Taiwan has three recorded species of Bush-Robin, the endemic species of Collared Bush-Robin, sub-endemic species of White-browed Bush-Robin, and the migrant species of Orange-flanked Bush-Robin. All these three species of Bush-Robin are the montane bird, they have the same physical size and almost similar plumage, especially the female.
White-browed Bush Robin (Tarsiger indicus formosanus, 白眉林鴝) is one of the three lifers I sighted and the only lifer I managed to digiscope in my birding trip in Dasyueshan on last Saturday.
Collared Bush-Robin (Tarsiger johnstoniae, 栗背林鴝), which I sighted in 2009 in Alishan National Forest Recreation Park. I would like to share again in this blog for the purpose of species comparison.
and besides the bird, Montane Wild Lily is also one of my lifers, haha...
Hope this blog provides sufficient information to differentiate both endemic and sub-endemic species of Bush-robin in Taiwan. Happy Birding.
