In an effort to be confused by every species of HK accipiter, I managed to find this bird today. I had this bird perched at Mai Po at a distance.  Then one half hour I had this bird or maybe a different bird perched in the area much closer to me.  I think the two pictures are the same bird but I am not even sure of that.  I suppose it could just be a Besra but the supercilium looks so strong in the first the picture and the dark bands seem very thin in the first picture.

What do the raptor experts think?

Richard Lewthwaite and I also saw this bird today.
We initially thought it looked big enough for a Crested Goshawk, but eventually it was clear that it it was a Besra.

Based on structure alone this has to be a Besra; the primary projection is remarkably short eliminating Japanese :

and the long and obviously thin tarsi eliminate Crested:

The tail barring as an id feature for separating Besra and Japanese applies to the upperside of the tail only.

Thanks, Mike and Paul.  That is a good point regarding the primary projections on this bird.  They are too short for Japanese.
