Yellow-Vented Flowerpecker

The yellow-vented flowerpecker is a 9–10.5-centimetre bird with yellowish-olive upperparts, mostly white underparts boldly streaked blackish, a whitish loral stripe and unmistakable orange-yellow undertail coverts. Juveniles are greyer below, with duller streaks and a paler yellow vent. Its elongated outermost primary feathers are unusual among flowerpeckers and provide an additional structural distinction (Birds of Singapore; Wikipedia, general species account; Encyclopedia.com).

It ranges from the Himalayan foothills through Indochina to the Greater Sundas, using moist lowland and montane forest, secondary growth, forest edge, gardens and orchards. Birds feed at varying heights on mistletoe berries, small figs, nectar and insects. Both sexes help build and incubate at the concealed nest; general accounts report two or three white eggs and breeding from April to August, though timing varies geographically (Birds of Singapore; Encyclopedia.com; Bird Ecology Study Group).
