found this in the forum : "'Grey-cheeked Fulvetta'.Two recordings now exist of song from TaiPo Kau, one in 2006 and one in 2013. After comparison with song of birds in south China and elsewhere, birds in HK can be identifed as Huet’s Fulvetta Alcippe hueti. As this is the species present in Guangdong, it was agreedby a vote of 6-0 to place this species in Cat. IIA of the HK List"
So I think the ID is correct
