An unusual date and an interesting bird.  To me it looks rather compact and rounded winged compared to northern birds which typically have the second to fifth primaries of a similar length.  As this bird does not appear to be moult (I'm not great on pernis ageing but I think this is a juvenile/first-winter), I wonder if it a southerly breeder; i.e. of the subspecies ruficollis.  As this is potential split this is quite an interesting record.

Are there more photographs?

Any photos which show the structure well would be useful.

This may be the same bird I saw over Lam Tsuen being chased by a Black Kite on 28 Feb.

These additional photos are also very interesting.

I would urge you to submit this to the HKBWS Records Committee, I think it has a good chance of being accepted as ruficollis.
