I re-read James'  post and the lightbulb went on. I'm  sure the "distinct 
white patches on what I'd figure were primary coverts (top of  the "wrist" 
are what we refer to as "crescents";  translucent little arcs just inboard of  
the primaries. They are absolutely  diagnostic for Red-shouldered Hawk, and 
once they are seen well there is no need  to go further. That means it IS 
and RS. They are not white  coloring, they are areas that let light through, 
so you have to see the  bird at the proper angle against the right 
background, but once you do, the  debate is over.
