May you please forward this post to HKBWS' website too?
I suspect this is a Ficedula narcissina owstoni which is a subspecies of Narcissus Flycatcher. It is potentially a full species though I am not sure about it's status at the moment. Maybe some experts can help.

我之前因為某些原因,請教過島主,如果根據島主既資料,我都覺得係Olive-backed Flycatcher, 島主分享如下:

Hi Sze
There are 3 flycatchers in this group, Narcissus (the common one), Green-backed and Olive-backed. Other names for Green-backed and Olive-backed are
Green-backed = Elisae's = Chinese Flycatcher,  scientific name ficedula elisae
Olive-backed = Owston's Flycatcher, scientific name ficedula (narcissina) owstoni
Both these have been seen in Hong Kong, but only Green-backed is officially accepted as a different species. I think the Committee are still undecided about whether Olive-backed is a separate species from Nacrissus or not. Better to ask Ho Fai or Richard Lewthwaite.

About descriptions. Firstly, only males can be easily separated, females and first-winters are for the experts only. I think you will have photos of males only.
To separate males.
Narcissus has a black back and head and bright yellow supercillium, and a bright orange/yellow throat and chest
Green-backed has a green back and head with pale yellow supercillium, and a pale yellow throat and chest
Olive-backed has an olive back, olive coloured head and yellow supercillium, and a yellow throat and chest
So Olive-backed looks part way between Narcissus (black and bright yellow) and Green-backed (green and pale yellow).
Can you see this on your photos?
Each breeds in a different area. Narcissus is mainland Japan, Green-backed is NE China and Olive-backed is the Ryukyu Islands of Japan.

Hope this helps
Geoff
