This summer, the International Ornithological Congress (IOC) issued a major update to their world birdlist (Gill, F., Wright, M. & Donsker, D., 2008. IOC World Bird Names (ver. 1.7)). According to the press release, the updated list "[includes] changes of names, additions of newly described species as well as proposed splits and lumps...". As such, the IOC presently recognizes 10,354 extant species of birds in the world.

As a result of these recent changes, Taiwan has gained six endemic species, bringing the total number of endemic species to 22. Not all authorities concur with the IOC changes. For example, the Clements Checklist of Birds of the World, which is recognized by the American Ornithological Union (AOU) and the American Birding Association (ABA), accepts only 15 endemics for Taiwan. The remaining seven species are considered endemic sub-species.

The five contested species were prososed by Nigel Collar of BirdLife International in a recent research paper entitled A partial revision of the Asian babblers (Timaliidae). The full paper can viewed at Dr. Collar's website.

Rufous-crowned Laughingthrush was forerly considered a sub-sepcies of the White-throated Laughingthrush, Garrulax albogularis. The Rusty Laughingthrush was formerly one of three sub-species of Rusty Laughingthrush. It will retain both its English and Latin names, the other two sub-species were reassigned. Similarly, the Black-necklaced Scimitar Babbler was formerly a sub-species of the Spot-breasted Scimitar-Babbler. While it retained its Latin name, its common name was changed as indicated. The Taiwan Hwamei was formerly a sub-species of Chinese Hwamei, Garrulax canorus. The Taiwan Wren Babbler was derived from the Scaly-breasted Wren Babbler, Pnoepyga albiventer. Lastly, the Taiwan Fulvetta was derived from the Streak-throated Fulvetta, Alcippe cinereiceps.
