Tiny songbird of mountain and hill forests; ranges from the Himalayas south to the Malay Peninsula on the Asian mainland, with an isolated population in Taiwan’s highlands. Adult male is dark blue above and pale creamy white below, with a black stripe leading down the belly from a brilliantly red patch like a bloodstain on the breast. Female is much plainer, brownish-olive above and off-white below; lacks the bright white throat of Plain and female Scarlet-backed Flowerpeckers. Often forages at flowers blooming in the canopy. Gives a high, thin, up-and-down “tsee’ip, tsee’ip, tsee’ip” and a rising series of ticks (often ending with more metallic notes); calls include dry tick notes and high, thin “tseet”s.
