Pick the colour of the shadow with the eyedropper tool under the wing and then use the bucket at around 10% transparency, tolerance of maybe 5-10 and start filling the shopped shadows until it reaches the right hue. Might have to undo a few times and change the tolerance up or down until you get a proper fill with our filing too much or too little.
