Common or Siberian Chiffchaff? Please ID ..

It has been suggested by someone that the Siberian is the most easterly of the chiffchaffs and therefore most likely to occur in Hong Kong .. Also, the nominal "common chiffchaff" has much more olive/greenish hue in the upperparts.

The Chiffchaffs that occasionally turn up in Hong Kong (this is the 7th record, I think) are Siberian Chiffchaffs [i]Phylloscopus collybita tristis[/i]. At the moment, the IOC lists [i]tristis[/i] as a subspecies of Common Chiffchaff and this is followed in the Hong Kong Bird Reports.
However, it is possible that some time in the future, [i]tristis[/i] will gain specific status. Modern field guides to Asian birds e.g Brazil (2009) and Rasmussen (2005) tend to treat [i]tristis[/i] as a separate species.
