The appendices are there as separate sheets, but the Taiwan species are definitely included in the main list. Sure makes you wonder why...
Thanks for pointing that out: and with that (and a Taiwanese list) I could at least get down to the following additions to the PRC list:
Asarcornis scutulata 白翅栖鸭 White-winged Duck
Gyps fulvus 兀鹫 Griffon Vulture
Pomatorhinus schisticeps 灰头钩嘴鹛 White-browed Scimitar Babbler
Fulvetta danisi 印支雀鹛 Indochinese Fulvetta
Ficedula ruficauda 栗尾姬鹟 Rusty-tailed Flycatcher
Carpodacus grandis 喜山红腰朱雀 Blyth's Rosefinch
Zonotrichia leucophrys 白冠带鹀 White-crowned Sparrow
... though I'm just guessing that none of the following Taiwanese records have occurred on the mainland:
Nycticorax caledonicus 棕夜鹭 Nankeen Night Heron
