Mindanao Plumed-Warbler Micromacronus sordidus

A tiny and uncommon bird of foothill and lower montane forest on Mindanao. Yellowish to off-white below with a small eyebrow mainly in front of the eye, brown upperparts, and a grayish head. Note the reddish eye and the long white plumes sprouting from the sides, lower back, and rump. Somewhat similar to female Little Pied-Flycatcher, but smaller, with white plumes. Voice includes constant high-pitched “seep” notes and a sibilant chatter similar to a white-eye’s.
