Among the 27 endemic species we can category them into:
For the partridges and pheasants:
Taiwan Bamboo Partridge: Widespread but difficult to look for. In Yingmingshan NP, Taipei there is a relateive eaiser site for them.
Taiwan (Hill) Partridge: There are two feeding sites in Dasyueshan and Alishan region.
Swinhoe's Pheasant: Not difficult to see along the roadside in good forest. There are two feeding sites in Dasyueshan and Alishan region.
Mikado Pheasant: Thre is one feeding site in Dasyueshan. In alpine region (Hehuahshan & Yushan) we can find them walking along the road. When we drive across Hehuanshan sometimes we can find them there.
The key primary birding site in mountains are:
How we organize bird tours in Taiwan
For a typical hardcore birding tour, the day we spend in Dasyueshan, Hehuanshan and Alishan/Yushan region would be 2+1+2 or 3+1+1 days.
If the time is limited, usually I would pick Hehuanshan to save the time traveling between birding sites.
If we don't care Alpine Accentor much, I would pick Alishan/Yushan region therefore we can try to see most of the breeding endemics.
If we would like to make to tour relax, it would be 3+1+2 days.
For the Styan's Bulbul, we need 1 or 2 extra days to drive to S or E Taiwan.
For the Black-faced Spoonbill (late Sept to next May) and waders (Aug-next May), we have to spend 1 extra day.
For the migratory raptors (mid-Sept to mid-Oct), it's can be combined with the Styan's Bulbuls in S Taiwan.
For the birds in Lanyu (Apr to Oct, the season with ferry): 1 or 2 extra days. Can be combined with the Styan's Bulbul in S Taiwan.
If we have 1-2 extra days, there are some secondary birding sites we can visit.
