Ho Fai is correct about the fact that this species has been split but even with the split this taxon is still Hodgson's Hawk Cuckoo Hierococcyx nisicolor; this is the breeding taxon in south China and probably breeds in HK though not proven yet. The taxon in north China H. hyperythrus (Northern Hawk Cuckoo) has a plain pinkish breast and has occurred in HK (just once  I think from memory).

Excellent photos!
