Black-naped Oriole eating mango

The Black-naped Oriole (Oriolus chinensis) feeds on a wide range of food that includes insects and fruits. It can be commonly seen foraging along forest edge and gardens.

Cheong Wen Chun’s study of the Black-naped Oriole eating a mango (Mangifera indica) adds on to its list of plant food. Wells (2007) lists common garden fruits like papaya (Carica papaya), star fruit (Averrhoa carambola); roadside trees and palms like acacia (Acacia auriculariformis), MacArthur palm (Ptychosperma macarthurii), wild cinnamon (Cinnamonum iners), figs (Ficus spp.) and terentang (Campnosperma auriculatum). Other plants include mahang (Macaranga spp.), Malayan teak (Vitex pubescens) and love-in-a-mist (Passiflora foetida).
