A mysterious medium-sized rail, possibly of foothill or montane grassy areas and forests. Dark brown above with a pale gray chest, a whitish throat, a barred belly, blackish legs, and a fairly long, curved reddish bill. Little known in life and mainly seen at a banding station, suggesting local migration. Similar to Slaty-breasted and Buff-banded Rails, but Luzon has a fairly unpatterned back, a longer, thinner bill, and no rufous on the head. Voice little known, although when distressed, gives a sharp “kwik!” and various squeals.
