The tiny Plain Flowerpecker Dicaeum minullum ranges from India to the Greater Sundas, with olivaceum in southeastern Tibet to Sichuan and eastward to Guangdong, the nominate race on Hainan, and uchidai on Taiwan. Inhabits hilly forests at low elevations, typically high in the trees feeding in clumps of mistletoe; also takes nectar and insects. Upperparts olive-brown from crown to very short tail; pale head sides and lores. Underparts greyish-white but center of belly creamy. Slender, slightly decurved bill is black (pink in young); feet black. Call a series of short, clear whistles and brief squeaks; song thinner and more fluid. — Craig Brelsford
