I don't know their status there now but when I lived at Braemar Hill above North Point twenty years ago the following where present: Red-billed Leothrix, Silver-eared Mesia, Rufous-capped babbler and Streak-breasted scimitar babbler.  The latter three are certainly common here in Lam Tsuen now.  White-cheeked Laughing Thrush was also regular in Braemar Hill.
