Sierra Madre Ground-Warbler Robsonius thompsoni

A medium-sized bird of the forest floor from the lowlands to low elevations in the mountains in northeastern Luzon. Fairly stout, with a pale lower bill, long legs, and large feet. Pale below, with a grayish, faintly scaled chest and brown under the base of the tail. Note rufous face and forehead with pale bare skin in front of the eye, brown upperparts with two dotted white wingbars, and chestnut flight feathers. Note the white throat with black speckling below and a thin black moustache stripe. Unmistakable. Song consists of a very high-pitched “tseeee-sip tsee-wee!”
