Nice shot, lots of feather detail and good focus. One down side to the HDR is the halo effect. Maybe if you can reduce the tonemapping (not sure if this is the correct terminology). The HDR can be very nice if not "overdone". Just my two cents, for what it is worth.
I am not a big fan of HDR as it tends to be overdone a lot. In my opinion this is one of those cases. There is a halo around the bird, a blue cast on the beak and eye and to me it looks oversharpened.
I would like to see it procesed normally with some more room all around. Great BG.
