Our only full birding day was Thursday 9th Jan. We started with a quick stop at the top where I heard (and got a glimpse of) what must have been Luzon Montane Racquet-tail. Then we split up, with me looking for Benguet Bush-Warbler while the others went to find the Luzon Water Redstart. Neither of us were successful, though I did get a lot of the usual Mt Polis birds including; Chestnut-faced babbler, Mountain Leaf-Warbler, Mountain Tailorbird, Luzon Bush-Warbler, Long-tailed Ground-Warbler (heard), Metallic-winged Sunbird, Fire-breasted Flowerpecker and Mountain White-eye.
A short walk into to forest at the pass added Island Thrush to the list.
Banaue Hotel grounds was also nice, with Mountain Verditer and Yellowish White-eye. We eventually caught up with the Luzon Water Redstart near Banaue, at a bridge called Guihob Bridge.
