The images by Jackie Ong show a Black-naped Oriole (Oriolus chinensis) picking on the ripe fruits of the Common Tree-vine (Leea indica). The species belong to the family Vitaceae, of which the grape sbelong.
This plant is a large shrub to small tree, usually around 10 metres tall. The berries turn purple, then black on ripening.
This is most probably a new food record for the Black-naped Oriole.
