program is, but learning curve is a bit frightening !
