Yes, Eurasian Siskin. An interesting record.
This would be a latest spring record for HK if accepted by RC (current latest is 4 April I think).
I had 3 on Po Toi on 17 May 2011 which were accepted as "probable ex-captives" although there was no visible sign. I wonder whether there may be a late spring passage for this species.
