The bright scarlet-red chest of the otherwise bumblebee-colored male glows in the gloom of the forest like a demon’s eye. Female is much more modestly-colored, with a gray head, a yellow breast, whitish flanks, and a dull brownish-yellow back. Female Yellow-rumped Flowerpecker has more evenly yellow underparts. A generally uncommon species, found patchily in forest and forest edge in lowlands and foothills. Gives buzzy “tzeeps” as well as high-pitched trills.
