The Slender-billed Oriole was considered to be conspecific but is now widely accepted as full species, including the subspecies invisus from southern Vietnam, formerly placed in Black-naped Oriole. Many Black-naped Oriole subspecies probably deserve full species status since there are 9 deeply (genetically) divergent lineages [3].

Omnivorous, figs form a large part of their diet, along with fruit and berries. They also eat large insects, small animals and nestlings.

Breeding

A cup-shaped nest is made from bark, small twigs, grass and roots. The clutch consists of two to three bluish-white eggs with brown spots which are incubated for about 14 days.
