Looks like your smoothing groups are a bit messed up..
The model itself looks likes its cut out of a wooden plate, it works ok in the side view but 2/3 and front view looks a bit "extruded" especially the beak looks very flat and not too organic. basically the entire middle part is flat. I'd add another row of vertices there and get rid of some that are used in the body without defining the actual shape of it any further. The beak should also be seperated more visibly from the head, as well as the wings from the body.
