The Records Committee is reviewing photographs from the attached two threads to decide if they can be accepted as Japanese Tit, Parus minor, which would be a new addition to the Hong Kong List.

This follows an earlier review of a bird at Shek Kong Airfield Road described here

http://www.hkbws.org.hk/BBS/view ... &extra=page%3D1

which the Records Committee decided was probably a hybrid Cinereous/Japanese Tit Parus cinereous/minor.

If you look at the photographs, you will see that the Wetland Park bird has a more extensive green mantle (back), which makes it more likely to be accepted as a Japanese Tit rather than a hybrid. Cinereous Tit has a grey mantle (back) whereas Japanese Tit has a yellowish-green mantle (back).

This thread is to alert members/photographers to look carefully at Cinereous Tit including their past photographs to see whether any have a similar green mantle (back) and to publish any photographs here or send to me at

We are uncertain whether these records represent a regular occurrence in Hong Kong or vagrants in the winter of 2012/13.

Thanks
Geoff Welch
Secretary, Records Committee

由於近兩個冬季皆有帶日本山雀特徵的山雀在香港出現，所以紀錄委員會懷疑有一個日本山雀的群落在華南出現。
但由於資料所限，現時未能確定這群落是日本山雀還是日本山雀與蒼背山雀的混種。
所以現呼籲各觀友若有發現帶綠色背的山雀，請向紀錄委員會提交紀錄。

I  met a Tit family around 10 birds for 1 minute yesterday (24-04-2015) 11:45am Mai Po, road between pond #12 & 13 (correction) But sorry just took these 2 photo for a same bird.
I have sent email to Geoff already.

Thanks Sze, I have the photos.

This looks like a very young bird to me, first year.

I don't know how this affects it but the depth of green colour on the back does not seem as great as the Wetland Park bird - see here



But it's not my decision - I'll keep your photos for review by the Records Committee

this is a classical juvenil to me. They are greenish backed before get their adult plumage type.
